采用PCR-DGGE技术研究了川南与川北两个酒厂酱香型白酒糙沙糟真菌群落的差异，结果发现，所有酒醅样品均出现4～11条较清晰的条带，其中第2号、第4号、第6号、第7号条带在所有样品中均有检出，且优势度较高，川南糙沙糟的条带丰度整体高于川北；所有样品真菌群落生物多样性指数都在0.49～1.27之间，不同地域酒醅差异较大，川南糙沙糟真菌多样性整体高于川北；不同地域之间的相似性指数均在0.43以下，表明不同地域之间的真菌群落差异性较大。

The difference in fungal communities of fermented grains(after the secondary sorghum input) of Jiangxiang Baijiu(liquor) collected from different areas (south Sichuan and north Sichuan) were analyzed through PCR-DGGE technology. The results showed that, all fermented grains samples showed 4 to 11 clear bands;among them, No.2, No.4, No.6, and No.7 bands were detected in all samples and showed higher domi-nant degree, and band abundance in samples from south Sichuan was higher than that from north Sichuan;the diversity indexes of fungal commu-nities of all samples were between 0.49 and 1.27, and there was some difference among samples from different areas, samples from south Sichuan had more fungal communities than samples from north Sichuan; the similarity indexes of samples from different areas were below 0.43, indicat-ing that there was obvious difference in fungal communities of fermented grains from different areas.
