摘要: Strain DSM 7029, isolated from a soil sample in Greece, can produce antitumour glidobactins, and has been found, as a heterologous host, to produce useful nonribosomal peptide synthetase-polyketide synthase hybrid molecules known as epothilones. This strain was originally named 'Polyangium brachysporum' of the family Polyangiaceae and the order Myxococcales. However, phylogenetic analysis of the 16S rRNA gene sequence of strain DSM 7029 indicated that it was clustered with members of Schlegelella. Significant growth occurred at 25-42 degrees C, pH 5.0-10.0 and in the presence of 0-0.2% (w/v) NaCl. The predominant ubiquinone was Q-8. The major fatty acids were C-16 : 1 omega 7c/C-16 : 1 omega 6c, C-16 : 0 and C-18 : 1 omega 7c. The G+C content of genomic DNA was 67.51 mol%. The strain was clearly distinguishable from other neighbouring Schlegelella members and genera Caldimonas and Zhizhongheella, using phylogenetic analysis, fatty acid composition data and a range of physiological and biochemical characteristics and genome analysis. Therefore, strain DSM 7029 represents a novel species of the genus Schlegelella, for which the name Schlegelella brevitalea sp. nov. is proposed.
