摘要
通过对链霉菌702所产生物活性物质的稳定性测定研究,试验结果表明,链霉菌702发酵液分别在100℃和121℃处理10h和1h,紫外线照射3min和在pH3～pH12缓冲液中处理60min后,分别对枯草芽孢杆菌、啤酒酵母和青霉的抑菌活性不减。说明该抑菌物质对热和紫外线稳定,在pH3-pH12条件稳定。本研究为进一步对该抑菌活性物质分离提取工艺和其在实践上的应用,提供了有益的试验数据。
The physical and chemical stability of the bioactive compound obtained from Streptomyces 702's fermented broth were tested. The bioactive compound from fermented broth has antibacterial action on B.subtilis, Saccharomyces cerevisiae and Penicillium citrinum. The bioactive compound is ultraviolet-stable, acid- base-stable under pH3.0-pH12.0 and heat-stable treated by 100℃ for 10h, and even by 121℃ for 60min.The statistics will be useful for the further study on the bioactive compound.
