摘要
通过对面包酵母培养过程的解析,确定了分批培养中达到较大比生长速率和良好发酵活力的初糖浓度为24.6g/L;残糖控制浓度为4.0~6.0g/L.采用连续培养方法作为研究手段,得出以糖蜜为限制性碳源基质的面包酵母培养动力学为u=0.611s/(4.206+s)。提出了以最大转化率为目标并能获得优良发酵活力的面包酵母流加培养模式,并通过实验证明了培养模式的适用性。
ased on the process analysis of baker's yeast culture,the initial sugar
concentration(24.6g/L) andthe residual sugar concentration(4.0~6.0g/L) for larger special
growth rate and better fermentativeactivity were determined in batch culture. Kinetics of
baker's yeast μ=0.611s/(4.026 +S) was ob-tiuned by continuous culture technique. With the
maximum yield as objective function , the fed-batchmedel for baker's yeast with good
fermentative activity was established , and its application was sup-posed theoretically and
proved experimentally.
