【中文摘要】 對繡球菌301、302進行紫外線誘變處理,以生長速度為指標進行初篩,再通過深層發酵進行復篩,綜合分析菌絲體的生長量和胞內外多糖的產量,選出301-3、302-2為優選菌株。研究不同碳、氮源對誘變株301-3菌絲體生長和多糖產量的影響,認為淀粉、麥芽糖是較為合適的碳源;玉米粉和麩皮是較為合適的氮源。對碳氮源正交試驗,確定最佳的培養基組成為:淀粉2.0%、麥芽糖0.4%、玉米粉0.6%、麩皮0.6%。

【英文摘要】 Two strains of Sparassis Crsipa,301 and 302 were treated with UV induced irradiation,then the strains were firstly screened by the index of its growth speed.After submerged liquid fermentation,we re-screed 301-3,302-2 as fine strains when analyzing the amount of their mycelia growth and the yield of intracellular and extracellular polysaccharides.Through the study on the effect that the nitrogen and carbon sources had on strain 301-3,we found that amylum and maltose were appropriate carbon sources for strain 301-3,while corn flour and bran were optimum nitrogen sources.By orthogonal test on the carbon sources and nitrogen sources,we got the suitable ingredients of culture medium for strain 301-3 as follows: amylum2%,maltoes0.4%,corn flour0.6% and bran0.6%.
