Microbes in Human Welfare: 5 Must-Know Facts

Swiss cheese holes = Propionibacterium shermanii (CO2), NOT Lactobacillus (curd) or Penicillium roqueforti (Roquefort cheese).
Streptokinase = Streptococcus = clot-buster enzyme, NOT an antibiotic; Lovastatin = Monascus purpureus = inhibits HMG-CoA reductase.
BOD: High BOD = High pollution; secondary (biological) treatment reduces BOD via aerobic microbes in aeration tanks; methanogens produce biogas in anaerobic digesters.
Biofertilizer nitrogen fixers: Rhizobium $\frac{legumes}{symbiotic}$ , Azotobacter/Azospirillum (free-living), Anabaena/Nostoc $\frac{paddy}{cyanobacteria}$ ; Glomus (mycorrhiza) enhances phosphorus only.
Bt = Bacillus thuringiensis = Cry proteins toxic to lepidopteran larvae; Cyclosporin A = Trichoderma polysporum = immunosuppressant for organ transplants.
