Aquibium pacificus sp. nov., a Novel Mixotrophic Bacterium from Bathypelagic Seawater in the Western Pacific Ocean.

ABSTRACT: A novel Gram-stain-negative, facultatively anaerobic, and mixotrophic bacterium, designated as strain LZ166^T, was isolated from the bathypelagic seawater in the western Pacific Ocean. The cells were short rod-shaped, oxidase- and catalase-positive, and motile by means of lateral flagella. The growth of strain LZ166^T was observed at 10-45 °C (optimum 34-37 °C), at pH 5-10 (optimum 6-8), and in the presence of 0-5% NaCl (optimum 1-3%). A phylogenetic analysis based on the 16S rRNA gene showed that strain LZ166^T shared the highest similarity (98.58%) with Aquibium oceanicum B7^T and formed a distinct branch within the Aquibium genus. The genomic characterization, including average nucleotide identity (ANI, 90.73-76.79%), average amino i
