应用传统的普洱熟茶渥堆方法进行发酵,研究分析普洱茶渥堆发酵过程中嗜热微生物的种类,应用测序技术对分离的微生物进行了鉴定。每天取样,进行微生物的分离、纯化及鉴定,并对分离出来的几种嗜热霉菌在不同温度、不同pH条件下培养,观察其生长情况。对普洱茶发酵过程中的微生物进行全面分析,运用分子生物学方法对分离的微生物进行鉴定。发现了普洱茶渥堆发酵过程中起重要作用的嗜热微生物,为揭示普洱茶高温发酵的机理奠定了基础。
Thermophilic fungi were isolated and identificated by the method of sequencing during traditional fermentation of puer tea. Sampling were carried out every day. Many types of microorganisms including thermophilic fungi were purified and Identified. Isolated thermophilic fungi were cultured at different temperatures and different pH, the growth state of thermophilic microorganisms were observed. This article showed a comprehensive analysis of microorganisms during the fermentation of puer tea, and identified the isolated microorganisms using molecular biology method. Thermophilic microorganisms which play an important role during the fermentation were discovered, it laid the foundation to reveal the mechanism of Puer tea fermentation at high temperature.
