Question

50. Some of the halophilic microbes accumulate high concentrations of intracellular
glycerol to counterbalance the osmotic pressure from the high level of
extracellular salt. One such organism is used for microbial production of glycerol.
Choose the organism that is used for glycerol production.
Archae
A. Halobacterium halobium
B. Rhodobacter halogens
C. Dunaliella salina
D. Clostridium acetobutylicum​

Answer 1

Explanation:

In a submerged fermentation, the bacteria produce dihydroxyacetone in yields of 75–90% from a 5–15% solution of glycerol. ... Glycerol can be produced either by microbial fermentation or by chemical synthesis from petrochemical feedstocks or can be recovered as a by-product of soap manufacture from fats.
