week 12

Assalamualaikum and hi everyone!!!

We just finish Life Without Microbe event!!!!, feeling very grateful and relief  because finally we have finished this big event. It's very awesome and I think we should do it again. From this event, we got to know how to handle a big event in the future. My part is to handle and keep the receipt for this event and pass it to Dr Wan. For me when we are going to make an event to come true and run smoothly everyone should give a good cooperation and just do whatever we can do and help and I can see it in this program. Everyone show a good cooperation and very helpful. 

We invite students of form 4 and form 5, from SMK Warisan Puteri. They arrive UPM at 9 o'clock and its a little bit messy in the morning because we haven't finished decorate and put a poster yet  but thank God it run smoothly after that. In the hall, we do a very interesting activities with the student and I became the facilitator with Aina for my group. Our group named Bacillus cereus. Aina and I choose this name because we want them to be serious doing all the activities..hehe..During the event there only one thing that I think it is wrong which time when the first year students for biocell and biochemistry come in and asking us question without a proper way to approach and we are very busy at that time. Sorry to them because I'm busy with my new sisters and brothers at that time. I think that's all from me. I'm having a great semester with Dr Wan and all of my classmate. Thank you for that. 

Last but not least, this is my extraordinary team!! ^_^

week 11

Assalamualaikum and hello !!!

So as you can see this is a week 11 where this week I have a lot of work to do and busiest week ever. This week in microbial ecology class we have learnt on two topic which is food spoilage and waste water. Both topics are interesting but for me, I have more interest on food spoilage. This is because I can be more alert on what should I take and what I should not take. This week class is fun and a little bit relax because we do a lot of activities such as do a crossword, quizzes and presentation from the waste water group instead of just having a lecture. Even though we have a little bit network problem while doing the quizzes, it not the obstacle for us to finish it. I have a lot of fun in this week class. I want to say sorry to Dr. Wan because I didn't go to class on Thursday morning because I'm feeling unwell on that day. Okay, that's all from me for this week. Can't wait for next week because we will have our first big event together with all of my classmate. Hope everything will run smoothly.

week 10

Assalamualaikum and hye everyone we meet again in week 10. ^_^

In this week, we have continued our lesson on the topic of Human microbial ecology. We continue at the subtopic of pathogenesis of pathogen. There are 5 sequence, first is Entry, then specific adherence, third is the invasion, fourth is on the colonization and growth and finally is the host damage. For me, this topic is quite challenging because we need to do lot of memorization such as memorize the name of microorganism in a specific place and also needs to differentiate between the toxins and so on but I like to discover and learnt about this topic because from it I got to know what kind of bacteria can be found on my skin, mucous membrane, gastrointestinal track and also in my mouth. Then, we discuss in what topic that gonna be in our test 2. Its is very helpful for me. That's all from me for this week. Thank you for spending your time reading my blog.

week 9

Assalamualaikum and hye this week we learnt about the Human Microbiome. In this topic, we learnt about the ecosystem in the human body and we also learnt on the differences between the normal flora and pathogenic microbe. For me I think this topic is interesting but not interesting as atmosphere :). The flipped classroom that has been prepared for us is really creative and informative especially the infographic that they make. Everything is okay for this week. That's all from me thank you for spending your time reading my blog.

week 8

Assalamualaikum and hey everyone!!!!

This week we are studies on the topic about the Atmospheric habitat. The same topic with my Thinglink (https://www.thinglink.com/scene/647784953760710657) and I found that there are many things that I didn't know yet. Personally I really like on the atmosphere because there are many microorganisms in it which we cannot see with our naked eyes. From what I learnt atmosphere consist of 6 region Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere and Ionosphere.  Before the class start, we must do an exercise provided by one of the groups in our class. The video is very nice and gives me more understanding in this topic. This topic is really interesting because I got to know one beneficial and awesome bacteria which is can turn water into an ice. This ice nucleating bacteria is Pseudomonas syringae. For Friday, we go into the Human Body Ecosystem. Like usual before coming to the class we must do an online exercise provided by a group that have been choosen that topic. I like the way their presenting the quizzes, its interesting and doesn't look boring.. In the class, we only go through a bit on this topic and will be continued next week. That's all from me. ^_^

Week 7

Assalamualaikum !!! we meet again in week 7.

For this week we continue our lecture on the Microorganism in the Terrestrial Ecosystem. There are 4 types of microbe plant interactions which is epiphytes( microbes that live on the surface of plants), endophytes(microbes that colonize internal plant tissues), some microbes live in the aboveground and also some microbes that inhibit below ground plant tissue.

The role of microbes in Rhizosphere and Rhizoplane(surface of root)

• labile source of nutrients, creating microbial loop
• synthesis and degradation of organic matter
• promote plant growth
• associate in nitrogen fixation

Microbial loop

Mycorrhizae

• a mutualistic plant-associations 
• there are two types of mychorrhizae association which is endomycorrhizae and ectomycorrhizae.
• important to plant

soil population - protozoa

3 general function of soil protozoa

1. Mineralizing nutrients
2. Regulating bacteria populations
3. Food source

Next, we study on the Hydrosphere. Before we go for a lecture on Thursday, we must do some exercise that has been provided by group 4. 

Here are the exercise that we do:

Explanation in thinglink. Very creative!!!

They even make a mind map for us. Thank you

Then, we do a crossword and its really challenging.

Hydrosphere also part of microbial habitat. Two types of microorganism can be found are autochthonous (indigenous) and allochthonous (foreign). The important physical factor in Hydrosphere is dissolved oxygen content, temperature, pH and also light penetration.

1. light - determine the rate of photosynthesis
2. temperature - determine by the latitude and weather condition, large body water will be more stable in temperature.
3. pressure - important in ocean, increases 1 atm with each 10 m in depth.
4. nutrient - varies in ocean 
5. dissolved gas - oxygen (for aerobic) & carbon dioxide (for photosynthetic process)

Here I include the video on how eutrophication can occur hope it useful.. ^_^

Salt marshes, its unlike the estuaries it lack of freshwater input from a single river. Salt marsh ecosystems can be modeled in Winogradsky columns.

Thats all from me..hehe 

week 6

Assalamualaikum and hye everyone!!!!

Now it's already week 6!! for the Monday class we study on the topic of Microbial Interactions. We finish up this topic on Monday.

This the overall and basic knowledge that we should know about every interaction around us. After finishing the lecture we have a quiz on this topic. So Dr. Wan give us 9 question and answer it on the spot.

Before we start our class on Thursday, we do a flipped classroom activities on Popplet and VoiceThread. Thanks to group 4 who provide us with this interesting learning tools for this week. Its very helpful, you can learnt and hear the lecture while doing something else like cleaning up your room or something else. They already provide us a mind map in popplet and explained it more detail in the VoiceThread.

mindmap in the popplet

Flipped classroom in VoiceThread

For the next day which is Thursday, we started new topic on Microorganism in terrestrial ecosystems. Terrestrial ecosystem also known as the Lithosphere. The most important lithosphere is the soil. Soil contained of various type of organic and inorganic components. Soil is a microbial habitat and it is a very complex and contain large variety of habitats in it. As a result microbial diversity in soils is greater than in the aquatic diversity. Soil consist of 4 different layer which is the Topsoil, subsoil, parent soil and bedrock.

The soil layer.

The soil organic Matter (SOM) is the one that would retained the soil nutrients, maintain the soil structure, helps in hold the water for plant use and the level of SOM is depending on the environment conditions and agricultural management practices. There are two categories of soil which is mineral soil and organic soil.

Physicochemical condition which would affect the microbial populations

1. surface
2. water (moisture)
3. temperature
4. acidity and alkalinity
5. soil atmosphere

After finish the lecture we must sit in a group for a group work. We must find what possible microorganism may have in the different layer of soil and submit it in the blendspace. 

Thats all.. ^_^

WEEK 5

Topic 5 : Microbial Interactions

Assalamualaikum and hello all!!!!!. 

This week we only have one class for microbial ecology.. sobs sobs~ hehe

THURSDAY, 26 March 2015....Before we start our lecturer ask us to go to the link padlet.com/zuhainis/microbeinteraction and each of us must share an information about our topic today which is the Microbial interaction. Unfortunately, me and Aina could not get the internet access therefore we borrow Aisya phone to share what we have found one microbial interaction.

This is what we share in the padlet. Its about the commensalism interaction of microorganism with host (human).

After that, we discuss about our SCL on Life Without Microbe. Its gonna be like an event in our faculty and all of us are the involve. I'm as a treasurer $_$ huhu.. This event will be held on 21th of Mei 2015. 

Continue our lecture on microbial interactions. So basically microbial interactions is about interaction of microorganism in the ecosystem and to differentiate the type of microbial interaction within the ecosystem. There are three types of microbial interaction which are endosymbiont, ectosymbiont and symbiont.

the summary of what I learnt from Thursday lecture.

We had only 15 minutes lecture but we got full of information and the overview on what we gonna learnt on the next week. That's all ^_^

WEEK 4

Topic 4 : Distribution of microorganism 

In this forth week we study on topic 4 which is the distribution of microorganism. This topic is basically about the distribution of bacteria at the places that follow their needs and have a correct nutrition for their growth. Then, we will be looking for the physical and chemical factors affecting the microbial distribution.

Growth limitation by environmental factors, there are two laws which is :

a) Liebig's Law of the Minimum

b) Shelford's Law of Tolerance

Both laws determine the presence and success of organism in an ecosystem.

Physical factors affecting distribution of microorganism

• Solutes and water activity
• Temperature
• Pressure
• Radiation

So we look one by one on the physical factors that affecting the distribution of microorganism. Solutes and water activity is about the changes in the osmotic concentration. Hypotonic solution is a solution with low osmotic concentration. Water will enter into the cell and making the cell to burst while hypertonic solution is a solution with high osmotic concentration. In this solution water will move out from the cell and making the cell shrink (plasmolysis). Amount of water available to microorganism can be reduce by interaction with solute molecules (osmotic effect) and adsorption to the surfaces of solids.

Temperature will affected the enzyme catalyze reactions. If the temperature beyond the maximum temperature of bacteria growth this the enzyme in the cell denatured and also the transport carries and other proteins also will subject to damage and disintegrate membrane. At low temperature membrane would be solidify and velocity of enzyme reaction is very low.

The pressure at the land or surface of water is 1 atm while in the deep sea the pressure is about 600 until 1100 atm (place where barotolerant will inhibit chemical reaction. Barophilic microorganism is a microorganism that dependant on high pressure. It will under go a rapid growth when in high pressure. Radiation, the major source of heat is infrared. UV radiation is the most damaging to living organisms.

Chemical factors affecting distribution of microorganisms :

• pH 
• Oxygen concentration
• water
• carbon
• nitrogen. phosphorus and sulfur
• special growth factor
• trace element

pH is the measure of hydrogen ion activity of a solution. There are four types of microorganism based on the pH tolerance which is acidophiles (pH 0 to 5.5), neutrophiles (pH 5.5 to 8.0), alkalophiles (pH 8.5 to 11.5) and extreme alkalophiles (above pH 10). We can see a few types of microorganism based on the oxygen concentration like aerobes, anaerobes, facultative anaerobes, aerotolerant anaerobes and microaerophiles. Water occupy almost 75-90% of cells. The function of water is as solvent and also for cellular function and also in metabolism.

Carbon is importance for chemical building block for cells and as source of energy for some microorganism. Special growth factors is specific nutrient such as amino acid or vitamin that was needed in low concentration. Trace element is for the enzyme to function or neede in the metabolism and it is not necessary to specifically provide. 

These are the factors that I have learnt from the lecture and because of these factors making the bacteria come to that specific place.

Thursday we have test 1. This test cover 4 topics fom the principle of microbial ecology until distribution of microorganism. After finish the test about one hour, Dr Wan give us a bit explanation about our SCL task. That's all for this week see again next week.

WEEK 2 & 3

Topic 2 : Microbial group

This second topic is about the microbial group. Basically what I learnt in this topic is about the three major form of life which is eucaryotes, procaryotes and viruses. For eucaryotic microbes, we only focus on the fungus, molds, algae and also protozoa. First of all before we started our class on Monday we had given a task to take a picture on how and what method we use to study.

this is my method of study...so I choose to do a mind map because it easier for me to memorise the keyword....hehea

So above is my mind map that I have made after study the lecture note that had been provided by my lecturer. After finish the mind map I took a picture of it and uploaded it in the edmodo.

In the monday evening Dr. Wan asked us agained to seat with group member because we gonna do another group work task. For today group work task we have to divide everyone to every topic that we have in Microbial Group and do a summarize. So I got FUNGI....

this is my summarize about fungi. 

Fungi is an eucaryote. The characteristic of fungi is multicellular and multinucleated (except yeast), fungi is a spore bearing organism and they are absorptive heterotroph and also saprophytes. Fungi did not have chlorophyll therefor they cannot be a photosynthetic organism because they cannot undergo photosynthesis. Their cell wall is made up of chitin. the primary storage of polysaccharides for fungi is glycogen. Fungi are stationary organism and they disperse by the wind, animal and water.

There are four type of fungi that we have which is chytrids ( Chytridiomycota), zygote ( Zygomycota), sac (Ascomycetes) and club (Basidiomycetes). Fungi have three types of feeding forms which is saprobic heterotrophs, parasitic heterotrophs and mutualistic heterotrophs. Saprobic heterotroph is organism that feed on dead or decaying material organic matter. Parasitic heterotroph feeding on living host at cost to the host. Lastly, mutualistic heterotroph is feeding of or with living host without damaging it and both got benefit.

This is the overall of my other group member summarize.

Oh before I forget, we do this activity in the Popplet. All of us must sign in into the popplet and one person in every group must make a new popplet page for their group and invite other group member. each group member must contribute in giving their summarize in the popplet. So above is my group popplet mind map.

That's all for today...I'm got more knowledge when I do this activities because I search and read so many new things about fungi and other organism while searching for the content for my summary...hehe


THURSDAY!!!! 4 hours lecture!!!

4 hours lecture!!..sound like crazy but actually its very relaxing and I have a lot of fun in this 4 hours lecture. Before the class start our Dr. Wan odered 'nasi lemak' for all of us. weeeeeee ^-^.. Then, all of us must connect to the wifi but unfortunately not all of us can connect because the wifi cannot support all 45 devices that we have. So, a little bit messy in the morning, our Dr call the technician to fix it.

While the technician do their job, we start our lecture on the microbial group. In this topic we focus on the microorganism ecological role.

This is all of the ecological role of the microrganism that I had learnt from the lecture.

After we have a lecture about 2 hours we took a break for 10 minutes. This is the time for us to eat the 'nasi lemak' weeeeeee... Its so delicious I like it. Thanks to Dr Wan who bought that nasi lemak' for us. I really enjoy ate it...hehea..

Start agained our lecturer on the microbial group. Then, Dr wan ask us to connect to the internet to do next task in the Quizlet. This is an individual task. I need to fill in 50 terms with its difinition and its all must be related to our next topic which is Microbial nutrition and metabolism.

this is apart of my terms in quizlet.

After done with quizlet exercise, I and all of my classmate have another task. This time it was a quiz, very interesting and fun quiz we have. I really enjoy it. My lecturer ask us to open Kahoot.com and join the quiz in the form of game. Its like a game and played it with all of the classmate. First time I played this and make me feel really nervous. I'm really had so much fun for today.


IT'S FRIDAY NOW!!!

Today is our replacement class for 2 hours. For today lecture we continued last night lecture on the microbial group. Today I study on the General consideration of microbial features . There are 5 general consideration of microbial features.

microbial features 

1) Microbial size

2) Microbial cell structure

3) Microbial cell replication

4) Cell nutrition

5) Cell behavior

After finish on the microbial group topic, then we go to another topic which is Microbial nutrition and metabolism. Focus on nutrition first, in nutrition we will learnt about diversity in nutritional requirements of microorganism. Most microbes require fewer nutrients than do large life forms. The function of nutrient requirement by a microbe is similar or identical to that of a large life form. 

terms related to temperature.

TERMS RELATED TO pH is :

-acidophiles (low pH)

-alkalinophiles (high pH)

TERMS RELATED TO LOW WATER ACTIVITY :

-osmophile (can stand hypertonic)

-xerotolerant (dry)

After we finish on the microbial nutrition lecture, we must connet to the internet and again we play kahoot.

After finish playing this game and the winner is Cheo, so end of our fun for today and for this week..hehe..hope we will play again this game next week...thats all thank you..

INTRO

WEEK 1

Assalamualaikum and hey everyone!!

This is my forth semester and this semester I have enrolled in the Microbial Ecology courses. I'm looking forward to start this semester and especially the ecology class. My lecturer for microbial ecology class is Dr. Wan Zuhainis. Unfortunately, our first class of ecology have to cancel but our lecturer have already provided a task for us. The task is we must find an article that related to the Principle of Microbial Ecology.

This is the article that I have choose.

From the article relate what you have read with the Principle of microbial ecology.

THURSDAY, ( 9-11 am)

First class of microbial ecology for this semester. In this first class Dr. Wan has give us some briefing about what we going to do and learnt this semester in this subject. We go through the learning outcome and outline. After that we have to form a group of 6 to 7 people in one group. I in the group 1 with Hidayah, Aisyah, Aina, Fareeza, Erfiana and Amalina. Then, Dr. Wan explained to us about the SCL. We have 5 five SCL to do : 3 SCL is a group work and another 2 SCL is an individual work.

That's all what I do in this first class. Thank you!!!!

WEEK 2

MONDAY, ( 4-5 pm)

Week 2 has started guys and i'm really excited. for this second week and second class of microbial ecology I have many activities in class with my group and classmate. My microbial ecology class started at 4.00 pm until 5.00 pm. In this one hour class, I have some activities with my group member. First activity : we needed to choose one of our group member article from the first task in Edmodo, read it and try to understand and relate it with the Principle of microbial ecology. We must type what we get and understand from the article in the padlet. 

 This is our reflection and what we understand about the Principle of microbial ecology based on the article that we chose. Please have a look at our group reflection (group 1) hehe

   

At the same time while read and looking for the Principle of microbial ecology, we in a group require to state what topic that we gonna do for another SCL : Live Without Microbe in padlet also. So we have decided to do a topic that related to the environmental field on the oil-degrading bacteria.

Last but not least, before the class end our lecture ask us to comment on the other group reflection on the Principle of microbial ecology based on their article. So, my group chose group 7. Have a look above on the left.

THURSDAY, ( 9-11 am)

Today is two hours class of Microbial Ecology. First of all before the lecture start my lecture Dr. Wan point a few student and she will asked a question. I'm felt very nervous at that moment (afraid if I unable to the question that she asked). After several question have been asked, now its time for the lecture. We go through the slide quickly because all of us have read the lecture note before coming to the class. 

What I have learnt from the lecture? Basically what I learnt from this lecture is about the discipline in the microbial ecology, we have 6 disciplines which is applied ecology, human/plant/animal ecology, physiological ecology, population ecology, ecotoxicology and political ecology. (but we more focus about on microbial ecology. There are 2 strategists in the microbial ecology that have been used by the microorganism which are r and k strategist. r strategist is about the reproduction. This strategist have high rate of reproduction and high growth rate while the K strategist is about the adaptation. k strategist have low reproduction rate but this strategist is more stable. the conclusion is K strategist is better than r strategist. In ecology we have two type of succession : autogenic succession and allogenic succession. End of the lecture!!

Now its the time for the group work!! huhu .. we have to sit in our group and summarize on the topic that we have learnt.(without referring to the notes oke)

tadaaaa!!! this is my group summary.

That's all what me and my classmate did in the microbial ecology class for this week. The clss end with a peace..hehe ..see again next week.
