A novel Gram-stain-positive, endospore-forming bacterium, designated FJAT-22460T, was isolated from a soil sample of a potato field in Xinjiang Autonomous Region, China. Cells were rods that were catalase-positive and motile by peritrichous flagella. The strain was found to grow at temperatures ranging from 10 to 40 °C (optimum 30 °C) and at pH 5.0-12.0 (optimum pH 7) with 0-5 % (w/v) NaCl (optimum 0 % NaCl). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain FJAT-22460T belonged to the genus Paenibacillus and exhibited 16S rRNA gene sequence similarities of 97.3, 97.2, 97.2 and 97.0 % with Paenibacillus glucanolyticus DSM 5162T, Paenibacillus lautus DSM 3035T, Paenibacillus lactis MB 1871T and Paenibacillus chibensis JCM 9905T, respectively. DNA-DNA relatedness of strain FJAT-22460T with Paenibacillus glucanolyticusDSM 5162T and Paenibacillus lautus DSM 3035T was 62.6 % and 33.3 %, respectively, lower than the 70 % accepted for species delineation. The menaquinone was identified as MK-7. The major fatty acids detected were anteiso-C15 : 0 (51.4 %), iso-C15 : 0 (5.3 %), C16 : 0 (12.1 %), iso-C16 : 0 (10.7 %) and anteiso-C17 : 0 (6.9 %). The DNA G+C content was determined to be 50.9 mol%. Phenotypic, chemotaxonomic and genotypic properties clearly indicated that isolate FJAT-22460T represents a novel species within the genus Paenibacillus, for which the name Paenibacillus solani sp. nov. is proposed. The type strain is FJAT-22460T (=DSM 100999T=CCTCC AB 2015207T).
A novel Gram-stain-positive, endospore-forming bacterium, designated strain FJAT-18043 T ,was isolated from a soil sample of a potato field in Xinjiang Autonomous Region, China. Cells were rods that were catalase-positive and motile by peritrichous flagella. The strain grew at 20-45 8C (optimum 35 8C), at pH 6.0-10.0 (optimum pH 9) and with 0-10 % (w/v) NaCl (optimum 0 %
ABSTRACT. Octopus in the family Octopodidae (Mollusca: Cephalopoda) has been generally recognized as a "catch-all" genus. The monophyly of octopus species in China's coastal waters has not yet been studied. In this paper, we inferred the phylogeny of 11 octopus species (family Octopodidae) in China's coastal waters using nucleotide sequences of two mitochondrial DNA genes: cytochrome c oxidase subunit I (COI) and 16S rRNA. Sequence analysis of both genes revealed that the 11 species of Octopodidae fell into four distinct groups, which were genetically distant from one another and exhibited identical phylogenetic resolution. The phylogenies indicated strongly that the genus Octopus in China's coastal waters is also not monophyletic, and it is therefore clear that the Octopodidae systematics in this area requires major revision. It is demonstrated that partial sequence information of both the mitochondrial genes 16S rRNA and COI could be used as diagnostic molecular markers in the identification and resolution of the taxonomic ambiguity of Octopodidae species.
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.
