- 論文の詳細を見る
A search was undertaken for microorganisms that produce an enzyme capable of deacylating 7β-(4-carboxybutanamido)cephalosporanic acid (glutaryl 7-ACA, GL-7-ACA) to 7-aminocephalosporanic acid. Pseudomonas putida ATCC 950 was selected from our stock cultures, and Pseudomonas SY-77-1 was isolated from soil. Adding glutaric acid to the growth media enhanced the production of GL-7-ACA acylase by Pseudomonas SY-77-1. A β-lactamase-deficient mutant, Pseudomonas NS-2, was derived from Pseudomonas SY-77-1 treated with a mutagen. The cell suspension of Pseudomonas NS-2 specifically hydrolyzed cephalosporin compounds having aliphatic dicarboxylic acid in the acyl side chain.
