Today we continue learning about Bacteria.The lesson continue from where we end last week.
We study about Gram negative bacteria with cell wall.Some of them are non phototrophic which not pathogenic such as Pseudomonas sp. that degrade complex organic molecules in soil.This microbe is important for plant growth.I wonder will the plant able to grow if this microbes are absent?
There are also Phototrophic gram negative bacteria with cell wall that are Anoxygenic  and oxygenic.Example of Anoxygenic bacteria is Rhodospirillum that can be found in water and also known as purple non sulphur bacteria.Anoxygenic bacteria do not have chlorophyll but have bacteriachlorophyll
Next category is gram positive bacteria with cell walls that contain 6 groups.One of the group is Mycobacteria. Mycobacteria tubercolosis is one of the example.This bacteria become interesting to know more because there are attemps to revive this bacteria from 300 old human mummies due to M. tuberculosis can withstand harsh condition. I wonder how the research being carry out.How was the mummies was selected?Is there are any category?

The lesson continue with presentation of Archaea.After the presentation we have to find answer for questions in slide from journal.This activity have made me know the way to search for journal and how to search even the related journal to get more information.

What I have learn:
-Pseudomonas sp. help digesting organic complex molecule.  
-Mycobacteria is in the category of gram positive bacteria with cell wall.
-learn how to find journal

The second chapter we learn about cell wall and membrane structure of prokaryote. Flagella is long filamentous appendages that propel bacteria. from: http://i0.wp.com/microbeonline.com/wp-content/uploads/2013/04/flagellar-arrangement-of-bacteria.jpg I wonder if the number and arrangement effect the movement? There are three basic part Filament hook basal body Axial filament are bundles of fibrils that arise at the end of cell beneath the outer sheath.Present in spirochetes group of bacteria What I have learn: Gram negative cell wall have few layer of peptidoglycan Gram positive have teichoic acid. Archaea have pseudomurein

26/9/14  Today we have our class at 8 o'clock early than the usual. We learn about External structure of prokaryote. I  a little bit shock when knowing we going to learn about external structure of prokaryote because we just send our mind map about internal structure of prokaryote. Anyway the class carry on and I have fun learning about external structure of prokaryote.   Prokaryotes are a group of organisms that lack of cell nucleus or any other membrane bound organelle. The two domains in prokaryote are bacteria and archaea. Three basic shapes coccus Arrangement : diplococci, staphylococci, streptococci, tetrads, sarcinae pic from:http://images.books24x7.com/bookimages/id_20695/fig153_01.jpg   Bacillus Arrangement: diplobacilli and streptobacilli   Spiral arrangement:vibrio, spirilium and spirochetes The smallest bacteria is mycoplasma. Vibrio cholera cause cholera which  cause watery diarrhea and vomiting. This bacteria comes from water contaminated by

          The first chapter of microbial ecology is The principles of ecology. When learning this chapter, I just realized that ecology is a big subject that has many principles and disciplines. I also learn about strategist microbes used that is r and k. r strategist has high reproductive rates while k strategist is more to adaptation. Another important aspect covered is homeostasis. Autotrophic succession happen when P:R> 1. P stands for photosynthesis, while R is respiration. Autotrophic succession cause accumulation of biomass. When P:R< 1, the situation is known as heterotrophic succession where consumption of organic matter is more than the production.   When studying next topic,Microbial Group and Microbial Nutrition Metabolism it is a  bit repetition on what we have learn before this. In microbial group  I discover  few microbes on certain habitat based on their microbial group.While in Microbial Nutrition Metabolism I learn that their metabolism can be studied to be a
