Strepolyketide D, a new SEK15-derived polyketide compound from salt-lake-derived sp. DBC5.

A new SEK15-derived polyketide compound, strepolyketide D (), was isolated from salt-lake-derived sp. DBC5, together with two known analogues (). Their structures were elucidated based on spectroscopic analysis of IR, MS, 1 D and 2 D NMR.

Paenibacillus wulumuqiensis sp. nov. and Paenibacillus dauci sp. nov., two novel species of the genus Paenibacillus.

Two Gram-staining-positive, aerobic, motile, endospore-forming, rod-shaped bacteria, designated strains Y24(T) and H9(T) were isolated from cold spring and carrot (Daucus L.) samples, respectively, in Xinjiang Uyghur Autonomous Region, north-western China. The taxonomic positions of the two new isolates were determined by using a polyphasic approach.
