Xylanibacillus composti gen. nov., sp nov., isolated from compost

A novel Gram-stain-positive bacterial strain, designated as K13(T), was isolated from compost and characterized using a polyphasic approach to determine its taxonomic position. On the basis of 16S rRNA gene sequence analysis, the strain showed highest similarity (93.8 %) to Paenibacillus nanensis MX2-3(T). Cells of strain K13(T) were aerobic, motile rods. The major fatty acids were anteiso C-15:0 (34.4 %), iso C-16:0 (17.3 %) and C-16:0 (10.0 %). The major menaquinone was MK-7, the polar lipid profile included diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylserine and an aminophospholipid. The DNA G+C content was 52.3 %. Based on phenotypic, including chemotaxonomic characteristics and analysis of the 16S rRNA gene sequences, it was concluded that strain K13(T) represents a novel genus, for which the name Xylanibacillus gen. nov., sp. nov. is proposed. The type species of the genus is Xylanibacillus composti, the type strain of which is strain K13(T) (=DSM 29793(T)=NCAIM B.02605(T)).
