Abstract

A Gram-negative, deep brown-pigmented Gammaproteobacteria, strain IPL-1(T), capable of oxidizing indole was isolated from a lindane-contaminated site and subjected to a polyphasic taxonomic study. Most of the physiological and biochemical properties, major fatty acids (C(18:1)omega7c, C(16:1)omega7c/iso C(15:0) 2OH and C(16:0)), estimated DNA G+C content (67.2mol%) and 16S rRNA gene sequence analysis showed that strain IPL-1(T) belonged to the genus Pseudomonas. Strain IPL-1(T) exhibited highest 16S rRNA gene sequence similarity with Pseudomonas pseudoalcaligenes (99.0%), followed by Pseudomonas alcaliphila (98.7%), Pseudomonas oleovorans (98.3%), Pseudomonas nitroreducens (98.0%), Pseudomonas mendocina (97.6%) and Pseudomonas stutzeri (97.4%). However, the DNA-DNA relatedness values between strain IPL-1(T) and the closely related taxa were between 22% and 61%. On the basis of differential phenotypic characteristics and genotypic distinctiveness, strain IPL-1(T) should be classified within the genus Pseudomonas as a novel species, for which the name Pseudomonas indoloxydans is proposed. The type strain is IPL-1(T) (=MTCC 8062(T)=JCM 14246(T)).
