摘要:本试验以双孢蘑菇As2796为研究对象,对双孢蘑菇液体菌种固态化工艺进行了研究。通过测定固态化菌种萌发时间、菌丝生长速度、菌丝长势、机械强度,确定优化后包埋剂组成为:海藻酸钠3.5%、硅胶4.0%、脱脂乳粉2.0%、谷氨酸钠4.0%、羧甲基淀粉钠2.0%,滴落于2.5% CaCl2溶液中凝固。在此条件下制备的固态化菌种,萌发时间34 h,菌丝生长速度为4.9 mm/d。出菇数据表明,固态化菌种23 d即可满瓶,产量达到14.72 kg/m2

AbstractThe solid-state technology of liquid spawn of Agaricus bisporus As2796 was studied in this study. According to the germination time, mycelial growth rate, mycelial growth potential and mechanical strength, the optimized embedding agent group was: sodium alginate 3.5%, silica gel 4.0%, skimmed milk powder 2.0%, sodium glutamate 4.0%, carboxymethyl starch sodium 2.0%, dropped into 2.5% CaCl2 solution for solidification. Under these conditions, the germination time of solid-state strains was 34 h, and the growth rate of mycelium was 4.9 mm/d. The data of mushroom production showed that the solid-state strain could be filled in 23 days, and the yield reached 14.72 kg/m2.
