A Gram-stain-negative, non-motile and aerobic bacterium, designated CF17T, was isolated from coastal planktonic seaweeds, East China Sea. The isolate grew at 18–37 °C (optimum 25–28 °C), pH 6.5–9.0 (optimum 7.0–8.0) and with 0–5 % NaCl (optimum 1–2 %, w/v) and 0.5–10 % sea salts (optimum 2–3 %, w/v). Growth of strain CF17T could be stimulated prominently by supplementing the growth medium with the autoclaved supernatant of a culture of strain CF5, which was isolated from the same sample along with strain CF17T. The cell morphology of strain CF17T was a bean-shaped rod consisting of a swollen end and a long prostheca. The phylogenetic analysis of 16S rRNA gene sequences indicated that strain CF17T clustered with Gemmobacter nectariphilus DSM 15620T within the genus Gemmobacter . The DNA G+C content of strain CF17T was 61.4 mol%. The respiratory quinone was ubiquinone Q-10. The major fatty acids included C18 : 1ω7c and C18 : 0. The polar lipids of strain CF17T consisted of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, two uncharacterized phospholipids, one uncharacterized aminolipid, three uncharacterized glycolipids and one uncharacterized lipid. On the basis of phenotypic, phylogenetic and chemotaxonomic data, strain CF17T ( = CGMCC 1.11024T = JCM 18498T) is considered to represent a novel species of the genus Gemmobacter , for which the name Gemmobacter megaterium sp. nov. is proposed.

The taxonomic position of a novel actinomycete, strain RC 1831T, isolated from the sediment of a fish dumping yard at Barkul village near Chilika Lake, Odisha, India, was determined by a polyphasic approach. Based on morphological and chemotaxonomic characteristics the isolate was determined to belong to the genus Streptomyces . The phylogenetic tree based on its nearly complete 16S rRNA gene sequence (1428 nt) with representative strains showed that the strain consistently falls into a distinct phyletic line together with Streptomyces glaucosporus DSM 41689T (98.22 % similarity) and a subclade consisting of Streptomyces atacamensis DSM 42065T (98.40 %), Streptomyces radiopugnans R97 DSM 41901T (98.27 %), Streptomyces fenghuangensis GIMN4.003T (98.33 %), Streptomyces nanhaiensis DSM 41926T (98.13 %), Streptomyces megasporus NBRC 14749T (97.37 %) and Streptomyces macrosporus NBRC 14748T (98.22 %). However, the levels of DNA–DNA relatedness between strain RC 1831T and phylogenetically related strains Streptomyces atacamensis DSM 42065T (28.75±3.25 %) and Streptomyces glaucosporus DSM 41689T (15±2.40 %) were significantly lower than the 70 % threshold value for delineation of genomic species. Furthermore, the isolate could be distinguished phenotypically on the basis of physiological, morphological and biochemical differences from its closest phylogenetic neighbours and other related reference strains. Strain RC 1831T is therefore considered to represent a novel species of the genus Streptomyces , for which the name Streptomyces barkulensis sp. nov. is proposed. The type strain is RC 1831T ( = JCM 18754T = DSM 42082T).
