Abstract
A Gram-stain-negative bacterial strain, designated as E165T, was isolated from a tidal flat sediment of the East China Sea. Strain E165T grew optimally at pH 6, at 32 °C and with 1–2 % (w/v) NaCl. The 16S rRNA gene sequence similarity results revealed that strain E165T was most closely related to
Marinomonas rhizomae
IVIA-Po-145T,
Marinomonas polaris
CK13T,
Marinomonas foliarum
IVIA-Po-155T,
Marinomonas hwangdonensis
HDW-15T,
Marinomonas pontica
46-16T,
Marinomonas mangrovi
B20-1T and
Marinomonas shanghaiensis
DSL-35T with values of 97.0–98.5 %. The digital DNA–DNA hybridization and average nucleotide identity values between strain E165T and the reference strains were 21.9–34.3 % and 77.6–87.3 %, respectively. The DNA G+C content of the isolate was 42.9 mol%. Strain E165T contained Q-8 as the sole ubiquinone and C16 : 0, summed feature 8 (C18 : 1
ω7c and/or C18 : 1
ω6c) and summed feature 3 (C16 : 1
ω7c and/or C16 : 1
ω6c) as the major fatty acids. The major polar lipids of strain E165T were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, aminolipid and aminophospholipid. On the basis of phenotypic characteristics, phylogenetic analysis and DNA–DNA relatedness, a novel species, Marinomonas lutimaris sp. nov., is proposed with E165T (=MCCC 1K06241T=KCTC 82809T) as the type strain.

Adaptation Potential of Three Psychrotolerant Aquatic Bacteria in the Pan-Okhotsk Region. WATER 2022. [DOI: 10.3390/w14071107] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 02/04/2023]
Abstract
The Pan-Okhotsk region, which is part of the western North Pacific Ocean, is famous for its active volcanoes, which are part of the Pacific Ring of Fire and that enrich the surrounding waters with essential chemicals. Therefore, this region, including the Sea of Okhotsk and the Sea of Japan, is characterized by rich biota. Bacterioplankton plays a significant part in biological communities and is an indicator of ecosystem function. Analyzing the adaptability of three representatives of the microbiota of the Pan-Okhotsk region was the goal of our investigation. Marinomonas primoryensis KMM3633T (MP), Yersinia ruckeri KMM821 (YR), and Yersinia pseudotuberculosis 598 (YP) from the G.B. Elyakov Pacific Institute of Bioorganic Chemistry were studied by means of genomic and bioinformatic methods. The list of membrane translocator proteins, metabolism pathways, and cold shock and antifreeze proteins that were revealed in the genome of MP characterized this bacterium as being adaptable to free living in marine conditions, even at winter temperatures. The genomic potential of YR and YP makes not only survival in the environment of the Pan-Okhotsk region but also pathogenesis in eukaryotic organisms possible. The data obtained will serve as a basis for further ecosystem monitoring with the help of microbiota research.

Abstract
Two novel Gram-stain-negative, facultative anaerobic, non-flagellated, rod-shaped bacterial strains, designated MT13T and MT32, were isolated from sediment samples collected from the Mariana Trench at a depth of 8300 m. The two strains grew at −2–30 °C (optimum, 25 °C), at pH 5.5–10.0 (optimum, pH 7.5–8.0) and with 0–15 % (w/v) NaCl (optimum, 3–6 %). They did not reduce nitrate to nitrite nor hydrolyse Tweens 40 and 80, aesculin, casein, starch and DNA. The genomic G+C contents of draft genomes of strain MT13T and MT32 were 52.2 and 54.1 m ol%, respectively. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strains MT13T and MT32 were affiliated with the genus
Halomonas
, with the highest similarity to the type strain of
Halomonas olivaria
. The values of average nucleotide identity and in silico DNA–DNA hybridization between strain MT13T and MT32, and between strain MT13T and five closely related type strains of
Halomonas
species indicated that strains MT13T and MT32 belonged to the same species, but represented a novel species in the genus of
Halomonas
. The major cellular fatty acids of strains MT13T and MT32 were C16 : 0, summed feature 3(C16 : 1
ω7c/ω6c) and summed feature 8 (C18 : 1
ω7c/ω6c). Major polar lipids of strains MT13T and MT32 included phosphatidylglycerol, phosphatidylethanolamine and diphosphatidylglycerol. Ubiquinone-9 was the predominant respiratory quinone. Based on data from the present polyphasic study, strains MT13T and MT32 represent a novel species of the genus
Halomonas
, for which the name Halomonas profundi sp. nov. is proposed. The type strain is MT13T (=MCCC 1K06389T=KCTC 82923T).
