摘　　要：对三种药用真菌灵芝、灰树花和姬松茸的富锌能力进行比较,在三种药用真菌中灵芝对于锌的富集能力最强,锌浓度在240mg/L时,菌丝锌含量达到6.42mg/g,富集率达30.39%;灰树花的富集能力最弱,富集率最高仅为1.66%,锌浓度超过100mg/L后有明显的抑制作用;姬松茸的富集能力也较强,锌浓度在300mg/L时富集率达到最大7.53%,菌丝锌含量也达到了4.07mg/g,相比较而言灵芝与姬松茸较适合作为富锌的载体。In this article,we compared the ability of bioenrichment of Zinc of Ganoderma lucidum,Grifola frondosa and Agarics blazei Murill. The results showed that the capacity of Zn-accumulating of Ganoderma lucidum was the most strong,when the Znic added to the liquid medium is up to 240mg/L, the hyphae have the most Znic absorbance,which is up to 30.39% ;the capacity of Zn-accumulating of Grifola frondosa was the most weak,the most Znic absorbance of the hyphae is only up to 1.66%;the capacity of Zn-accumulating of Agarics blazei Murill was very strong,when the Znic added to the liquid medium is up to 300mg/L,the hyphae have the most Znic absorbance,which is up to 7.53%,so Ganoderma lucidum and Agarics blazei Murill can become organic carrier of Zn-enrichmento
