Kribbella sindirgiensis sp. nov. isolated from soil.

A Kribbella strain FSN23T was isolated from soil sample which was collected from Caygoren Dam lakeside located in Sındırgı, Turkey. The isolate was investigated using a polyphasic approach consisting of numeric, chemotaxonomic and molecular analysis. The isolate indicated chemotaxonomic, morphological and phylogenetic properties associated with members of the genus Kribbella. Phylogenetic analysis based on the 16S rRNA sequence of the strain demonstrated that the strain forms a subclade with K. aluminosa HKI 0478T and K. jejuensis HD9T. The organism formed an extensively branched substrate and aerial hyphae which generated spiral chains of spores with smooth surfaces. The cell wall contained LL-diaminopimelic acid, and the whole cell sugars were glucose and ribose along with trace amounts of mannose. The polar lipids were identified as phosphatidylglycerol, diphosphatidylglycerol, four unidentified lipids and five unidentified polar lipids. The predominant menaquinone was MK-9(H4). The major cellular fatty acids were anteiso-C15:0 and iso-C16:0. Polyphasic taxonomy properties confirm that strain FSN23T represents a novel Kribbella taxon distinguished from closely related type strains. Hence, strain FSN23T (=KCTC 29220T = DSM 27082T) is proposed as the type strain of a novel species with the name Kribbella sindirgiensis sp. nov.
