摘　　要：采用不同微量元素分步骤添加方法,以防培养基产生沉淀;并用原子吸收分光光度计测定铬、锌浓度,用原子荧光光度计测定硒浓度。结果表明:直投型酸乳发酵剂和保加利亚乳杆菌都具有一定的富集能力,在各自的最佳富集盐浓度下,直投型酸乳发酵剂富集能力大大高于保加利亚乳杆菌。The method that different trace elements are added into MRS medium in different time is used to prevent precipitation. The results shown that LB and DVS both have certain enriching ability of Se, Cr and Zn when two or three kinds of the trace elements are enriched. But the trace elements enrichment amount of DVS was greatly higher than that of LB.
