Process to increase the production of clavam antibiotics

摘要

A process for increasing the amount of clavam produced by an organism having both a clavam pathway or a portion thereof and a cephalosporin pathway or a portion thereof by interfering with the conversion of L-lysine to L-alpha-aminoadipic acid in the cephalosporin pathway. Plasmids containing a defective LAT (lysine amino transferase) gene and organisms containing such plasmids are also provided.
