摘　　要：以金枪鱼加工副产物为原料,研究其酶解液对顶头孢霉菌(Cephalosporiumacremonium)发酵产物的影响.以头孢菌素C(CPC)的产量为指标,通过正交实验和响应面方法,研究不同添加量的酶解液对顶头孢霉菌发酵产抗生素的作用,再利用气相-质谱联用仪(GC-MS)分析酶解液对顶头孢霉菌代谢物的影响.研究结果显示:在顶头孢霉菌的发酵培养基中,酶解液的添加量为30.86mL·L^-1时,CPC产量最高,为8.106g·L^-1,比未添加酶解液增加67.82%;酶解液的加入显著改变了顶头孢霉菌代谢物的种类和含量.The by-products of tuna were used as raw materials to study the effects of the hydrolysates on the fermentation products of Cephalosporium acremonium. Firstly, based on the yield of cephalosporin C(CPC), the effects of different amounts of hydrolysates on the production of antibiotics by C. acremonium were studied by orthogonal experiment and response surface method. The results showed that in the fermentation medium with the amount of hydrolysates being 30.86 mL·L^-1, the production of CPC reached a maximum of 8.106 g·L^-1. It was 67.82% higher than that without the hydrolysates. Further, the effect of the hydrolysates on the metabolites of C. acremonium was qualitatively and quantitatively analyzed by GC-MS. It was found that the addition of the hydrolysates significantly changed the species and content of the metabolites of C. acremonium. It was of great significance to improve the production of CPC and the comprehensive economic and environmental benefits of tuna processing that uses the resources of tuna processing by-products to develop fermentation industrial medium.
