Bacterial amylolytic activity enhances beta-glucuronidase expression of amylase-negative Escherichia coli strain in starch-medium.

abstract：:Many strains of Amycolatopsis, such as Amycolatopsis orientalis, A. balhimycina, and A. mediterranei, are important antibiotic producers. Three indigenous plasmids, pMEA100, pMEA300, and pA387, found in this genus have been sequenced. However, only some vectors based on pA387 have been widely applied in Amycolatopsis ...
