Abstract:Pseudoalteromonas haloplanktis, a psychrotrophilic marine bacterium of biotechnological interest, shows anti-biofilm properties and is particularly relevant for cold storage of vacuum packed seafood. We focused our interest on the activation of cholesterol metabolism in this bacterium as the presence in its genome of a putative 3-ketosteroid-Δ(1) -dehydrogenase. This study reports GC-MS and LC-MS/MS profiles of sterols/steroids and their derivatives found in cell extracts of P. haloplanktis grown in a medium w… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
