 Today we have a long class from 8.30 am to 12.00 am. We learn about Algae and Fungi.
 
Algae is in the Protist group.Most of the algae are photoautototropic and require water.Algae reproduce through asexual and sexual reproduction. One of example of algae is seaweed. Seaweed provide habitat for marine communities.
 
Algal bloom happen when eutrophication, too much substrate high nutrition. This can be observed by discoloration of water. The toxin produce by algae can effect human if ingest through fish. Algae bloom also can happen in swimming pool if no chlorine is added. If algae bloom happen it means that the lake is polluted. Before this I never thought that if the lake turn to green it means it is polluted and have toxin. I thought it was good things to happen that show the organism in the lake is in good condition but now I know I wrong. Learning about Algae bloom make now realise why no people go fishing when the lake is very green.
 
Slime Molds
Slime Molds resemble fungi in appearance and live style.There are three division of slime molds
  • Myxomycota (Plasmodial slime molds)
  • Acrasiomycota (Cellular slime molds)
  • Peronosporomycetes (water molds)
Before learning fungi we have to do crossword from LMS or Edmodo.

Fungi is spore bearing organism. Fungi do not contain chlorophyll.  Fungi has rigid cell wall made up of chitin. Fungi can be kill by Protozoa call vampyrellids which make hole on fungi and suck the nutrient.
The disease cause by fungi is call mycosis. Sporothrix cause subcutaneous mycosis
Basidiomycota is one of the phylum of fungi. One of the example is toadstools, most toxin mushroom.
Amanita also very toxin mushroom although it is very beautiful mushroom. If have eaten the mushroom have to eat charcoal to reduce the toxin. If too bad, doctor have to pump our stomach.
 
Before class end we do crossword on Fungi and after that we eat chocolate cake bring by Dr Wan.

What I have learn:
-Algae can reproduce asexually and sexually
-Fungi do not has chlorophyll
-If food have been infected by fungi have to throw the food
-The disease of fungi is classified through first organ penetrated by fungi.

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.
