- 摘要:
- 以平菇菌种上分离的细菌、真菌为研究对象,制备不同质液比的大蒜、乙酸乙酯提取液,采用抑菌圈法研究了大蒜提取液对平菇生产中的竞争性杂菌的抑制作用,采用菌丝生长速度法测定了大蒜提取液对平菇菌丝生长的影响。结果表明:以质液比1∶2提取48 h的大蒜提取液对竞争性杂菌的抑制效果明显,在加入1%(质液比1∶2)提取液pH 8~9培养基上既不影响平菇菌丝生长,又能较好地抑制各类杂菌。
- Abstract:
- With bacteria and fungus that seperated from Pleurotus ostreatus as research object,different ratio of guality to liquid of garlic and ethyl acetate was prepared.The inhibition effect of garlic extract on competitive microbes in mushroom production was studied by inhibition zone method.The influence of garlic extract on Pleurotus ostreatus mycelium growth was also analyzed through mycelial growth rate method.The results showed that garlic and ethyl acetate (w/v) 1∶2 extracted for 48 h,which inhibition effect was remarkable.Added garlic extract 1% of medium content in the culture medium of pH 8~9,which didn’t affect the growth of Pleurotus ostreatus mycelium,but could enhance the inhibition effect on various competitive microbes.
