A bacterial strain, designated J6(T), was isolated from activated sludge, collected from a chemical wastewater treatment system in Zhejiang Province of China. The cells stained Gram-negative, were aerobic, pale-yellow, and non-motile short rods. Phylogenetic analysis of the 16S rRNA gene sequence indicated that the closest relative of this organism was Paracoccus aminophilus KACC 12262(T) = JCM 7686(T) (97.4 % sequence similarity). Strain J6(T) grew at 10-37 °C (optimum 30 °C), at pH 6.0-8.0 (optimum pH 7.0) and with 0-5 % NaCl (optimum 3 %, w/v). The predominant cellular fatty acid found was summed feature 8(C18:1 ω7c and/or C18:1 ω6c; 82.8 %). The major respiratory quinone-detected was Q-10 and the DNA G+C content was 61.9 mol %. The polar lipid profile consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine and several unknown polar lipids. Strain J6(T) showed low DNA-DNA relatedness values with P. aminophilus KACC 12262(T) (28 ± 3 %). The phylogenetic analysis, DNA-DNA hybridization, whole-cell fatty acid composition as well as biochemical characteristics allowed clear differentiation of the isolate from the other type strains of already described Paracoccus species. It is evident from the genotypic, phenotypic and chemotaxonomic analyses that strain J6(T) should be classified as a novel species of the genus Paracoccus, for which the name P. zhejiangensis sp. nov. is proposed. The type strain is J6(T) (KACC 16703(T) = CCTCC AB 2012031(T)).
The Cover Feature shows the hydrogen and oxygen evolution from water by using ultrathin two‐dimensional metal–organic nanosheets (2D MONs) as heterogeneous photocatalysts and electrocatalysts. Moreover, the recent development of 2D MON‐based photo‐ or electrocatalysts enables oxygen reduction reaction (ORR), carbon dioxide reduction reaction (CO2RR), as well as organic transformations.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
