摘要
酵母细胞能够将无机态微量元素铁、锌转化成为有机态的微量元素。采用富集培养方法 ,从 2 2株酵母菌菌株中筛选出 2株能同时富集高含量铁、锌的酵母菌 ,对其铁、锌含量进行了测定。结果表明 :铁、锌含量分别达到 6~ 8mg/ g和 4~ 5mg/ g ,适宜的铁盐、锌盐为硫酸盐 ,其添加的离子浓度为 6 0~ 12 0mg/kg。
Inorganic trace element iron, zinc can be enriched into organic forms by yeast Two strains which can enrich high content of iron and zinc simultaneously were selected from 22 strains of yeast by using culture enrichment technique. Iron and zinc contents in the two strains were about 6~8?mg/g and 4~5?mg/g, respectively Sulphate of Fe and Zn were ideal forms of the two elements with optimal concentration in the culture medium being 60~120 mg/kg
