Abstract:
:Three short spore chain-forming actinomycete strains were isolated from soil samples collected from subtropical islands in Japan. The cell-wall peptidoglycan of these strains contained meso-diaminopimelic acid (meso-A(2)pm), glutamic acid and alanine. The major isoprenoid quinone was MK-9(H(4)), iso-C(16 : 0) and 2-OH iso-C(16 : 0) were the major cellular fatty acids and phosphatidylethanolamine was a component of the polar lipids. The G+C content of the genomic DNA was 67-69 mol%. Phylogenetic analyses based on the 16S rRNA gene sequences showed that the novel strains consistently formed a monophyletic cluster with Amycolatopsis taiwanensis. On the basis this polyphasic taxonomical study, it is proposed that the two new isolates represent two novel species: Amycolatopsis helveola (type strain TT00-43(T)=NBRC 103394(T)=KCTC 19329(T)) and Amycolatopsis pigmentata (type strain TT99-32(T)=NBRC 103392(T)=KCTC 19330(T)).
