A novel strain, named S4T, was obtained from industrial wastewater in Xiaoshan, Zhejiang Province, China. Cells were Gram-negative, neutrophilic and non-spore-forming and moved by means of a polar flagellum. Normal cells were 0.8–0.9×1.3–1.9 µm and the cells elongated to 10–25 µm when cultivated at high temperatures. Strain S4T grew at 15–50 °C (optimum at 48 °C), pH 5.5–8.5 (optimum 7.0–7.5) and 0–2 % (optimum 0.5 %) (w/v) NaCl. Ubiquinone-8 was the predominant respiratory quinone. C16 : 0, summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) and C17 : 0 cyclo were the major cellular fatty acids. The major 3-OH fatty acid was C10 : 0 3-OH. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and an unknown aminoglycolipid. The genomic DNA G+C content was 68.8 mol%. Based on 16S rRNA gene sequences alignment, the most closely related strains were members of the genera Comamonas (94.6–95.6 % similarities), Giesbergeria (94.9–95.6 %), Acidovorax (94.8–95.4 %), Brachymonas (94.1–95.2 %) and Macromonas (95.1 %). Phylogenetic analysis showed the closest relatives of strain S4T were members of the genus Macromonas . Based on phenotypic and phylogenetic characteristics, we suggest that strain S4T represents a novel species of a new genus of the family Comamonadaceae , for which the name Extensimonas vulgaris gen. nov., sp. nov. is proposed. The type strain of Extensimonas vulgaris is S4T ( = CGMCC 1.10977T = JCM 17803T).

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.
