Crystal structure and functional characterization of a cold-active acetyl xylan esterase (PbAcE) from psychrophilic soil microbe Paenibacillus sp. [PDF]

PLoS ONE, 2018
Cold-active acetyl xylan esterases allow for reduced bioreactor heating costs in bioenergy production. Here, we isolated and characterized a cold-active acetyl xylan esterase (PbAcE) from the psychrophilic soil microbe Paenibacillus sp. R4.

Beta-galactosidase activity in psychrotrophic microorganisms and their potential use in food industry

Czech Journal of Food Sciences, 2002
Twenty-one psychrotrophic resp. psychrophilic bacterial strains were screened for presence of b-galactosidase activity which showed 8 of them. b-Galactosidase activity of these strains was determined for 2 substrates - synthetic substrate (ONPG) and ...

Functional Metagenomics Approach for Discovery of Novel Cold-Active Protease from the Antarctic Region

International Islamic University Malaysia Engineering Journal
The structural complexity of bacterial life makes most of it impossible to culture. Functional metagenomics approaches overcome the limitations of a culture-based approach in exploring and assessing the genetic materials of uncultured microbes.
