Psychrophilicity of Gram‐positive bacterium, Bacillus psychrosaccharolyticus was investigated in a proteomic approach. One hundred and thirty‐one protein spots were analyzed by electrospray ionization‐quadrupole‐time of flight‐tandem mass spectrometry and identified using an unpublished translated contig database as well as a nonredundant Gram‐positive bacteria protein database from NCBI because of the lack of a genome sequence of this organism. Results focused on proteomic behavior of cold‐response show that global up‐regulation of metabolic functions and protective mechanism by stress responses might play a major role in psychrophilicity of B. psychrosaccharolyticus .
