Abstract

本发明公开了一种富硒白灵菇液态发酵培养基，这种培养基由3.2～3.3％葡萄糖；1.5～1.8％酵母膏；0.2～0.25％KH2PO4；0.1～0.12％MgSO4；0.0025～0.003％Na2SeO3和适量的蒸馏水组成。通过富硒白灵菇液态深层培养，菌丝生物量可达1.336g/100ml，富硒率可达7.51％。

Description

一种富硒白灵菇液态发酵培养基
技术领域
本发明涉及食用菌培养基，特别涉及的是一种富硒白灵菇液态发酵培养基。
背景技术
目前作为有机硒制品富硒食用菌的研究和开发倍受关注，但是关于白灵菇富硒液态深层发酵培养的报道甚少，且液体发酵诸因素对菌丝富硒生长的影响尚未见报道。以白灵菇为富硒的载体，将亚硒酸钠添加到培养基中，通过富硒白灵菇液态深层培养，富硒率可达7.51％。
发明内容
本发明的目的是提供的一种富硒白灵菇液态发酵培养基，克服了传统固态培养基菌丝生长慢、富硒率低等缺点。
提供的一种富硒白灵菇液态发酵培养基，其原料由以下重量百分比的组分组成：
葡萄糖：3.2～3.3％；
酵母膏：1.5～1.8％；
KH2PO4：0.2～0.25％；
MgSO4：0.1～0.12％；
Na2SeO3：0.0025～0.003％；
蒸馏水：适量；
以上各组分之和为100％，其特征在于：在上述配料中添加有0.0025～0.003％Na2SeO3。
通过富硒白灵菇液态深层培养，菌丝生物量可达1.336g/100ml，富硒率可达7.51％。
具体实施方式
实施例
葡萄糖：32.7g/L；
酵母膏：16.9g/L；
KH2PO4：2.15g/L；
MgSO4：1g/L；
Na2SeO3：30μg/ml；
添加蒸馏水至1000ml。
通过富硒白灵菇液态深层培养，菌丝生物量可达1.336g/100ml，富硒率可达7.51％。
