摘要
葡萄酒活性干酵母属于活性干酵母系列,在我国尚未生产。本工作利用优良性能的葡萄酒干酵母菌株,采用我们自行发展的碳氮源流加工艺制出了在规格上及质量上可比拟于国外同类商品的产品。本文公布了糖流加累积曲线作为菌体生长量的参据。
Active dry yeast for wine belongs to ADY series.It has not yet been produced hitherto in China.We adopted a proper selected neutral strain to attain commercial scale production of ADY for wine.Using our own fed-batch method for sugar and nitrogen feeding,the products can be used as a substitute for imported commodity.By the fermentation process derived by us the sugar assimilation rate reached 0.5,the mean specific growth rate was about 0.14 with a four times multiplication to initial inoculation and the shelf life of products was about 6 months.The open published sugar adding curve vs time can be treated as a clue for biomass production.
