abstract= A taxonomic study was carried out on strain YPA3-1-1T, which was isolated from deep-sea sediment of the Pacific Ocean. The bacterium was Gram-stain-positive, oxidase-positive, catalase-negative, rod-shaped and spore-forming. Growth was observed at salinities of 1.0–6.0 % and at temperatures of 10–40 °C. The isolate could degrade gelatin and aesculin. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain YPA3-1-1T belonged to the genus Chengkuizengella , with the highest sequence similarity to the only typespecies, Chengkuizengella sediminis J15A17T (98.5 %). The estimated average nucleotide identity and DNA–DNA hybridization values between strain YPA3-1-1T and C. sediminis J15A17T were 88.1 and 35.0 %, respectively. The cell wall of strain YPA3-1-1T contained meso-diaminopimelic acid. The principal fatty acids (>10 %) were iso-C16 : 0 (35.5 %) and anteiso-C15 : 0 (17.5 %). The G+C content of the chromosomal DNA was 33.1 mol%. The respiratory quinone was determined to be MK-7 (100 %). The polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, glycolipid and three unidentified phospholipids. The combined genotypic and phenotypic data show that strain YPA3-1-1T represents a novel species within the genus Chengkuizengella , for which the name Chengkuizengella marina sp. nov. is proposed, with the type strain YPA3-1-1T (=MCCC 1A14042T=KCTC 43019T).,
