We do a quiz about prokaryotes today.This quiz was answered in group.There are only four group that participate in this quiz because there are many student that are absent today so all the student that present is divided into four group.This quiz help me to remember back what I have learn last semester and also applied the knowledge that I have learn on the question that we have not study yet.

What I have learn:
-Strong enzyme need to degrade envelope
-The component of envelope is different for gram negative and positive bacteria and archae.
-Chitin responsible for asma in human.

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
