We learn about intracellular structures of prokaryotes as third topic. We are divided into few group for going to an organelle for Awesome Microbe Carnival.This involving making 3D poster which I have never been heard before this but as soon Dr Wan show the example it is quite interesting.For our group we got nucleoid. When learning this topic we were also asked to do a presentation about gas vesicles and lipid inclusions as peer teaching. Lipid inclusions Depends on the size of cell.I wonder how to measure the how big lipid inclusions?Lipid inclusions also known as fat droplet.Lipid inclusions can only be reveal by sudan dyes.The storage material is polymer poly –β-hydroxybutyric acid. from:http://nptel.ac.in/courses/102103015/module2/lec2/images/4.png Gas vacuole Hollow structure made of protein that are membrane bounded.Impermeable to liquid. What I have learn: Lipid inclusions also known as lipid droplet Magnetosome protect cell from hydrogen peroxide acc

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 

This is the third semester. We started with the first chapter that is introduction to Prokaryotes. Prokaryotes are organism that lack nucleus or other membrane bound organelles .Prokaryotes only have two domain that are Bacteria and Archaea . Proteobacteria is the largest division of bacteria. We are divided to few group to collect information about each class in proteobacteria. Our group have to do about acidobacteria which a newly devised phylum. They can be found abundant in soil. Most of them are gram negative, resistant to desiccation and sensitive to damage by oxygen species. They live in highly acidic condition. One of the member  Candidatus Chloracidobacterium (Cab.) thermophilum is found in Yellowstone National Park are claim  to have 250000 chlorophyll and live in alkaline microbial mat compare to another members.I wonder how this organism can survive in alkaline condition? from:http://image.wikifoundry.com/image/1/v7aG6X9LOFKFkQxXHvbI0g32999/GW330H240 When collec
