Abstract
Rough colony type mutant was obtained from an isolate, S 6914-1 of Pseudomonas mori. The cells of the mutant grew as long filaments, being 200μm in length. No difference was observed in the mutant and the wild type on main physiological characteristics, pathogenicity, agglutination reaction and lysotype. The isolate, S 6914-1 differed from the other on properties, such as non-motility, non-flagellated, and chemical characteristics on hydrolyzation of arbutin.
