| 摘 要： | 以生物量为指标,研究了对桦褐孔菌液体深层发酵影响较大的主要因素,即温度、发酵时间、初始pH、接种量、摇床转速,并运用中心旋转组合设计法对发酵条件进行了优化,确定了其最佳范围。结果表明,5个因子对生物量的影响由大到小依次为初始pH、发酵时间、接种量和摇床转速、温度,而当温度、发酵时间、初试pH、接种量和摇床转速分别为28.6℃,125 h,5.9,10.5%和135r/min时,获得的生物量最大,为22.91 g/L。

| Abstract: | Different factors,including temperature,fermentation time,initial pH,inoculum and rotary speed were studied comparatively using biomass as a director during the submerged fermentation of Phaeoporus obliquus liquor,and were optimized using central composite rotatable design(CCRD).The results indicated that the five factors have different effects on biomass,with a order from high to low: initial pH,fermentation time,inoculum and rotary speed,temperature.The maximum biomass(22.91 g/L) was acquired under the conditions of temperature 28.6℃,fermentation time 125 h,initial pH5.9,inoculum 10.5%(v/v)and rotary speed 135 r/min. |
