- Abstract
Aflatoxin is the most powerful carcinogen and highly toxic mycotoxin known in nature. It can cause serious toxin pollution to agricultural products' foods and fodders' and is extremely harmful to human and animal health. For aflatoxin pollution' the emphasis is on the control of source' and biological control is favored by scientists because of its advantages of environmental protection and ecological safety. According to the morphology' color and appearance of microbial colonies isolated from maize kernels' 300 bacterial strains were obtained from main maize-producing areas including Tangshan City' Handan City' Shijiazhuang City and Cangzhou City. Two biocontrol bacterial strains (B120 and B65) having a strong control effect on aflatoxins were screened. After identification by molecular biolog and physical and chemical properties' the two biocontrol bacterial strains were identified as Bacillus amyloliquefacieus. Their effects on spore germination' mycelial growth and toxin degradation of Aspergillus flavus were investigated. The results showed that strains B120 and B65 could significantly inhibit the spore germination and mycelial growth of A. flaw and reduce aflatoxin production. This study provides a new way to prevent and control the pollution control of aflatoxins in agricul- tura3products
