TAXONOMY OF GENUS PSEUDOMONAS WITH SPECIAL REFERENCE TO THEIR MODES OF METABOLISM OF CARBON COMPOUNDS

[摘要] Using 28 species and 202 strains belonging to the genus Pseudomonas, comparative studies were made of the capacity of utilizing various organic compounds, of metabolizing carbohydrate under aerobic and anaerobic conditions, of oxidizing gluconate, of producing acetylmethyl carbinol, etc. By and large, the metabolic features were found to be closely correlated to the pigmentation characteristics of the organisms, according to which the present authors have classified the genus Pseudomonas into three groups: namely fluorescent group, achromogenic group and chromogenic group. Nearly all the strains known as oxidative bacteria such as Ps. aeruginosa, Ps. ovalis, and Ps. schuylkilliensis were found to belong to the fluorescent group, while the strains belonging to the other two groups are generally poor in oxidative activities.
