摘　　要：废酵母是啤酒工业废水中的主要污染物。在常温下,用10%的淡盐水,从废酵母中提取核糖核酸和脱核酵母,回收率为3.3%～3.5%和65.2%～66.5%。对提取液进行预处理后,核糖核酸产品纯度大于90%。提取核糖核酸和脱核酵母后废水的BOD5和CODCr分别下降81%和78%以上。Spent yeast is the main pollutant in the wastewater from breweries.The recovery rates of ribonu-cleic acid and deribonucleic yeast from spent yeast at ambient temperature using10%dilute brine are3.3%~3.5%and65.2%?66.5%respectively.After the pre-treatment of the extract,the purity of the ribonucleic acid product exceeds90%.After the extraction of ribonucleic acid and deribonucleic yeast,the BOD 5 and COD Cr of the wastewater decrease by81%and78%respectively.
