Abstract
A novel Antibiotic SB-72310 is produced by cultivating a microorganism belonging to the genus Pseudomonas and being capable of producing Antibiotic SB-72310 in a culture medium to have Antibiotic SB-72310 elaborated and accumulated in the cultured broth and recovering the antibiotic. Antibiotic SB-72310 is useful as a germicide or disinfectant.
