Abstract
A novel plant-beneficial bacterium strain, designated as JGH33T, which inhibited Peronophythora litchii sporangia germination, was isolated on Reasoner's 2A medium from a litchi rhizosphere soil sample collected in Gaozhou City, Guangdong Province, PR China. Cells of strain JGH33T were Gram-stain-positive, aerobic, non-motile, bent rods. The strain grew optimally at 30-37 °C and pH 6.0-8.0. Sequence similarity analysis based on 16S rRNA genes indicated that strain JGH33T exhibited highest sequence similarity to Sinomonas albida LC13T (99.2 %). The genomic DNA G+C content of the isolate was 69.1 mol%. The genome of JGH33T was 4.7 Mbp in size with the average nucleotide identity value of 83.45 % to the most related reference strains, which is lower than the species delineation threshold of 95 %. The digital DNA-DNA hybridization of the isolate resulted in a relatedness value of 24.9 % with its closest neighbour. The predominant respiratory quinone of JGH33T was MK-9(H2). The major fatty acids were C15 : 0 anteiso (43.4 %), C16 : 0 iso (19.1 %) and C17 : 0 anteiso (19.3 %), and the featured component was C18 : 3 ω6c (1.01 %). The polar lipid composition of strain JGH33T included diphosphatidylglycerol, phosphatidylglycerol, dimannosylglyceride, phosphatidylinositol and glycolipids. On the basis of polyphasic taxonomy analyses data, strain JGH33T represents a novel species of the genus Sinomonas, for which the name Sinomonas terricola sp. nov. is proposed, with JGH33T (=JCM 35868T=GDMCC 1.3730T) as the type strain.

Abstract
A novel cellulolytic strain JC656T was isolated from the rhizosphere soil of Alisma plantago-aquatica of floating island (Phumdis) of Loktak lake, Manipur, India. The 16S rRNA gene sequence similarities between strain JC656T and other Sinomonas type strains ranged between 98.5 and 97.3%, wherein strain JC656T exhibited the highest sequence similarity (98.5%) to Sinomonas notoginsengisoli KCTC 29237T. Colonies were yellow-colored and grew aerobically. Cells were gram-positive, rod-shaped and non-motile. The optimal growth of the strain JC656T occured at 28 °C and pH 7. Strain JC656T contained MK-9 as the predominant isoprenoid quinone and anteiso-C15:0, iso-C16:0 and anteiso-C17:0 as the major fatty acids. Diphosphatidylglycerol, phosphatidylinositol, phosphatidylglycerol, phosphatidylmonomethylethanolamine and a glycolipid were the polar lipids. Strain JC656T contained lysine, alanine, glutamine, diaminopimelic acid (DAP) and two unidentified amino acids as characteristic cell wall amino acids. The genome size of strain JC656T was 3.9 Mb with a DNA G + C content of 69.9 mol %. For the affirmation of the strain's taxonomic status, a detailed phylogenomic study was done. Based on its phylogenetic position and morphological, physiological, and genomic features, strain JC656T represents a new species of the genus Sinomonas, for which we propose the name Sinomonas cellulolyticus sp. nov. The type strain JC656T = (KCTC 49339T = NBRC 114142T).

Characterization of Sinomonas gamaensis sp. nov., a Novel Soil Bacterium with Antifungal Activity against Exserohilum turcicum. Microorganisms 2019; 7:microorganisms7060170. [PMID: 31181735 PMCID: PMC6617354 DOI: 10.3390/microorganisms7060170] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2019] [Revised: 06/03/2019] [Accepted: 06/06/2019] [Indexed: 12/18/2022] Open
Abstract
A novel Gram staining positive, aerobic bacterium NEAU-HV1T that exhibits antifungal activity against Exserohilum turcicum was isolated from a soil collected from Gama, Hadjer lamis, Chad. It was grown at 10–45 °C (optimum 30 °C), pH 5–10 (optimum pH 8), and 0–4% (w/v) NaCl (optimum 1%). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain NEAU-HV1T was closely related to Sinomonas susongensis A31T (99.24% sequence similarity), Sinomonas humi MUSC 117T (98.76%), and Sinomonas albida LC13T (98.68%). The average nucleotide identity values between NEAU-HV1T and its most closely related species were 79.34−85.49%. The digital DNA–DNA hybridization values between NEAU-HV1T and S. susongensis A31T, S. albida LC13T, and S. humi MUSC 117T were 23.20, 23.50, and 22.80%, respectively, again indicating that they belonged to different taxa. The genomic DNA G+C content was 67.64 mol%. The whole cell sugars contained galactose, mannose, and rhamnose. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, and four glycolipids. The respiratory quinone system comprised MK-9(H2), MK-10(H2), and MK-8(H2). The major cellular fatty acids (>5%) were anteiso-C15:0, anteiso-C17:0, C16:0, and iso-C15:0. Based on the polyphasic analysis, it is suggested that the strain NEAU-HV1T represents a novel species of the genus Sinomonas, for which the name Sinomonas gamaensis sp. nov. is proposed. The type strain is NEAU-HV1T (= DSM 104514T = CCTCC M 2017246T).
