摘要: Phenazine 1-carboxylic acid (PCA) is an antifungal antibiotic isolated from a culture filtrate of Bacillus sp. B-6 producing aryl CoA synthetase inhibitor. This reported as inhibitor acyl Pseudomonas sp.. was resistant to PCA up 350 ㎍/㎖. We investigated the mechanism resistance PCA. The rate growth in medium containing 100 ㎍/㎖ rapid PCA-free medium. At concentration 300 ㎍/㎖, more than half that control. In this work, we purified and found much less sensitive other source. These findings suggested insensitivity plays important role bacterium.
