摘　　要：采用平板培养和液体培养的方法研究不同碳源及其浓度对黄伞菌丝生长和胞外多糖产量的影响。结果表明:适宜黄伞菌平板培养菌丝的碳源及其浓度为:果糖2.5%、麦芽糖3.0%、葡萄糖3.0%、乳糖3.0%、红糖2.5%、蔗糖2.5%;最适宜黄伞菌液体培养菌丝体的碳源为3.0%的葡萄糖,最适宜黄伞菌产生胞外多糖的碳源为2.0%的麦芽糖。This study was designed to understand the effects of different carbon sources and its various concentrations on growth of Pholiota adiposa and exopolysaccharide production in plate culture and liquid culture. Results indicated that the optimal carbon sources and their concentrations for mycelia growth in plate culture were 3.0% fructose, 2.5% maltose, 3.0% glucose, 3.0% lactose, 2.5% brown sugar and 2.5% sucrose; glucose was determined to be the optimal carbon source for mycelia growth in liquid culture and its optimal concentration 3.0%; and the optimal carbon source for exopolysaccharide yield was maltose and its optimal concentration 2.0%.
