摘要
Abstract
Active constituents in Kefir were extracted by water,the antibiosis activity on Escherichia coil, Staphylococcus aureus Rosen Bach,Bacillus subtilis,Shigella dysenteries,Sac-charomyces cerevisiae and Aflatoxin was studied by K-B slips. The extracts were treated with different pH,temperature,lights,then bacteriostasis was studied. The results showed that extracted antibacterial substance had shown antibiosis on Gram positive bacteria and Gram negative bacteria and parts of epiphyte. The minimum fungicide concentration of extracts was 6.25-12.5mg/mL. Compared with nisin,the antibiosis activity was limited,and more organisms spectrum. Antibacterial substance had good stability to hot, acidity and light.关键词
