Abstract

Pseudomonas mephitica CCUG 2513(T) has been reinvestigated to clarify its taxonomic position. 16S rRNA gene sequence comparisons demonstrated that this strain clusters phylogenetically closely with Janthinobacterium lividum (99.8% sequence similarity to the type strain). Investigation of fatty acid patterns, polar lipid profiles, polyamine patterns and quinone systems supported this delineation. Substrate utilization profiles and biochemical characteristics displayed no differences from the type strain of J. lividum, CCUG 2344(T). Therefore, the reclassification of Pseudomonas mephitica as a later heterotypic synonym of Janthinobacterium lividum is proposed, based upon the estimated phylogenetic position derived from 16S rRNA gene sequence data and chemotaxonomic and biochemical data.
