Abstract

Two bacterial strains associated with the white-rot fungus were subjected to taxonomic investigation. The isolates, designated KCTC 12081 and KCTC 12082, were Gram-negative, non-motile, non-spore-forming and ovoid to rod-shaped. The strains contained major amounts of hexadecanoic acid, -heptadecanoic acid and -7--octadecenoic acid in their cell envelopes. Strain KCTC 12081 contained ubiquinone-8 as the major isoprenoid quinone and the G+C content of its genomic DNA was 61·3 mol%. Morphological and chemotaxonomic properties of the strains were consistent with classification in the genus . In a comparison of 16S rDNA sequence, KCTC 12081 shared 100 % similarity with KCTC 12082 and both strains formed a distinct phylogenetic lineage within the genus . The two strains were also differentiated from other species of this genus by fatty acid composition and phenotypic properties. DNA–DNA relatedness data further supported the separation of the new isolates from closely related species. It is therefore proposed that strains KCTC 12081 (=JCM 11778) and KCTC 12082 be recognized as a novel species, for which the name sp. nov. is proposed.
