A Gram-stain-positive, motile, rod-shaped bacterium, designated strain LAM7113T, was isolated from soil sample collected from a birch forest in Xinjiang Uygur Autonomous Region, PR China. Strain LAM7113T grew optimally at pH 8.0, 30 °C and in the presence of 1.0 % NaCl (w/v). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain LAM7113T was closely related to members of the genus Paenibacillus , with the highest similarity to Paenibacillus baekrokdamisoli Back-11T (96.2 %). The genomic DNA G+C content was 43.4 mol%. The values of average nucleotide identity and DNA–DNA hybridization were 66.1 and 27.0 %, respectively, by comparing the draft genome sequences of strain LAM7113T and P. baekrokdamisoli Back-11T. Anteiso-C15 : 0 and iso-C15 : 0 were identified as the major cellular fatty acids. Menaquinone-7 was detected as the predominant respiratory quinone. The major polar lipids were found to be diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, three unidentified aminophospholipids, three unidentified glycolipids, one unidentified phospholipid and two unknown polar lipids. Based on its phenotypic, phylogenetic and chemotaxonomic characteristics, strain LAM7113T is proposed to represent a novel species of the genus Paenibacillus with the name Paenibacillus solisilvae sp. nov. The type strain is LAM7113T (=CGMCC 1.16619T=JCM 32513T).

A novel bacterial strain, designated FGD1T, was isolated from subtropical forest soil of the Nanling National Forest Park located in Guangdong Province, P.R. China. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain FGD1T was most closely related to Novosphingobium lindaniclasticum DSM 25049T (98.8 %), followed by N. barchaimii DSM 25411T (98.7 %), N. guangzhouense DSM 32207T (98.2 %), N. panipatense DSM 22890T (98.1 %) and other species of Novosphingobium (<98 %). The draft genome sequence was 4.58 Mb in length with a G+C content of 65.1 mol%. The calculated average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) values between strain FGD1T and closely related type strains were 77.7‒79.6 % and 21.7–22.9 %, respectively.

Five Gram-stain-negative, catalase- and oxidase-positive, rod-shaped and motile strains (FT50WT, FT80WT, FT92WT, FT94W and FT135WT) were isolated from a subtropical stream in PR China. Comparisons based on 16S rRNA gene sequences showed that strains FT50WT, FT94W and FT135WT take strain Duganella sacchari Sac-22T, and strains FT80WT and FT92WT take strain Duganella ginsengisoli DCY83T as their closest neighbour in the phylogenetic trees, respectively. The G+C contents of strains FT50WT, FT80WT, FT92WT, FT94W and FT135WT were 63.3, 62.4, 62.8, 63.8 and 60.8 %, respectively. The reconstructed phylogenomic tree based on concatenated 92 core genes showed that strains FT50WT, FT80WT, FT94W and FT135WT clustered together with species of the genus Duganella , but strains FT92WT and D. ginsengisoli KCTC 42409T were located in the clades of the genus Massilia . The calculated pairwise average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) values among strains FT50WT, FT80WT, FT92WT, FT94W, FT135WT and related strains were in the ranges of 75.6–87.8% and 20.3–33.8% except that the values between strains FT50WT and FT94W were 98.7 and 89.2%, respectively. The respiratory quinone of these five strains was Q-8. The major fatty acids were C16 : 1  ω7c, C16 : 0, C18 : 1  ω7c and C12 : 0. The polar lipids included phosphatidylethanolamine, phosphatidylglycerol and one unidentified phospholipid. Considering the distinct phylogenetic relationships of D. ginsengisoli with species of the genus Massilia in the phylogenomic tree, it was reasonable to transfer D. ginsengisoli to the genus Massilia as Massilia ginsengisoli comb. nov. Combining the results of phylogenomic analysis, ANI and dDDH data, and a range of physiological and biochemical characteristics together, strains FT50WT and FT94W should belong to the same species and be assigned to genus Duganella with strains FT80WT and FT135WT together, and strain FT92WT should be assigned to the genus Massilia , for which the names Duganella lactea sp. nov. (type strain FT50WT=GDMCC 1.1674T=KACC 21466T), Duganella guangzhouensis sp. nov. (FT80WT=GDMCC 1.1678T=KACC 21470T), Duganella flavida sp. nov. (FT135WT=GDMCC 1.1745T=KACC 21659T) and Massilia rivuli sp. nov. (FT92WT=GDMCC 1.1682T=KACC 21474T) are proposed.

Analysis of the 16S rRNA gene sequence revealed that the isolate had highest sequence similarities to Pontibacter mucosus DSM 100162T (96.5 %) and Pontibacter korlensis X14-1T (96.5 %). The values of average nucleotide identity, average amino acid identity and digital DNA–DNA hybridization between the isolate and its close neighbours were, respectively, less than 80.1, 81.7 and 23.2 %. Chemotaxonomic analysis indicated that the sole respiratory quinone was MK-7 and the predominant cellular fatty acids were summed feature 4 and iso-C15 : 0 (42.2 and 24.6 %, respectively).
