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 30-37â°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 (99.2â%). The genomic DNA G+C content of the isolate was 69.1âmol%. The genome of JGH33T was 4.7 Mbp in size with the average nucleotide identity value of 83.45â% to the most related reference strains, which is lower than the species delineation threshold of 95â%. The digital DNA-DNA hybridization of the isolate resulted in a relatedness value of 24.9â% with its closest neighbour. The predominant respiratory quinone of JGH33T was MK-9(H2). The major fatty acids were C15ââ0 anteiso (43.4â%), C16ââ0 iso (19.1â%) and C17ââ0 anteiso (19.3â%), and the featured component was C18ââ3 ω6c (1.01â%). 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.
