Enterobacter soli sp nov.: A Lignin-Degrading γ-Proteobacteria Isolated from Soil

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-16:0 (27.3%), C-16:1 omega 7c and/or C-16:1 omega 6c (16.3%), C-18:1 omega 7c (16.1%), C-17:0 cyclo (12.4%), C-14:0 3-OH and/or C-16:1 iso-I (8.9%), C-14:0 (7.6%), C-12:0 (3.9%), C-17:0 (2.4%), C-13:0 3-OH and/or C-15:1 iso-H (1.7%), C-13:0 (1.1%), and C-18:2 omega 6,9c and/or C-18:0 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.
