中文摘要：据报道某些乳酸菌菌株能够抑制真菌生长并因此有作为生物防治剂的潜力。本研究从传统发酵的肯尼亚牛奶和玉米产品中分离出171株乳酸菌菌株，并检测其对产黄曲霉毒素的黄曲霉的抗性。结果表明某些LAB菌株可以用于控制食物中产黄曲霉毒素真菌的生长。正在进行进一步研究以确定发酵产品中潜在LAB菌株的功效。
外文摘要：Certain strains of lactic acid bacteria have been reported to inhibit fungal growth and may so be potential as biocontrol agents. In this study, 171 LAB strains were isolated from traditional fermented Kenyan milk and maize products and tested against aflatoxin-producing A. flavus fungi. The three LAB strains showing highest antifungal activity were identified as Lactobacillus plantarum. None of the strains were able to completely inhibit fungal growth under conditions favorable for fungi and suboptimal for LAB. These conditions probably reduced the growth and metabolic activity of some LAB isolates, as several growth-related aspects like production of antifungal biomolecules and other metabolites contribute to the inhibiting activity. The results suggest that certain LAB strains could be employed in food to control the growth of aflatoxigenic fungi. Further studies to establish the efficacy of the potential LAB strains in fermented products are in progress.
