摘要:

为研究不同碳源对双孢蘑菇商业菌株A15和W192菌丝生长及胞外酶活性的影响,了解其对碳水化合物的生理需求。以不同单糖、双糖、低聚糖、多糖为试材,测定双孢蘑菇的菌丝生长速度、菌丝生物量、胞外木质纤维素酶活性。结果显示,单糖中葡萄糖、果糖对W192菌丝生物量的促进作用比A15显著,使A15菌丝生物量增加7.7%~30.8%和23.1%~38.5%,使W192的菌丝生物量增加21.1%~36.8%和26.3%~57.9%。海藻糖、蔗糖、淀粉、纤维素提高了菌丝生长速度,海藻糖、麦芽糖、蔗糖、低聚木糖、淀粉、纤维素增加了菌丝生物量,0.5%纤维素使A15和W192分别增加3.3、2.3倍。分别有10个碳源提高A15和W192的漆酶、C1及Cx活性,12个碳源均抑制A15的β-GC活性,除木聚糖、木质素外,其余10个碳源可以提高W192的β-GC活性。研究发现,双糖(海藻糖、麦芽糖、蔗糖)、低聚木糖、多糖(淀粉、微晶纤维素)对促进双孢蘑菇菌丝生长作用显著,且促进作用优于单糖,微晶纤维素对双孢蘑菇菌丝生长的促进效果最好,W192可能比A15有更高的碳源需求或耐受性。研究旨在为两个菌株的栽培生理研究积累数据,可以基于W192和A15的偏好,设计不同碳源原料的培养基配方。

Abstract:

The effects of different carbon sources on the mycelium growth and extracellular enzyme activities of A15 and W192 were investigated to understand the physiological requirements of carbohydrates of the two commercial Agaricus bisporus strains. Using different monosaccharides, disaccharides, oligosaccharides and polysaccharides as test materials, the mycelial growth rate, mycelial biomass and extracellular lignocellulase activities were determined. Glucose and fructose increased the mycelial biomass of A15 by 7.7%-30.8% and 23.1%-38.5%, respectively, while that of W192 was increased by 21.1%-36.8% and 26.3%-57.9%, respectively. Trehalose, sucrose, starch and cellulose increased the growth rate of mycelia; trehalose, maltose, sucrose, xylo-oligosaccharide, starch and cellulose increased mycelial biomass, among which 0.5% cellulose increased the mycelial biomass of A15 and W192 by 3.3 and 2.3 times, respectively. 10 carbon sources increased laccase, C1 and Cx activities of A15 and W192, respectively. All the 12 carbon sources inhibited β-GC activity of A15. However, in addition to xylan and lignin, the β-GC activity of W192 was increased. Trehalose, maltose, sucrose, xylo-oligosaccharide, starch and microcrystalline cellulose promote mycelial growth significantly. W192 may have higher carbon source demand or tolerance than A15.
