DESCRIPTION OF SACCHAROMONOSPORA-XINJIANGENSIS SP. NOV. BASED ON CHEMICAL AND MOLECULAR CLASSIFICATION

Comparative studies of morphology, physiology, biochemistry and chemic al composition of cells, and phylogenetic analysis based on 16S rRNA g ene sequences were carried out with strains XJ-54(T) and XJ-58 of the genus Saccharomonospora and type strains of related genera, The result s indicated that the two strains are different from known members of t he genus Saccharomonospora. A new species with the name Saccharomonosp ora xinjiangensis sp. nov, is proposed. The new species is characteriz ed by the presence of longitudinal pairs of spores on both the aerial and the vegetative hyphae and contains phosphatidyl ethanolamine, phos phatidyl choline and unknown glucosamine-containing phospholipids, and the major menaquinones MK-9(H-2), MK-9(H-4) and MK-7(H-4).
