A bacterial strain, designated PECAE04(T), was isolated from root nodules of Cicer arietinum in Spain. Phylogenetic analysis based on 16S rRNA gene sequence placed the isolate into the genus Paenibacillus with its closest relative being Paenibacillus castaneae Ch-32(T) with 98.4 % 16S rRNA gene sequence similarity followed by Paenibacillus glycanilyticus DS-1(T), Paenibacillus prosopidis PW21(T), Paenibacillus xinjiangensis B538(T) and Paenibacillus catalpae D75(T) with similarities ranging from 97.9 to 96.8 %. DNA-DNA hybridization measurements showed values lower than 20 % between the strain PECAE04(T) and any of these species. The isolate was a Gram-stain-positive, motile, sporulating rod. Catalase and oxidase activities were positive. Aesculin was hydrolysed but casein and gelatin were not. Acetoin production, H2S production, nitrate reduction and urease and caseinase production were negative. Growth was supported by many carbohydrates and organic acids as carbon sources. MK-7 was the predominant menaquinone and anteiso-C15 : 0, iso-C16 : 0 and C16 : 0 were the major fatty acids. Major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, a glycolipid, three phospholipids and an unidentified lipid. Meso-diaminopimelic acid was not detected in the peptidoglycan. The DNA G+C content was 52.9 mol%. Phylogenetic, chemotaxonomic and phenotypic analyses showed that strain PECAE04(T) should be considered to be a representative of a novel species of the genus Paenibacillus, for which the name Paenibacillus endophyticus sp. nov. is proposed. The type strain is PECAE04(T) ( = LMG 27297(T) = CECT 8234(T)).

D009693 Nucleic Acid Hybridization Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.
