发酵床腐殖质代料培养大球盖菇菌丝的适合性评价

Suitability Evaluation of Stropharia rugoso-annulata Mycelium Culture with Microbial Fermentation Bed Humus as Substitute Material

发酵床腐殖质是现代化畜牧养殖业中产生的废弃物,为避免造成环境污染,必须多方式加以资源化再利用。本研究以不同比例的发酵床腐殖质作为培养大球盖菇菌丝的主要基质原料,比较其菌丝形态和生长速度,对发酵床腐殖质代料培养大球盖菇菌丝的适合性进行评价。结果表明:完全替代麦麸用料组(处理Ⅰ)的菌丝由于生长细弱、稀疏,不适宜作为替代料配方使用;完全替代木屑用料组(处理Ⅱ)菌丝生长缓慢;有添加麦麸的其他配方,菌丝均洁白、较浓密,菌丝生长情况与CK组相当。鉴于相同的菌丝生长情况,可继续优化发酵床腐殖质的替代应用方法,选择最佳替代比例进行大球盖菇菌丝培养。

The microbial fermentation bed humus is the waste produced in the modernized animal husbandrybreeding industry.In order to avoid environmental pollution,it must be reused with multimode as resourcerecovery.The mycelium morphology and growth speed were compared,and the suitability of Stropharia rugosoannulata mycelium culture with microbial fermentation bed humus as substitute material was evaluated,bytaking microbial fermentation bed humus with different proportion as the main substrate raw material.Theresults showed that the mycelium of group Ⅰ,in which the material wheat bran was completely replaced,wasgracile and sparse,so the microbial fermentation bed humus was not suitable as a substitute material; themycelium of groupⅡ,in which the material sawdust was completely replaced,grew slowly; the mycelium of theother formula that adding the wheat bran was all pure white and thickening,the growth situation of themycelium was the same as that of group CK.In view of the same growth situation of the mycelium,theapplication method of microbial fermentation bed humus as a substitute material could be further optimized toselect the best substitution proportion to culture the mycelium of Stropharia rugoso-annulata.
