Can't really remember what I reflected in the second class because I didn't write it down at once. After a week, most memory has faded away, that's the limit of human mind, memory will not last forever if we are not refreshing them constantly. Luckily, I've jotted down the lessons learnt, so that I didn't forgot everything during the second lesson.
Lessons learnt :
Lessons learnt :
Species of microbes
- Bacteria
- Clostridium botulinum (Gram-positive, rod-shaped, anaerobic, spore-forming, motile)
- able to produce neurotoxin botulinum, which caused flaccid paralytic (like those in botox)
- lethal dose : less than 1 μg in humans
- found in cosmetic products and contaminated canned food
- release alpha toxin (Clostridium perfringens)
- Lactobacillus
- Lactococcus
- Nitrosomonas , nitrospiral, nitrogen-fixation
- Streptomyces griseus
- produce Streptomycin
- Archaea
- Algae
- Fungi
- Penicillin
- produce Penicillium (fungus vs. bacteria)
- Protozoa
- Biofilm
- Human microbiome
- Normal flora
- Alpha toxin (released by Clostridium perfringens)
- Afla toxin (released by fungus)
- Zooglea
- "Phylologists"
- Algae has silica cell wall ; fungi has chitin cell wall
- Fungi can recycle waste. It is not motile. It has hyphae & mycelium to penetrate into soil, which makes the soil conducive for bacteria to live (mutualism & microbiointeration)
- Human skin has pH value of 5.5
- Difference between microbiome and microbiota
- BT kill insects?
- bioremediation? oil spill done by studying the bacteria that survive in the condition
