【摘要】 红茶菌是一种由醋酸菌和酵母菌共生发酵得到一种共生体。本文利用传统红茶菌膜作为发酵剂,探讨了不同茶汁浓度、碳源、氮源、起始pH值、不同离子强度和培养温度、培养方式对红茶菌发酵最终pH值和菌膜量的影响。结果表明:乙醇和蛋白胨的加入、浅盘培养对发酵成膜有显著增长效果,而最终pH值的变化与膜形成不呈正相关。更多还原

【Abstract】 Kombucha is a kind of symbiosis with yeast and acetic acid bacterium. In this paper, effects of ultimate pH value and cellulosic pellicle membrane were studied with difference tea-brothes, carbon sources, nitrigen sources, initial pH values, ion intensities, temperatures, cultivating modes in tea fungus fermentation with traditional cellulosic pellicle as fermentation starter. The results were showed as following: supplement of ethanol and peptone, pan cultivation have prominence effects on forming cellulosic pellicle, the final pH value has negative correlation with forming cellulosic pellicle.更多还原
