蜗牛(Bradybaena kiangsinensis Martens)是我国的特有种群,它的腺体中含有多种生物活性物质。由于蜗牛在农业生产中具有一定的危害性,而忽视了其在生防中的作用。为探索蜗牛用于生防的可能性,作者对蜗牛提取液的抑菌和溶菌效果进行了研究。 1 材料与方法蜗牛液采用活体提取法,以无菌水作提取介质,用量为蜗牛量的30％,常温下浸提1h,然后过滤备用,以无菌水作提取液对照。抑菌试验采用含毒介质法,即取9ml PDA培
Snail (Bradybaena kiangsinensis Martens) is endemic to our country, its gland contains a variety of bioactive substances. Because snails have a certain degree of harmfulness in agricultural production, they ignore the role of snail in biological prevention. To explore the possibility of snail for biological control, the authors studied the bacteriostatic and bacteriolytic effects of snail extract. 1 Materials and methods Snail liquid using in vivo extraction method to extract the medium with sterile water, the amount of 30% of the amount of snails, leaching 1h at room temperature, and then filtered back to sterilized water extract control. Antibacterial test using toxic medium law, that take 9ml PDA culture
