Abstract

Two xylan-degrading bacterial strains were isolated from a decayed tree in Spain. The isolates were Gram-positive, non-motile, aerobic and formed substrate mycelium which fragmented into irregular rods. 16S rRNA gene sequence analysis indicated that the isolates form a separate branch within the genus phylogenetic cluster, with DSM 20152 being their closest relative (97·7 and 97·6 % sequence similarity). Catalase, nitrate reduction and urease tests differentiated these strains from . Cell-wall peptidoglycan composition, major menaquinone, predominant fatty acids and phospholipid pattern were typical of the genus . The DNA G+C content determined for the type strain XIL01 was 72 mol%. Based on the data presented, a novel species sp. nov. is proposed. The type strain is XIL01 (=LMG 21954=DSM 15747).
