Na + , K + , and Nonspecific Solute Requirements for Induction and Function of Galactose Active Transport in an Antarctic Psychrophilic Marine Bacterium
An Antarctic psychrophilic marine Vibrio sp., with the inducible ability to accumulate non-metabolizable [ 14 C]methyl-β- d -thiogalactoside through a galactose transport system, was isolated. Induction of [ 14 C]methyl-β- d -thiogalactoside uptake was found to have a specific Na + requirement which...
