| 摘 要： | 目的:明确培养猴头菌菌丝体时不同碳、氮源对多糖含量的影响。方法:用不同碳、氮源液体培养基对猴头菌进行液体浅层静置培养,用苯酚-硫酸法测定菌丝体中的多糖含量。结果:从菌丝体多糖含量角度考虑最佳碳源为淀粉,最佳氮源为豆腐渣;在淀粉用量为4.0%、豆腐渣用量为1.5%时得到的猴头菌菌丝体多糖含量高达162.17mg/g。结论:淀粉和豆腐渣能比常用碳、氮源大幅度提高液体培养猴头菌菌丝体的多糖含量,而且价格低、来源广,在生产上有着很好的推广应用前景。

| Abstract: | In order to exploit new carbon and nitrogen sources for Hericium erinaceus,effects of kind and amount of carbon and nitrogen sources on the content of polysaccharide in harvested mycelia and broth of Hericium erinaceus after 35-day liquid submerged fermentation.The phenol-sulfuric acid method was used to determine polysaccharide content.Results showed that the optimal carbon and nitrogen sources were starch and soybean dregs for polysaccharide production in Hericium erinaceus mycelia,respectively,and the co... |
