A novel, halophilic, motile, rod-shaped, Gram-staining-negative and non-endospore forming bacterium, designated Cs25T, was isolated from the rhizosphere of the halophyte Arthrocnemum macrostachyum growing in a tidal flat. Strain Cs25T was observed to be catalase-negative and oxidase-positive, and to hydrolyse hypoxanthine. Growth occurred from 15 to 40C, at pH 7.0-10.0 and with 1-11% (w/v) NaCl. Q-10 was identified as the dominant ubiquinone, and the major cellular fatty acids were C18:17c, 11-methyl C18:17c, C20:17c and C18:0. The polar lipids comprised phosphatidylmonomethylethanolamine, phosphatidylcholine, sulphoquinovosyldiacylglyceride, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The 16S rRNA gene showed 99.19, 98.6 and 98.59% sequence identity with Labrenzia alba DSM 18320T, L. aggregata DSM 13394T and L. marina DSM 17023T, respectively. Based on the phenotypic and molecular features and DNA-DNA hybridization data, it is concluded that strain Cs25T represents a novel species for which the name Labrenzia salinasp. nov. is proposed. The type strain is Cs25T (=DSM 29163T=CECT 8816T).

A novel actinobacterial strain, designated DS3010T, was isolated from a Black Sea marine sediment and characterized using a polyphasic approach. The strain was shown to have chemotaxonomic, morphological and phylogenetic properties consistent with classification as representing a member of the genus Micromonospora. Comparative 16S rRNA gene sequence studies showed that the strain was most closely related to the type strains of Micromonospora saelicesensis (99.5%), Micromonospora chokoriensis (99.4%) and Micromonospora violae (99.3%). Similarly, a corresponding analysis based on partial gyrB gene sequences showed that it formed a distinct phyletic branch in a subclade that included the type strains of Micromonosporazamorensis, Micromonospora zeae, Micromonospora jinlongensis, M. saelicesensis and Micromonospora lupini. DS3010T was distinguished from its closest phylogenetic neighbours by low levels of DNA-DNA relatedness and by a combination of chemotaxonomic and phenotypic properties. On the basis of these data, it is proposed that the isolate should be assigned to the genus Micromonospora as Micromonospora profundi sp. nov. with isolate DS3010T (=DSM 45981T=KCTC 29243T) as the type strain.

A strain of filamentous sulfur bacteria was isolated from freshwater spring contaminated with residential and agricultural wastewater in Moscow region, Russia. According to the results of phylogenetic analysis, strain D-402T belonged to the genus Beggiatoa within the family Beggiatoaceae of the class Gammaproteobacteria. Within the genus Beggiatoa, strain D-402T was most closely related to Beggiatoa alba strains. Strain D-402T had a DNA G+C content 42.1 mol %. The similarity to strain B15LD was 33 %. Predominant fatty acids were 18 : 1 (46.1 and 53.3%), 16 : 0 (15.5 and 16.2%), and 16 : 1 (32.9 and 25.4%) for strains D-402T and B15LD, respectively. In contrast to known representatives of Beggiatoa, strain D-402T was capable of chemolithoautotrophic growth with sulfide and thiosulfate as electron donors. Oxidation of sulfide and thiosulfate was accompanied by deposition of sulfur globules within the cells. Strain D-402T was capable of heterotrophic growth. The strain was capable of using different organic compounds, sulfur compounds and hydrogen as electron donors. Based on these observations, strain D-402T is considered as a representative of a species Beggiatoa leptomitoformis sp. nov. of the genus Beggiatoa. The type strain is D-402T (DSM 14946, UNIQEM U 779).
