Abstract:
Objective To study the ecological characteristics of toxigenic fungi in soil of the suburban villages of Zhangzhou, Fujian. Methods 48 soil samples were collected from 24 natural villages in Zhangzhou and cultured in bengal rose agar plate, then the fungal count and species identification were carried out. Results The numbers of fungi in unit area in 48 soil samples were in the normal rang. 3357 strains of 34 fungal genera were found in sampled soil samples. Fusarium and Penicillium were the dominant genera, as well as Trichoderma, Parcilomyces, Cladosporium which were commonly detectable. 4 strains of Aspergillus flavas were found, 2 of them were toxigenic. Aflatoxin B 1 production were 6?7 ng/g respectively and they didnt produce AFB 2? AFG 1? AFG 2. 2 strains of A. versicolor both produced sterigmatocystin. Conclusion Aspergillus flavus showed lower proportion in mycoflora and weaker capability for producing aflatoxins in soil of suburban villages of Zhangzhou. This data obtained could be used as the basis for agriculture areal programme.
