BLG 144 Lecture Notes - Lecture 6: Anaerobic Respiration, Methionine, Aldehyde
Document Summary
Prokaryotes were the earliest living organisms (first on earth) Domain is the largest classification taxonomic level, there are 3 domains. One simple rna translation begins with formyl methionine. < results in diarrhea (gram negative bacteria) endotoxins released when bacteria die, cell walls breakdown ex: salmonella: robert koch first to demostrate causative link between bacteria and. Bacterial and viral transmission and growth is responsible for certain diseases to be. Sanitation and effective antibiotics are key developments however, prokaryotes mutate and multiply quickly, can also spread to other prokaryote species (horrizontal (lateral) gene transfer) Antibiotics resistant bacteria multiply and evolve into a resistant strain: economic and ecological importance. Fermentation: anaerobic respiration by microbes to degrade sugars/starch. Symbiotic relationships: prokaryotes can convert and breakdown compounds that other organisms cannot. Enrichment cultures: grow under specific conditions, then isolate and study. Since many bacteria cannot be grown in culture to isolate due to morphology differences, other.
