Abstract:
Taking Cordyceps militaris as test material,different concentrations of zinc were added to the culture medium to analyze the effects of zinc on the growth and biological activity of mycelia and fruiting bodies.Zinc content of mycelium and fruiting body was determined by Rhodamine B spectrophotometry,the polysaccharide content of stator substance was measured by anthrone-sulfuric acid,and the reducing sugar content of stator substance was determined by DNS method,in order to provide reference for the cultivation of zinc-rich Cordyceps militaris.The results showed that zinc had a certain effect on the mycelium and fruiting body,and the growth was inhibited when the concentration was too high.The most suitable medium for the growth of Cordyceps militaris was 678 mg?kg-1基基.At this concentration,zinc had a great effect on the fruiting body,with maximum dry weight of 3.56 g,the polysaccharide content of 7.32%,zinc enrichment ratio of 6.45%.
