 We continue previous chapter.
Culture medium- nutrient prepared for the growth of microorganisms in a laboratory.
inoculum- microbes that are introduced into a culture medium to initiate grow.
Types of culture media

  • chemically defined-chemical composition known
  • complex media-chemical composition unknown
Selective media -contain agents inhibit growth of certain bacteria while permitting growth of others
Differential media-contain indicator that react differently with different organism.
Enrichment media-increase small numbers of desired bacteria to detectable level
blood agar

Eosin Methylene Blue Agar

I never thought that agar can change the colour according to the microbe.Before this I thought the colour of the agar will remain the same.
Measurement of microbial Growth
-Direct measurement
-plate count
There are many ways of measure microbial growth before this I thought just assume how big the colony without very specific.

What I have learn:
-culture medium-medium prepare for microbes to growth in laboratory
Liquid medium -components dissolved in water and sterilized
-Plate count perform serial dilutions of sample

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.
