Geographical divergence of Trimethylamine N-oxide demethylase function in Shewanella baltica
Several strains of Shewanella baltica were isolated from large-scale yellow croaker farms in Ningde (ND), in southern China, and in Yantai (YT), in northern China. Putrefaction testing revealed that the YT strain was strongly putrefactive, whereas the ND strain exhibited weak putrefactive properties. Whole-genome sequencing of representative strains revealed a pan-genome that is open and capable of enhancing environmental adaptability through horizontal gene transfer.
