摘要
为了研究乳酸菌和纳豆芽孢杆菌对霉菌毒素的吸附作用,采用L_9(3~4)正交试验设计,研究不同菌浓度、环境温度及吸附时间对吸附作用的影响。结果表明,乳酸菌和纳豆芽孢杆菌对黄曲霉毒素B_1和伏马毒素B_1的吸附作用主要受菌浓度的影响(P<0.05),温度和时间对吸附强度无显著影响。浓度为1×10~9CFU/m L时,乳酸菌对黄曲霉毒素B_1的吸附强度(18.02%)显著高于纳豆芽孢杆菌(13.88%)(P<0.05),对伏马毒素B_1的吸附强度(13.45%)显著低于纳豆芽孢杆菌(17.62%)(P<0.05)。建议提高菌群数量及种类以去除饲料中霉菌毒素的危害。
To investigate the adsorption of Lactobacillus and Bacillus natto on mycotoxin,the L_9(3~4) orthogonal experimental design method was used to study the effects of different bacterial concentrations,environmental temperatures and times on adsorption in this experiment. The results showed that the adsorption of Lactobacillus and Bacillus natto on aflatoxin B_1 and fumonision B_1 were mainly affected by their concentrations( P < 0. 05),but not significantly affected by adsorption time and environmental temperature. The adsorption intensity of Lactobacillus on aflatoxin B_1( 18. 02%) was higher than that of Bacillus natto( 13. 88%) at the concentration of 1 × 109 CFU/m L,whereas that of Lactobacillus on fumonision B_1( 13. 45%) was lower than that of Bacillus natto( 17. 62%)( P < 0. 05). So increasing the amounts and species of microorganisms should be proposed to reduce the risk of mycotoxin in feed.
