乳链菌肽发酵玉米浆—糖蜜培养基的优化制备（Optimization Corn Steep Liquor—Molasses Fermentation Medium for Nisin）
乳链菌肽 玉米浆 糖蜜 Box-Behnken设计
2009/8/11
采用单因素试验方法对影响乳链菌肽效价的培养基组分进行了考察。结果表明，影响乳链菌肽效价的主要因素为糖蜜、玉米浆、K2HPO4、MgSO4。在此基础上，采用Box-Behnken设计及响应面分析法确定主要影响因子的最佳质量浓度。结果表明，当玉米浆质量浓度为233g/L，糖蜜质量浓度为27g/L，K2HPO4质量浓度为5.0g/L，MgSO4质量浓度为0.1g/L时，乳链菌肽效价为2491.8IU/m...
