Abstract

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 ‘’ of the family and the order . However, phylogenetic analysis of the 16S rRNA gene sequence of strain DSM 7029 indicated that it was clustered with members of . Significant growth occurred at 25–42 °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 Cω7/Cω6, C and Cω7. The G+C content of genomic DNA was 67.51 mol%. The strain was clearly distinguishable from other neighbouring members and genera and , 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 , for which the name sp. nov. is proposed.
