Abstract
DMSP is present in the marine environment, produced in large quantities by marine phytoplankton as an osmoprotectant, and is an important component of the global geochemical sulfur cycle. This algal osmolyte has not been previously investigated for its role in marine heterotrophic bacterial osmotic stress response. Vibrionaceae species are marine species, many of which are halophiles exemplified by V. parahaemolyticus , a species that possesses at least six transporters for the uptake of osmolytes.
