Project description:We reported transcriptome profiles of rifamycin SV-produced strain Amycolatopsis mediterranei U32 in the Bennet medium with or without 80 mM nitrate in different cultivation stage. By comparative analysis of genome-wide gene expression in these conditions, we found that the mechanism of high production of rifamycin SV induced by nitrate could be elucidated.

Examination of 2 time-course transcription in 2 different nitrogen source conditions
Project description:Amycolatopsis mediterranei DSM 46096 produces antibiotics of the rifamycin family, 27-demethoxy-27-hydroxyrifamycin B, 25-desacetyl-27-demethoxy-27-hydroxyrifamycin, and 27-demethoxy-27-hydroxyrifamycin SV, which are effective against Gram-negative bacteria. Here, we present the draft genome of A. mediterranei 46096 (approx. 10.2 Mbp) having 104 contigs with a GC content of 71.3% and 9,382 coding sequences.
