摘要
以侧耳(Pleurotus SP.)8405为实验菌株,研究了 L-肾上腺素对菌丝生长、子实体形成及多酚氧化酶、纤维素酶和呼吸强度的影响.实验结果表明:当培养基中 L-肾上腺素的浓度为5.5×10^(-7)～5.5×10^(-5)mol/L 时,侧耳8405菌丝生长快、生物学效率高,原基形成早,子实体数目和鲜重增加.当浓度为5.5×10^(-4)mol/L 时,对菌丝生长和子实体形成则有抑制作用.L-肾上腺素促进侧耳生长发育的效应同胞外多酚氧化酶、纤维素酶和呼吸强度之间有一定的联系.
The physiological effects of L-adrenaline on Pleurotus sp.8405 is studied.Various amounts of L-adrenaline are added to medium.The results indicate that the production and biological efficiency of mycelia,number and weight of fruiting bodies are greatly en- hanced by L-adrenaline at concentration of 5.5×10^(-7)～5.5×10^(-5)mol/L.These effects are associated with the increases of production and activity of polyphenol oxidase, cellulase production and respiration.The mechanism of L-adrenaline inducing the enzyme formation is discussed.
