摘　　要：研究了添加不同浓度的锌盐对硫磺菌菌丝生理活性的影响。结果表明,加锌培养前后,培养液的电导率变化与pH值变化呈一定的反比关系;低浓度的锌可促进硫磺菌菌丝生长,锌浓度高至500mg/L后则抑制菌丝生长,在培养液中添加锌,可显著提高菌丝的含锌量,当锌浓度为400mg/L时,单位菌丝的含锌量最大,为88.5μg/g干菌丝;随着锌浓度的增加,菌丝可溶性蛋白、多糖含量的变化均呈先上升后下降的趋势,可溶性糖含量的变化则与之相反。The effects of different concentrations of zinc treatment on the physiological activity of Laetiporus sulphureum Mycelium were studied. The results showed that before and after zinc adding,the change trend of medium conductivity and pH value was inverse. Low concentration of zinc could promote mycelium growth ,while the high concentration of 500mg/L would inhibit. The addition of zinc in the culture medium could increase the zinc content in mycelium significantly. When the concentration of zinc was 400mg/L,the largest zinc content was 88.5μg/g dry mycelium. With the increase of zinc concentration, soluble protein changed as consistent with polysaccharide,while the change of soluble sugar was the opposite.
