前驱分子式：CAS号：性质：又称前体，前驱或前身。（一）催化剂所含成分系来源于不同原料，而制备催化剂某一成分所用的原料称为母体。如镍催化剂的制备，骨架镍的母体是镍铝合金，沉淀镍的母体为NiCO3或Ni(OH)3，等，两者经分解制得NiO经还原后活性在较大差别。同样母体NiCO3，其晶粒越大，产生的NiO晶粒也较大，若母体缺陷较多，分解产生的NiO缺陷也较多。（二）前体是一类特殊的产品促进剂，加入发酵培养基中的前体，可在基本保持本身结构单元情况下直接用于产物合成，从而使发酵液中产物的产量有较大的提高。针对不同的发酵产品寻求适宜的前体，是提高发酵产量的重要措施。前体在使用时常采用少量多次添加到培养基中，以避免过高浓度可能对微生物产生的毒性，或造成不必要的浪费。
