藏茶贮存过程中真菌种群的鉴定

Identification of Fungal Populations during the Storage Period of Tibetan Tea

为探索藏茶贮存过程中品质变化与微生物种群的关系,对雅安藏茶贮存过程中存在的真菌种群进行了分类学地位鉴定。结果表明,藏茶贮存过程中主要存在的真菌种群为曲霉属的黑曲霉、青霉属的光孢青霉菌、娄地青霉菌和巴恩正青霉菌以及根霉属的根霉菌5大类种群。这些微生物均可直接或间接地影响藏茶贮存过程中的品质形成。

The fungal populations in the storage period of Tibetan tea were identified to study the relationship between tea quality and microbe species populations.The results showed that there were 5 main species populations of Aspergillus（Aspergillus niger）,Penicillium（Penicillium glabrum,Penicillium roqueforti,Baen penicillium）,and Rhizopus（Rhizopus） in the storage period of Tibetan tea.These microbes could affect quality formation of Tibetan tea during the storage period directly or indirectly.
