摘要
研究蛹虫草(Cordyceps militaris)的发酵液和菌丝提取物的抑菌效果,为蛹虫草抑菌活性物质的开发利用提供基础资料。采用滤纸柱、海绵柱和花泥柱3种方法检测其抑菌效果,结果表明蛹虫草发酵液及菌丝提取物对大肠杆菌(Escherichia coli)和金黄色葡萄球菌(Staphylococcus aureus)均有一定抑制作用,其中菌丝提取物抑菌作用较强;对大肠杆菌的抑制强于对金黄色葡萄球菌的抑制。抑菌效果检测方法以滤纸柱法检测效果较好,花泥柱法次之,海绵柱法较差。
Fermentation broth and mycelia extraction of Cordyceps militaris in different fermentative days were explored for their antibacterial activities. For the three methods to test the antibacterial effect, the results showed that filter paper method was the best, followed by flower mud column, the worst was sponge column. The inhibition effect of mycelia extraction on both bacteria was stronger than that of fermentation broth; and the inhibition effect of both materials on Escherichia coli was stronger than that on Staphylococcus attreus.
