Polyphasic Characterization of Pseudomonas stutzeri CLN100 Which Simultaneously Degrades Chloro- and Methylaromatics: A New Genomovar Within the Species

Strain CLN100 was isolated after enrichment on mineral medium with chloronaphthalene as the only carbon and energy source. It was able to use simultaneously and productively chloro- and methyl- derivatives of naphthalene and salicylate through a chromosomally encoded meta pathway. Phenotypic, chemotaxonomic and genotypic characterization classified strain CLN100 as a member of the species Pseudomonas stutzeri. DNA-DNA hybridizations, 16S rDNA, gyrB, rpoD sequences, and molecular fingerprinting indicate that strain CLN100 is a representative of a new genomovar (genomovar 10) within the species.
