sp. nov., isolated from deep-sea water of the Indian Ocean Free

Abstract

A taxonomic study was carried out on strain CIC4N-9, which was isolated from deep-sea water of the Indian Ocean. The bacterium was Gram-stain-negative, catalase- and oxidase-positive, rod-shaped and non-motile. Growth was observed at salinities of 0–9% and at temperatures of 4–41 °C. The isolate was able to degrade gelatin but not aesculin. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain CIC4N-9 belonged to the genus , with the highest sequence similarity to the only recognized species, D1-19 (96.9 %). The average nucleotide identity and estimated DNA–DNA hybridization values between strain CIC4N-9 and D1-19 were 80.4 and 23.0 %, respectively. The principal fatty acids were summed feature 8 (C 7 and/or C 6), C, Cω7 11-methyl, C and C. The G+C content of the chromosomal DNA was 66.8 mol%. The sole respiratory quinone was determined to be Q-10. Phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, two unknown phospholipids, four unknown aminolipids and one unknown polar lipid were present. The combined genotypic and phenotypic data show that strain CIC4N-9 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is CIC4N-9 (=MCCC 1A01225=KCTC 52336).
