Two new marine actinobacteria, designated as J2-1T and J2-2T, were isolated from a coral, Favites pentagona, collected from Rayong Province, Thailand. The taxonomic positions of the two strains were identified based on polyphasic taxonomy. Based on morphological characteristics and chemotaxonomy, strains J2-1T and J2-2T were identified as members of the genus Streptomyces and Kineosporia , respectively. Strains J2-1T and J2-2T showed the highest 16S rRNA gene sequence similarity to Streptomyces broussonetiae T44T (98.62 %) and Kineosporia babensis VN05A0415T (98.08 %), respectively. Strain J2-1T had chemotaxonomic properties resembling members of the genus Streptomyces . ll-Diaminopimelic acid, glucose and ribose were detected in the whole-cell hydrolysate. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositolmannoside, unidentified aminolipid and five unidentified phospholipids were detected as the polar lipids. The major cellular fatty acids were C16 : 0 iso, C15 : 0 anteiso, C15 : 0 iso, C16 : 0, C17 : 0 anteiso, C14 : 0 iso and C17 : 0 iso. Strain J2-2T a showed similar cell composition to members of the genus Kineosporia . Both isomers of ll- and meso-diaminopimelic acid were detected in the peptidoglycan. Arabinose, galactose, madurose and xylose were observed in the whole-cell hydrolysate. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, phosphatidylcholine, an unidentified phospholipid and an unidentified glycolipid. The major cellular fatty acids were C16 : 0, C18 : 1 ω9c, C18 : 0 10-methyl, tuberculostearic acid, C18 : 0 and C17 : 0. Both strains could be distinguished from their closely related type strains according to their phenotypic characteristics. Comparative genome analysis indicated the delineation of two novel species based on digital DNA–DNA hybridization and average nucleotide identity values, which were below 70 and 95 %, respectively. The names proposed are Streptomyces corallincola sp. nov. (J2-1T=TBRC 13503T=NBRC 115066T) and Kineosporia corallincola sp. nov. (J2-2T=TBRC 13504T=NBRC 114885T).

Heavy metal resistant bacteria play an important role in the metal biogeochemical cycle in soil, but the benefits of microbial oxidation for plants and soil have not been well-documented. The purpose of this study was to explore the contribution of two Bacillus spp. to alleviate the antimony (Sb) toxicity in plants, and, then, to propose a bioremediation method for Sb contaminated soil, which is characterized by environmental protection, high efficiency, and low cost. This study explored the effects of Bacillus cereus HM5 and Bacillus thuringiensis HM7 inoculation on Broussonetia papyrifera and soil were evaluated under controlled Sb stressed conditions (0 and 100 mmol/L, antimony slag) through a pot experiment. The results show that the total root length, root volume, tips, forks, crossings, and root activities of B. papyrifera with inoculation are higher than those of the control group, and the strains promote the plant absorption of Sb from the soil environment. Especially in the antimony slag treatment group, B. cereus HM5 had the most significant effect on root promotion and promoting the absorption of Sb by B. papyrifera. Compared with the control group, the total root length, root volume, tips, forks, crossings, and root activities increased by 64.54, 70.06, 70.04, 78.15, 97.73, and 12.95%, respectively. The absorption of Sb by root, stem, and leaf increased by 265.12, 250.00, and 211.54%, compared with the control group, respectively. Besides, both B. cereus HM5 and B. thuringiensis HM7 reduce the content of malondialdehyde, proline, and soluble sugars in plant leaves, keeping the antioxidant enzyme activity of B. papyrifera at a low level, and alleviating lipid peroxidation. Principal component analysis (PCA) shows that both B. cereus HM5 and B. thuringiensis HM7 are beneficial to the maintenance of plant root functions and the improvement of the soil environment, thereby alleviating the toxicity of Sb. Therefore, B. cereus HM5 and B. thuringiensis HM7 in phytoremediation with B. papyrifera is a promising inoculant used for bacteria-assisted phytoremediation on Sb contaminated sites.

“…As major plant endophytes, they are notably active in the rhizosphere [9]. Numerous Streptomyces species were discovered in rhizospheres of wild plants (nettle) [10], of agricultural crops (maize, wheat) [11,12] or of trees (populous, paper mulberry) [13,14]. In such environments, they play a major role in phosphate solubilization, nitrogen fixation and other nutrition processes [15].…”

Strain RHZ10T was isolated from an oak rhizosphere sampled in Reims, France, and characterized to assess its taxonomy. Based on 16S rRNA gene sequence similarity, strain RHZ10T was affiliated to the genus Streptomyces and the closest species were Streptomyces anulatus NRRL B-2000T and Streptomyces pratensis ch24T. Average nucleotide identity and digital DNA–DNA hybridization values were 77.3–92.4 % and 23.0–50.9 %, respectively, when compared to the type strains of fully sequenced related species having a 16S rRNA gene sequence similarity over 98 %. These data suggested that strain RHZ10T represented a novel species within the genus Streptomyces . The genome of RHZ10T was 8.0 Mbp long, had 7 894 predicted coding genes, and a G+C content of 71.7 mol%. Cultures of RHZ10T on ISP 2 medium mostly led to the production a green pigmentation of the core of its colonies in the vegetative mycelium, surrounded by white pigmentation of the aerial mycelium. The main fatty acids of RHZ10T were anteiso-C15 : 0, iso-C16 : 0, anteiso-C17 : 0 and C16 : 0. Polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, unidentified lipids, unidentified phospholipids, unidentified aminolipids and unidentified glycolipids. Its main quinones were MK-9(H6) (69.3 %), MK-9(H4) (17.3 %) and MK-9(H8) (17.0%). Phylogenetic, physiological and chemotaxonomic studies clearly supported that strain RHZ10T represents a novel species within the genus Streptomyces , for which the name Streptomyces durocortorensis sp. nov. is proposed and the type strain is RHZ10T (=DSM 112634T=LMG 32187T=CIP 111907T).
