摘　　要：对红发夫酵母利用黄浆水发酵制备虾青素的条件进行了研究,结果表明:黄浆水发酵的部分适宜条件是:采用新鲜黄浆水,在初始pH6.0条件下,接种量4%,发酵约72h。发酵约62h达到最高总氮去除率23.0%,发酵约72h达到最高COD去除率43.4%。Astaxanthin as a kind of natural pigment, is widely used in food and pharmaceutical industry. This paper introduces a method for its preparation from the effluents of squeezing process of the products made from soybean, in which Phaffia rhodozyma is used for fermentation. After the fermentation COD and total nitrogen of the effluent are degraded.
