以糖化能力较强的根霉Q303为菌株，通过单因素和正交试验对根霉麸曲种曲培养工艺进行优化。结果表明，影响根霉麸曲质量的因素依次为：水分含量＞装载量＞培养时间。根霉麸曲种曲的最佳培养工艺条件为：培养温度32.5 ℃、培养时间60 h、装载量15 g/500 mL、水分含量53.3 %（8 mL），为中试生产提供有力的数据支撑和理论指导。 |

The culture of the seed of Rhizopus bran starter was optimized by single factor test and orthogonal experiments with Rhizopus oryzae Q303 of strong saccharifying power as the strain. The results suggested that, the factors influencing the quality of Rhizopus bran starter ranked in decreasing sequence as moisture content＞loading capacity＞culture time. The optimum culture conditions were summed up as follows: culture temperature was at 32.5 ℃, culture time was 60 h, loading amount was 15 g/500 mL, and moisture content was 53.3 %(8 mL). This study had provided data support and theoretical guidance for pilot production.
