A Gram stain-positive, rod-shaped and motile bacterium, designated SYSU G01003T was isolated from a sediment sample collected from tepid spring in Tengchong, Yunnan province, southwestern China. Growth observed at temperature ranging 28–37 °C (optimum 37 °C) and pH 6.0–8.0 (optimum pH 7.0). Tolerance to NaCl was up to 2.5% (w/v) (optimal in the absence of NaCl). The cell wall peptidoglycan is meso-2,6-diaminopimelic acid and MK-7 as the only respiratory quinone. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and unidentified aminophospholipid, phospholipid, and polar lipid. The major fatty acids are C16:0, anteiso-C15:0 and C14:0. The genomic DNA G + C content of the type strain was 54.0 mol%. The average nucleotide identity (ANIb and ANIm) values between SYSU G01003T and Paenibacillus azotifigens LMG 29963T were below the cut-off level (95–96%) recommended as the average nucleotide identity (ANI) criterion for interspecies identity. Based on the above results strain SYSU G01003T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus yunnanensis sp. nov. is proposed. The type strain, SYSU G01003T (=KCTC 43132T = CGMCC 1.17384T). [ABSTRACT FROM AUTHOR]

One motile strain designated, YIM DR1026T was isolated from the roots of Psammosilene tunicoides collected from Gejiu, Yunnan province, China. The cells of strain YIM DR1026T were Gram-negative and short-rod shaped. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain YIM DR1026T was a member of the genus Aureimonas and closely related to Aureimonas rubiginis (96.7%). DNA–DNA relatedness values between strain YIM 1026T and Aureimonas rubiginis BCRC 80440T was 38.2 ± 1.5%. The ANI value between YIM DR1026T and other Aureimonas members were below the cut-off level (95–96%) recommended as the average nucleotide identity (ANI) criterion for interspecies identity. Strain YIM DR1026T grew at 4–30 °C (optimum 28 °C), pH 4.0–9.0 (optimum pH 6.0–7.0) and tolerated NaCl (w/v) up to 1% (optimum 0%). Q-10 was sole the respiratory ubiquinone present in YIM DR1026T. Polar lipids of strain YIM DR1026T were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine, sulfoquinovosyldiacylglycerol, unidentified aminolipid and unidentified polar lipid. The genomic G + C content was 64.6 mol%. The major fatty acids were C18:1ω7c, C16:0 and summed feature 3 (C16:1ω7c/C16:1ω6c). Based on phenotypic, phylogenetic, chemotaxonomic and genome comparison, strain YIM DR1026T represents a novel species of the genus Aureimonas, for which the name Aureimonas psammosilene sp. nov. is proposed. The type strain is YIM DR1026T (= KCTC 42691T = NBRC 112412T). [ABSTRACT FROM AUTHOR]
