痂囊腔菌素A光敏抑菌性能的研究

Study on Photosensitive Bacteriostasis Activity of Elsinochrome A.

目的:研究和分析痂囊腔菌素A的光敏抑菌活性。方法:以金黄色葡萄球菌、枯草杆菌、大肠杆菌、普通变形杆菌为实验菌株,通过Kirby-Bauer纸片扩散法实验测定痂囊腔菌素A抑菌圈直径。结果:痂囊腔菌素A对革兰氏阳性细菌生长具有明显的光敏抑制作用,而对革兰氏阴性细菌,无论在光下或在黑暗中皆无抑制作用。结论:痂囊腔菌素A具有光敏生物活性,对革兰氏阳性细菌具有光敏抑制作用。

Objective:To investigate and analyze the photosensitive bacteriostasis activity of Elsinochrome A.Methods:To determine the inhibition zone diameters of Elsinochrome A to Staphylococcus aureus,Bacilus subtilus,E.coli and Proteus vulgaris in the Kirby-Bauer paper diffusion experiment.Results:Elsinochrome A had remarkabl photosensitive inhibitory effects on Gram-positive bacterial growth in light,and that had not inhibitory effects on Gram-negative bacterial growth in light or dark.Conclusions:Elsinochrome A had photosensitive biological activity,and it had photosensitive inhibitory effects on Gram-positive bacterial growth.
