摘　　要：将假丝酵母接种在添加亚硒酸钠的培养液中进行驯化,以大曲丢糟为主要原料,以富硒假丝酵母为菌种进行富硒饲料蛋白的发酵生产,通过正交试验得到最佳的饲料生产工艺条件为:亚硒酸钠添加量为0.75 mg/kg,富硒假丝酵母接种量为15%,发酵时间为4 d。该富硒饲料粗蛋白和有机硒含量分别达到了17.8%、0.17 mg/kg。The Candida mycoderma was cultured in the culture solution with additive of Na2SeO3. The Se-enriched Candida mycoderma was used to ferment yeast distiller＇ s grain to produce Se-enriched feed protein. The best process conditions obtained by orthogonal test were as follows： the adding amount of Na2SeO3 0.75 mg/kg, the adding amount of Se-enriched Candida mycoderma 15 % and the fermentation time d d. The contents of crude protein and organic-Se were up to 17.8% and 0.17 mg/kg respectively.
