Study Notes
Vitamins and Microorganisms
- Lactic acid bacteria increase the quantity of Vitamin-B12 when milk is converted into curd.
Fermentation
- Carbon dioxide (CO2) is the reason for the rise of fermented flour.
- Yeast is the fungus that converts sugar into alcohol.
Antibiotics
- Penicillin was the first discovered antibiotic.
- Alexander Fleming discovered penicillin.
- Streptomycin and Terramycin antibiotics are obtained from bacteria.
- Streptomyces rimosus is the source of Terramycin.
Other Bioactive Substances
- Statin reduces cholesterol in the blood.
- Cyclosporin-A dissolves blood clots.
- Streptokinase dissolves blood clots.
- Lipase is used to remove oily stains.
Enzyme Sources
- Bacteria, Microthecium verrucaria and Aspergillus niger are all sources of cellulose.
Waste Water Treatment
- Physical processes are the primary treatment of wastewater.
- The residue after biogas production from dung is used as fertilizer.
Bioremediation and Biopesticides
- Bacillus brown (likely Bacillus subtilis) is involved in petroleum production.
- Bacillus thuringiensis produces Bt toxin.
- Bacillus thuringiensis is a biopesticide.
- Baculoviruses, Entomophthora and Microsporidia are all organisms used for pest control.
Biocontrol
- Trichoderma fungus is used for biocontrol of plant diseases.
Nitrogen Fixation
- Rhizobium live in symbiosis with plants and are found in the roots of legumes, specifically Rhizobium leguminosarum.
- Azospirillum and Pseudomonas fix atmospheric nitrogen.
- Anabaena is a Nitrogen fixing cyanobacteria.
