Abstract

A pink-pigmented, facultatively methylotrophic bacterium, strain CBMB20, isolated from stem tissues of rice, was analysed by a polyphasic approach. Strain CBMB20 utilized 1-aminocyclopropane 1-carboxylate (ACC) as a nitrogen source and produced ACC deaminase. It was related phylogenetically to members of the genus . 16S rRNA gene sequence analysis indicated that strain CBMB20 was most closely related to , and ; however, DNA–DNA hybridization values were less than 70 % with the type strains of these species. The DNA G+C content of strain CBMB20 was 70.6 mol%. The study presents a detailed phenotypic characterization of strain CBMB20 that allows its differentiation from other species. In addition, strain CBMB20 is the only known member of the genus to be described from the phyllosphere of rice. Based on the data presented, strain CBMB20 represents a novel species in the genus , for which the name sp. nov. is proposed, with strain CBMB20 (=DSM 18207=LMG 23582=KACC 11585) as the type strain.
