【摘要】 通过对链霉菌702所产生物活性物质和纳他霉素及Nisin分别对黑曲霉、青霉、绿色木霉、枯草芽孢杆菌、蜡质芽孢杆菌、苏云金芽孢杆菌、产朊假丝酵母、啤酒酵母的抑制作用研究,试验结果得出链霉菌702所产生物活性物质对各种指示菌的半致死浓度和半致死时间,证明链霉菌702所产生物活性物质抑制效果比纳他霉素及Nisin强。试验结果为链霉菌702所产活性物质应用提供了有益的试验数据。更多还原

【Abstract】 The inhibitory action of the bioactive compound produced by Streptomyces 702 ,Nisin and Natamycin on Aspergillus niger,Penicillium chrysogenum,Trichoderma viride,Bacillus subtilis,Bacillus cereus,Bacillus thuringensis,Candida utilis and Saccharomyces cerevisiae was tested. The L_C50 and the L_T50 of the bioactive compound produced by Streptomyces 702,Nisin and Natamycin on the spore of bacteria and fungus were obtained. The result showed that the inhibit effect of the bioactive compound produced by Streptomyces 702 was more powerful than those of Nisin’s and Natamycin’s. The experimental results are useful for the application study of Streptomyces 702.更多还原
