摘　　要：在酵母菌中筛选铁的本底水平及生物量较好的优良菌株,以甜菜糖蜜为主要原料,加入适当的无机铁及营养盐,经发酵培养获得高铁营养酵母产品,酵母细胞铁的含量为2352mg/kg,蛋白质的含量为53 38%(w/w),干酵母产率为2 70%(w/v)。Yeast with concentrated iron and fine biomass has been selected as the test strain It uses molasses as the raw material. Suitable amounts of inorganic iron and nutrient salt are added. After fermentation and culturing, the iron content of the yeast cell is 2 352 mg/kg, protein over 5338%The yield of the iron yeast is over 27%
