Correlation analysis between filamentous fungi and chemical compositions in a pu‐erh type tea after a long‐term storage

摘要

Storage environment caused the difference between Jinhua Pu‐erh tea (JPT) and General Pu‐erh tea. In this study, fungal flora and chemical compositions were analyzed. The results showed that storage environment caused significant (  p Aspergillus niger, , , and were isolated from Pu‐erh teas and identified based on colony characteristics and ITS, β‐tubulin, and calmodulin gene sequences, respectively. , , and were dominant fungi in JPT and generated macroscopic yellow cleistothecia after a long‐term storage. Correlation analysis showed that dominant fungi exhibited significantly (  p A. pallidofulvus, A. sesamicola, and and their effects on given chemical compositions.
