| 摘 要： | 目的研究黑曲霉对黄曲霉生长、产毒的抑制作用及对AFB1的降解作用。方法将黑曲霉分别与黄曲霉、AFB1共同培养,定期测定培养液pH、菌丝体干重、黄曲霉孢子数、AFB1含量。结果黑曲霉与黄曲霉混合培养时,黄曲霉孢子数、AFB1含量均比单独培养的低,2组之间差异有统计学意义(P<0.05),抑制率达到68.06%~91.52%;加入黑曲霉后,AFB1含量降低,实验组与对照组之间差异有统计学意义(P<0.05),降解率为46.19%。结论黑曲霉既能抑制黄曲霉生长、产毒,又能降解AFB1。

| Abstract: | Objective To study the influence of Aspergillus niger on the growth of Aspergillus flavus and degradation of AFB1.Method Aspergillus niger was co-cultured with Aspergillus flavus and AFB1,respectively;pH,dry weight of mycelium,spores of Aspergillus flavus and content of AFB1 were determined every 3 days.Result Compared with the control group,the number of Aspergillus flavus spores and content of AFB1 were much less in competitive situation.There was a significant difference between the two groups(P<0.05) an... |
