An Antibiotic from Actinomycetes Becoming Effective for Cephalosporin Resistant Pathogenic Pesudomonas sp.
방선균이 생산하는 Cephalosporin 내성 병원성 Pseudomonas에 유효한 항생물질
Abstract
We isolated activnmycetes LAM-98-80 as strain producing an effective antibiotic for cephalosporin re-sistant pathogenic PSeudomonas sp. and identified as Streptomyces sp. LAM-98-80 from cultural and phyisological characteristics. We investigated the optimal culture conditions for producation of an anti-biotic becoming effective for cephalsporin-resistant pathogenic Pseudomonas sp. It was found that 1.5% soluble starch and 1.0% yeast extract were good as carbon and nitrogen source respectively. The pro-duction of antibiotic was also activated by 0.04% Mn2+ as 80% degree. The optimum initial pH on pro-ductio of antibiotic was pH 7.0. The culture condition for the maximal productivity of the antibiotic was at 3
