双孢菇栽培过程中铜迁移规律的研究

Study on the Migration of Copper during the Cultivation of Agaricus bisporus

摘要: 为了探究在双孢菇栽培过程中，重金属铜在培养基质与双孢菇子实体内的迁移情况，从而为双孢菇的食用安全性提供科学依据，为开发利用双孢菇富集重金属铜的能力奠定科学基础，本研究以双孢菇作为研究对象，测定从双孢菇培养全过程中发酵料、各次培养料基质以及双孢菇子实体中的铜的含量，获得在双孢菇栽培过程中铜的迁移规律。研究发现，发酵料中的铜含量与其发酵程度有关，经过发酵后的培养基质中的铜被双孢菇吸收利用，双孢菇中的自身菌丝体的活力对双孢菇菌体内的铜含量有所影响。

Abstract: In order to explore the migration of heavy metal copper in the culture medium and the fruit bodies of Agaricus bisporus in the process of cultivation of Agaricus bisporus, provide a scientific basis for the food safety of Agaricus bisporus and lay a scientific basis for the development and utilization of the ability of Agaricus bisporus to enrich heavy metal copper, this research takes Agaricus bisporus as the research object to measure the content of copper in the fermented material, the various culture substrate and the fruit body of Agaricus bisporus in the whole process of Agaricus bisporus’s cultivation, and the copper migration rule during the cultivation of Agaricus bisporus is obtained. The study finds that the content of copper in the fermentation material is related to the degree of fermentation. After fermentation, the copper in the culture medium is absorbed and used by Agaricus bisporus. The activity of the self-mycelium in the Agaricus bisporus has an effect on the copper content in the Agaricus bisporus.
