Enterobacter soli sp. nov.: a lignin-degrading γ-proteobacteria isolated from soil.

ABSTRACT

A Gram-negative bacterium that formed cream-colored colonies designated strain LF7 was isolated from soil collected in the Tambopata National Reserve in Madre de Dios, Peru. 16S rRNA sequence comparisons indicate that LF7 is a novel Enterobacter sp. closely related to E. asburiae JCM 6051(T) [AB004744] and E. aerogenes JCM 1235(T) [AB004750] based on their sequence homologies (p-distance 1.06 and 1.19%, respectively). DNA G + C content was 52.8 mol% which is within the range reported for E. asburiae (55-57 mol%). The major cellular fatty acids present in the LF7 strain were C(160) (27.3%), C(161) ω7c and/or C(161) ω6c (16.3%), C(181) ω7c (16.1%), C(170) cyclo (12.4%), C(140) 3-OH and/or C(161) iso-I (8.9%), C(140) (7.6%), C(120) (3.9%), C(170) (2.4%), C(130) 3-OH and/or C(151) iso-H (1.7%), C(130) (1.1%), and C(182) ω6,9c and/or C(180) ante (0.5%). The cellular fatty acid profile, G + C content, phenotypic and biochemical characteristics were consistent with its placement in the genus Enterobacter. The name Enterobacter soli is proposed for this bacterium.
