胡萝卜素产生菌红酵母R-93培养基营养条件研究
A Study on the Optimized Culture Medium for the Carotin Producer Rhodotorula Glutinis R-93
【摘要】 采用均匀设计的方法,优化胡萝卜素产生菌酵母R-93发酵培养基的营养条件.经回归分析和发酵试验得出最佳培养基配方(%):蔗糖为1.0;蛋白胨为1.253(NH4)2SO4为1.0;KH2PO4为0.28;MgSO4·7H2O为0.025.在此条件下,发酵指数可达到0.262g(干菌体)·(L·h)(-1).
【Abstract】 The nutritional condition of culture medium for Rhodotorula glutinis R-93 as carotin producer can be optimized by adopting the method of even design. The optimum prescription of culture medium for this carotin producer is obtained by regression analysis and fermentation test as follows: 1. 0 % sucrose, 1. 25 %peptone, 1. 0 % (NH4)2SO4,0. 28 % KH2PO4, 0. 025 % MgSO4· 7H2O. Under such condition, a fermentation index of 0. 262 g dried cells per liter per hour can be attained.
