中文摘要：前期研究中，我们挑出了三株细菌，巨大芽孢杆菌KU143、Microbacterium testaceum KU313和Pseudomonas protegens AS15，作为有效的抗储藏稻谷黄曲霉的生物防治剂。本研究评估了菌株产生的挥发物对储藏稻谷黄曲霉生长及黄曲霉毒素产生的抑制作用。据我们所知，用巨大芽孢杆菌和P. protegens的挥发物抑制稻谷中黄曲霉和黄曲霉毒素的产生，本报道尚属首例。
外文摘要：In our previous study, three bacterial strains, Bacillus megaterium KU143, Microbacterium testaceum KU313, and Pseudomonas protegens AS15, were selected as effective biocontrol agents against Aspergillus flavus on stored rice grains. In this study, we evaluated the inhibitory effects of the volatiles produced by the strains on A. flavus growth and aflatoxin production on stored rice grains. The three strains significantly reduced mycelial growth of A. flavus in dual-culture assays compared with the negative control strain, Sphingomonas aquatilis KU408, and an untreated control. Of these tested strains, volatiles produced by B. megaterium KU143 and P. protegens AS15 markedly inhibited mycelial growth, sporulation, and conidial germination of A. flavus on agar medium and suppressed the fungal populations in rice grains. Moreover, volatiles produced by these two strains significantly reduced aflatoxin production in the rice grains by A. flavus. To our knowledge, this is the first report of the suppression of A. flavus aflatoxin production in rice grains using B. megaterium and P. protegens volatiles.
