Promoter sequences recognized by Escherichia coli RNA polymerase were isolated from Brevibacterium sp. R312, a coryneform strain producing nitrile hydratase and amidase. Ten Escherichia coli clones containing promoter sequences were selected for their ability to grow with chloramphenicol concentrations of up to 1500 micrograms/ml. The strength of these promoter sequences was determined. We carried out a preliminary study of the strongest promoter having a chloramphenicol acetyl-transferase/beta-lactamase activities ratio of 18.4.
