Physiological and genomic features of Paraoceanicella profunda gen. nov., sp. nov., a novel piezophile isolated from deep seawater of the Mariana Trench.

ABSTRACT: A novel piezophilic alphaproteobacterium, strain D4M1^T , was isolated from deep seawater of the Mariana Trench. 16S rRNA gene analysis showed that strain D4M1^T was most closely related to Oceanicella actignis PRQ-67^T (94.2%), Oceanibium sediminis O448^T (94.2%), and Thioclava electrotropha ElOx9^T (94.1%). Phylogenetic analyses based on both 16S rRNA gene and genome sequences showed that strain D4M1^T formed an independent monophyletic branch paralleled with the genus Oceanicella in the family Rhodobacteraceae. Cells were Gram-stain-negative, aerobic short rods, and grew optimally at 37°C, pH 6.5, and 3.0% (w/v) NaCl. Strain D4M1^T was piezophilic with the optimum pressure of 10 MPa. The principal fatty acids were C
