AN ATTEMPT AT GROUPING OF THE GENUS PSEUDOMONAS

Abstract

Taxonomical studies on the genus Pseudomonas were carried out with 28 species and 202 strains, including those obtained from several type culture collections as well as those isolated from various sources by the authors. The cultural, biochemical, physiological and ecological properties of these organisms were found to be more or less closely correlated to the characteristics of pigmentation. In respect to the pigmentation characteristics, distinction was made of three groups which were named: Fluorescent group, Achromogenic group and Chromogenic group.
