My name is Sajidah.Currently study in major of microbiology in UPM.Microbiology is y first choice for degree I hope to be the unusual microbiologist.Hope to learn more about microbes.

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 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

relate Microbial Ecology to other microbiology courses have covered and apply the knowledge in the future

 In previous subject I learn  their characteristics and uses. When I am studying Microbial ecology I get to know more about the place that I learn their characteristics  and uses. I also study lab of microbiology with the knowledge from both course I should be able to know how to find and isolate microbes. Different microbes stay in different places. Different microbes require different way to isolate them. For the future application, I think to solve a problems using microbes, the microbes that will solve the problems need to be find in the problems occur. For example, bacteria that involve in bio remediation usually live and isolated in polluted area since there are able to withstands the pollutants.
