研究了硒对灵芝生长代谢的影响。考察了灵芝对硒的耐受浓度 ,硒对灵芝菌丝量、灵芝蛋白、灵芝多糖和矿物质代谢的影响 ,并探讨了硒对灵芝菌丝内部分酶代谢的影响。实验结果表明 :灵芝对硒的最大耐受浓度为 4 0 0 μg/ g,在硒浓度 4 0 0 μg/ g以内 ,硒对灵芝菌丝量、菌丝蛋白质及多糖的代谢没有明显的改变 ;除可明显增加矿物质锌的含量外 ,对铜、铁、锰和钙含量无影响 ;对菌丝内硒的富集作用是极其明显的 ,最高可达 70 0 0μg/ g左右 ;硒对灵芝酯酶同工酶、过氧化物酶同工酶没有结构上的影响 ,仅增加酶的活性。
The effects of selenium on the growth and metabolism of Ganoderma lucidum were studied. The effects of selenium on the concentration of selenium, selenium on Ganoderma lucidum mycelium, Ganoderma lucidum protein, Ganoderma lucidum polysaccharides and mineral metabolism were investigated. The effects of selenium on the enzyme metabolism in Ganoderma lucidum mycelia were also discussed. The experimental results showed that the maximum tolerance concentration of Ganoderma lucidum to selenium was 400 μg / g, while the selenium did not change the mycelium, mycelium protein and polysaccharide metabolism of selenium more than 400 μg selenium. In addition to significantly increase the content of mineral zinc, copper, iron, manganese and calcium content has no effect on the enrichment of selenium in mycelium is extremely obvious, up to 70 0 0μg / g or so; selenium on Ganoderma lucidum Esterase isozymes and peroxidase isozymes have no structural effect and only increase enzyme activity.
