A yellow-pigmented bacterial strain, designated Y2T, was isolated from farmland soil in Bengbu, Anhui province, China. Cells of strain Y2T were Gram-stain-negative, strictly aerobic, non-motile and rod-shaped. Strain Y2T grew optimally at pH 7.0, 30 °C and in the presence of 2 % (w/v) NaCl. The DNA G+C content was 68.9 mol%. The major fatty acids (>5 %) were iso-C15 : 0, iso-C17 : 0, summed feature 9 (C16 : 0 10-methyl and/or iso-C17 : 1ω9c), iso-C11 : 0 3-OH and iso-C11 : 0. The major respiratory quinone was ubiquinone-8 (Q-8), and the major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. Phylogenetic analysis of the 16S rRNA gene sequences showed that strain Y2T was most closely related to Luteimonas mephitis B1953/27.1T (99.1 % 16S rRNA gene sequence similarity), followed by Luteimonas lutimaris G3T (98.6 %), Luteimonas abyssi XH031T (96.2 %) and Luteimonas aquatica RIB1-20T (96.0 %). Strain Y2T exhibited low DNA–DNA relatedness with Luteimonas mephitis B1953/27.1T (43.6 ± 0.5 %) and Luteimonas lutimaris G3T (43.9 ± 2.1 %). On the basis of phenotypic, genotypic and phylogenetic evidence, strain Y2T represents a novel species of the genus Luteimonas, for which the name Luteimonas soli sp. nov. is proposed. The type strain is Y2T ( = ACCC 19799T = KCTC 42441T).

Abstract Strain SZY PN-1T, representing a novel Gram-negative, aerobic, non-motile, rod-shaped and yellow-pigmented bacterium, was isolated from a skin sample of a healthy Chinese people. Growth of SZY PN-1T optimally occurred at pH 7.0, at 30 ºC and tolerate up to 1.0 % (w/v) NaCl. According to the absorption spectrum, carotenoid was present in the cells. Comparative analysis of the 16S rRNA gene revealed that strain SZY PN-1T shared high similarities with Sandaracinobacter sibiricus RB16-17T (97.1 %) and Sandaracinobacter neustonicus JCM 30734T (96.6 %), respectively. Phylogenetic analysis of 16S rRNA gene sequences together with protein-concatamer tree showed that SZY PN-1T formed a separate branch within the genus Sandaracinobacter. The DNA G+C content of the strain SZY PN-1T was 65.0 % (genome). The polar lipid profile included phosphatidylethanolamine, phosphatidylglycerol, two sphingoglycolipids, diphosphatidylglycerol, five unidentified glycolipids and seven unidentified lipids. The predominant fatty acids (> 10.0 %) were identified as C18:1 ω7c and/or C18:1 ω6c, C17:1 ω6c, C16:1 ω7c and/or C16:1 ω6c. The major respiratory quinone was ubiquinone Q-10. Based on the phenotypic and genotypic features, we proposed Sandaracinobacter hominis sp. nov. with type strain SZY PN-1T (= KCTC 82150T = NBRC 114675T).

A novel aerobic, chemoheterotrophic bacterium, strain YO-36T, isolated from the rhizoplane of an aquatic plant (a reed, Phragmites australis) inhabiting a freshwater lake in Japan, was morphologically, physiologically and phylogenetically characterized. Strain YO-36T was Gram-negative and ovoid to rod-shaped, and formed pinkish hard colonies on agar plates. Strain YO-36T grew at 20–40 °C with optimum growth at 30–35 °C, whilst no growth was observed at 15 °C or 45 °C. The pH range for growth was 5.5–8.5 with an optimum at pH 6.5. Strain YO-36T utilized a limited range of substrates, such as sucrose, gentiobiose, pectin, gellan gum and xanthan gum. The strain contained C16 : 0, C16 : 1, C14 : 0 and C15 : 0 as the major cellular fatty acids and menaquinone-12 as the respiratory quinone. The G+C content of the genomic DNA was 62.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain YO-36T belonged to the candidate phylum OP10 comprised solely of environmental 16S rRNA gene clone sequences except for two strains, P488 and T49 isolated from geothermal soil in New Zealand; strain YO-36T showed less than 80 % sequence similarity to strains P488 and T47. Based on the phylogetic and phenotypic findings, a new genus and species, Armatimonas rosea gen. nov., sp. nov., is proposed for the isolate (type strain YO-36T  = NBRC 105658T  = DSM 23562T). In addition, a new bacterial phylum named Armatimonadetes phyl. nov. is proposed for the candidate phylum OP10 represented by A. rosea gen. nov., sp. nov. and Armatimonadaceae fam. nov., Armatimonadales ord. nov., and Armatimonadia classis nov.
