Numerical Taxonomy of the Genus Pseudomonas from Milk and Milk Products

Department of Microbiology, University of Guelph, Guelph, Canada

ABSTRACT

Six hundred and fifty-three alkaligenic and psychrophilic organisms were isolated from 136 samples of milk and milk products, and 182 belonged to the genus Pseudomonas. The Pseudomonas, with 16 known species, were further classified into four groups for 97 features by Adansonian's classification. By S values Group I comprised 98 cultures identified as P. fluoresceins and "psychrophilic P. aeru-ginosa-like" organisms. Group II consisted of 80 cultures, with fluorescents characterized as P. putida species, with an intermediate group between P. putida and P. fluorescens. The nonfluorescents were related to P. fragi and P. putrefaciens. Group III had only 15 cultures which could not be associated with any group or species. Group IV comprised 5 cultures which were related to P. alkaligenes. The known type species, members of Groups III and IV, by S and M comparisons were markedly dissimilar.
