不同培养条件对双孢蘑菇菌丝生长的影响

Effects of Different Culture Conditions on Mycelial Growth of Agaricus bisporus

为筛选适宜的北方双孢蘑菇菌株培养条件及提高双孢蘑菇菌种质量,研究了双孢蘑菇菌株在不同温度、光照和氮源条件下其菌丝生长情况。结果表明:双孢蘑菇As2796菌丝生长的适宜温度为20~30℃,最适温度为25℃;避光和光照条件下双孢蘑菇As2796菌丝均可生长,避光处理略好于光照处理;以硫酸铵、蛋白胨、酵母粉和尿素为氮源的培养基上As2796菌丝均可生长,其中最适合的氮源为蛋白胨。

In order to screen suitable culture conditions of Agaricus bisporus strains and improve the quality of Agaricus bisporus strains,the mycelial growth of Agaricus bisporus under different temperatures,light and ni-trogen sources was studied.The results showed that the suitable temperature of the mycelia growth of Agaricus bisporus As2796was20to30℃,the optimum temperature was25℃;The mycelia of Agari-cus treatment;As2796mycelium could grow on ammonium sulfate,peptone,yeast powder and urea as nitrogen source,and the optimum nitrogen source was peptone.
