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

What I have learn

          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 ...
