摘要
为了扩大竹醋液的应用范围,解决竹炭产业副产物过剩难题,采用抑菌圈法测定竹醋液对5种细菌(大肠杆菌Escherichia coli、猪沙门氏菌Salmonella choleraesuis、志贺氏菌Shigella castellani、枯草芽孢杆菌Bacillus subtilis、霍乱弧菌Vibrio cholerae)的杀菌活性,采用TCID50法测定竹醋液对4种病毒(肝炎病毒Hepatitis viruses、胃肠炎病毒Gastroenteritis virus、脊髓灰质炎病毒Poliomyelitis virus、柯萨奇病毒Coxsachie virus)的杀灭活性,采用微量点滴法和直接涂片镜检法测定竹醋液对4种卫生害虫(家蝇Musca domestica、结肠小袋纤毛虫Balantidium coli malmsten、短膜壳绦虫Hymenolepiasis nana、蛲虫Enterobius vermicularis)的毒杀效果。结果表明,有机酸浓度1.44%~7.2%竹醋液对5种细菌均有较强的抑制作用,对细菌的杀灭率均可达到50%以上;有机酸浓度2.4%~7.2%竹醋液具有较高的抗病毒活性,抗病毒效果均可达到50%以上;有机酸浓度1.44%~7.2%竹醋液对4种卫生害虫有明显的触杀或虫体病变活性,对卫生害虫的杀灭率均达到50%以上。以上研究结果表明,竹醋液在一定剂量范围内可作为天然生活垃圾处理剂。
Experiments were conducted on effect of different concentration(1.44%-7.2%)of bamboo pyroligneous liquor on Escherichia coli,Salmonella choleraesuis,Shigella castellani,Bacillus subtilis and Vibrio cholerae by inhibition zone.50%tissue culture infective dose was used to determine effect of different concentration(2.4%-7.2%)of bamboo pyroligneous liquor on Hepatitis viruses,Gastroenteritis viral,Poliomyelitis virus and Coxsachie virus.The effect of 1.44%-7.2%of bamboo pyroligneous liquor was carried out on Balantidium coli malmsten,Hymenolepiasis nana and Enterobius vermicularis.The result demonstrated that different concentrations of bamboo pyroligneous liquor had more than 50%effect on tested bacteria,virus and parasite.
