摘要
目的研究漳州市郊农村土壤的产毒霉菌生态。方法采样检验漳州市24个自然村48件土壤样品 ,用孟加拉红琼脂平板涂布法进行霉菌计数并分类鉴定。结果48件土壤样品的霉菌数量未见异常。检出34属3357株霉菌 ,镰刀菌和青霉为优势菌属 ,木霉、拟青霉和枝孢霉也是常见菌属。在检出的4株黄曲霉菌株中2株为产毒株 ,黄曲霉毒素B1 产量分别为6、7ng/g,均不产生黄曲霉毒素B2、G1、G2。2株杂色曲霉均为产毒株。结论漳州市郊农村土壤黄曲霉在菌相中所占比例极低 ,而且产毒能力极弱 。
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.
