Microbes in Human Welfare Test - 3

Pseudomonas denitrificans is the highest yielding organism for cyanocobalamin. It yields 60 mg/lit of cyanocobalamin.

None of the species of Bacillus is used for making harzer cheese. Staphylococcus saphrophyticus is a coccus bacterium used for making harzer cheese. Bacillus sphaericus is exploited in stinky tofu. Bacillus cereus, B. coagulans and several other Bacillus sps are exploited in chocolate production. Natto is a traditional Japanese food made from soybeans fermented with Bacillus subtilis var. natto.

Acetone–butanol–ethanol (ABE) fermentation is a process that uses bacterial fermentation to produce acetone, n-Butanol, and ethanol from carbohydrates such as starch and glucose. Acetone/butanol fermentation is carried out by microbes of the genus Clostridium.Riboflavin is a major by-product which is found in the dried biomass.

Benzyl penicillin is penicillin G. Penicillin G binds to and inactivates the penicillin-binding proteins (PBPs) located inside the bacterial cell wall.

Leuconostoc mesenteroides is a heterofermentative organism used for the production of lactic acid. It also produces CO2, ethanol and acetic acid.

Thermomonospora, a bacterium isolated from compost, has an optimum temperature of 53 degree Celsius for growth. It is a preferred organism for the production of alpha-amylase, as it produces thermostable enzyme.

Ashbya gossypii is used for the production of riboflavin. This organism is pathogenic to a very large number of plants like cotton, tomato, soybean, and cabbage.

Acetobacter suboxydans carries out conversion of D-sorbitol to L-sorbose. Reduction of one molecule of NAD takes place.

Microbacterium ammoniaphilum is utilised for the production of DL-alanine. Immobilised E. coli cells with good activity of aspartase are used for aspartate production. Mutant strain of C. glutamicum and Brevibacterium flavum are used for L-lysine production. Corynebacterium glutamicum is used for glutamine production.

Candida utilis uses lactose as a carbon source for the production of ethanol using whey media.
Candida pseudotropicalis uses sulphate-waste liquor and Saccharomyces carlsbergensis uses starch or sugar for the production of ethanol. Saccharomyces cerevisiae uses starch or sugar as a carbon source.
