摘要
试验以多黏类芽孢杆菌为试验对象,以豆粕、麸皮、玉米粉、碳酸钙等为发酵培养基的主要成分,以家禽养殖生产中常见的3种有害菌(大肠杆菌、沙门菌和金黄色葡萄球菌)为目标菌,通过测定不同发酵时间发酵液的抑菌圈大小,研究发酵液的抑菌效果。结果表明:多黏类芽孢杆菌发酵液对3种目标菌的抑制效果为金黄色葡萄球菌>大肠杆菌>沙门菌,且经加热处理后的发酵液抑菌效果更佳。
In this study,Paenibacillus polymyxa was chosen to ferment the medium mainly containing soybean meal,bran,corn flour and calcium carbonate.To investigate the antibacterial activity of fermentation broth against Escherichia coli,Salmonella and Staphylococcus aureus,which were typical harmful bacteria in animal production,Paenibacillus polymyxa fermentation broth was collected at different times to evaluate the antibacterial activity by measuring the diameter of inhibition zones against the target bacteria.The results showed that the antibacterial activity of Paenibacillus polymyxa fermentation broth against three bacteria were Staphylococcus aureus>Escherichia coli>Salmonella,and the better antibacterial effect could be achieved after heat treatment.
