TAXONOMIC STUDY ON OBLIGATELY PSYCHROPHILIC BACTERIA ISOLATED FROM ANTARCTICA

Abstract

Strains (9) of obligately psychrophilic bacteria, which were isolated from regions near Showa Station in Antarctica, were studied taxonomically. These strains were identified as Curtobacterium psychrophilum sp. nov. (1 strain), Cytophaga antarctica sp. nov. (3 strains), C. xantha sp. nov. (1 strain), Spirillum pleomorphum sp. nov. (2 strains), Micrococcus cryophilus McLean, Sulzbacker and Mudd, and Pseudomonas putrefaciens (Derby and Hammer) Long and Hammer (1 strain).
