【摘要】 通过比较碳源、氮源以及装液量对红酵母RY 2 0 0 1摇瓶培养的生物量影响 ,得出最适合其生长的碳源、氮源、装液量 ;同时通过正交实验得到它们的最适比例。实验结果表明最适培养条件 :NaNO3 2 % ,蔗糖6 % ,MgSO40 .6 % ,酵母膏 1.5 % ,2 5 0mL锥形瓶装培养基 5 0mL ,最适培养温度 2 8℃ ,15 0r/min ,振荡培养 36h左右达到最高生物量 2 1.6 7g/L。更多还原

【Abstract】 The paper reports the effects on the biomass for the shake cultivation of Rhodotorula RY-2001 by the use of different carbon sources,nitrogen sources and medium volumes.The optimized conditions for the growth of Rhodotorula RY-2001 were found accordingly.The result shows that the biomass,21.67g/L,will be the top on conditions of NaNO-3 2%,Sucrose 6%,MgSO-4 0.6%,Yeast extract 1.5%,28℃,and 36hrs with shake cultivation(150r/min).;更多还原
