Deinococcus cellulosilyticus sp. nov., isolated from air.

A pink-coloured bacterial strain, 5516J-15(T), was isolated from an air sample from Jeju Island, Republic of Korea. The organism was found to have resistance to UV radiation typical of members of the genus Deinococcus, and it was placed within the radiation of the Deinococcus on a phylogenetic tree based on 16S rRNA gene sequences. Strain 5516J-15(T) shared low 16S rRNA gene sequence similarity (84.5-87.8 %) with Deinococcus species, showing highest sequence similarity to Deinococcus deserti VCD115(T) (87.8 %) and Deinococcus indicus Wt/1a(T) (87.8 %). Strain 5516J-15(T) had type A3 beta peptidoglycan with l-ornithine, menaquinone 8 (MK-8) as the major quinone and iso-C(12 : 0), anteiso-C(13 : 0), iso-C(16 : 0) and C(16 : 0) as the major fatty acids. Its polar lipid profile contained three unknown aminophospholipids, two unknown polar lipids, one unknown phospholipid and one unknown glycolipid. The DNA G+C content of strain 5516J-15(T) was 61.3 mol%. Based on the phylogenetic and phenotypic data presented, it is proposed that the unknown strain should be classified within a novel species in the genus Deinococcus with the name Deinococcus cellulosilyticus sp. nov. The type strain is 5516J-15(T) (=KACC 11606(T) =DSM 18568(T)).
