Tolerance of an Antarctic Bacterium to Multiple Environmental Stressors

Current Microbiology, 2015
A population of cold-tolerant Antarctic bacteria was screened for their ability to tolerate other environmental stress factors. Besides low temperature, they were predominantly found to be tolerant to alkali. Attempt was also made to postulate a genetic basis of their multistress-tolerance.

Extracellular protease from Bacillus coagulans, a psychrotrophic, Antarctic bacterium

World Journal of Microbiology & Biotechnology, 1994
Bacillus coagulans, when grown on casein at 20°C, produced an inducible, metalloprotease of 28 kDa at 1.6 U/mg cell protein. (NH4)2SO4 at 2 g/l decreased enzyme production irrespective of carbon source.
