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 5338%The yield of the iron yeast is over 27%
