STUDY ON THE STATISTICAL METHODS TO OPTIMIZE SCPFERMENTATION MEDIUM OF ASTRAGATUS SINICS JUICE
数理统计方法优化单细胞蛋白发酵培养基研究

Orthogonal test and central combination design was coupled to optimize SCPfermentation mediam of Astragatussinics juice. The experiment results showed that, theoptimum medium was 2.3% initial glucose, 0.16% yeast extract, KH_2PO_4 0.2%, MgSO_40.05%, the cell density was 10.46g/L, the biomass yield factor was 0.55 and the substrateconversion ratio was 83%. The study process also illustrated that the statistical methoddecreased experimental times compared with conventional method and became simplified.
