BACTERICIDAL AND ANTIVIRAL EFFECTS OF BAMBOO VINEGAR WITH DIFFERENT CONCENTRATIONS ON DOMESTIC WASTE

摘要

Bamboo vinegar, a brown-red transparent liquid with volatility and unique smoky flavor collected from condensed steam during thermolysis process of bamboo charcoal production. In order to enlarge the application range of bamboo vinegar and solve the surplus problem of bamboo vinegar in bamboo charcoal industry, this work is a test analysis on the bactericidal and antiviral effects of bamboo vinegar with various concentrations on domestic waste. Firstly, the fungicidal activities in vitro of bamboo vinegar in terms of inhibition rate in hypha growth were tested and the result showed that bamboo vinegar with the concentration 7.2%-1.4% has strong inhibitory effect against the tested pathogens. Secondly, the antiviral activities of bamboo vinegar by TCID_(50), which showed that bamboo vinegar of 7.2%-2.4% has exhibited high antiviral activities. Thirdly, the stomach toxicities and worms lesion activities of bamboo vinegar by microtitration and direct smear, which showed that bamboo vinegar of 7.2%-1.4% has significant stomach or worms lesion activities. Fourthly, animal safety tests including the mouse acute oral toxicity test, mouse bone marrow polychromatic erythrocyte micronucleus test and intact dermal irritation test in rabbits were carried out. The results showed that bamboo vinegar, within a certain dose range, is a safe, natural waste treatment agent with no toxicity, no stimulation and no teratogenicity.
