Abstract:
Micromonospora sp. strain DB620 was isolated from a Wadden Sea sediment sample collected near Büsum (Germany) and is closely related (99% 16S-rRNA gene sequence similarity) to Micromonospora coxensis strain MTCC8093. It produced a new polyene dicarboxylic acid named diacidene (1) and in addition a derivative of chorismic acid, the known 3-[(1-carboxyvinyl)oxy]benzoic acid. The structure elucidation of 1 was achieved by applying different 1D and 2D NMR techniques as well as mass spectrometry and UV spectroscopy.
