Pseudomonas classification

Abstract
Various criteria that have been used in the development of a system of classification ofPseudomonas species, as well as in the precise circumscription of the genus on phenotypic and molecular bases, are discussed.Pseudomonas taxonomy has transcended its own limits by suggesting a general strategy for the definition of taxonomic hierarchies at and above the genus level. A selection of studies on the biochemical and physiological properties of members of the genus is critically examined in relation to the current taxonomic scheme as a frame of reference.
