1 抗菌肽
1.1 抗菌肽作用机制
本团队首次系统提出抗菌肽“源于胞内相近相容、高敏预警早期防御”高效入胞和“强穿膜、多靶点”低耐药机制和铁三角理论。正在进行抗菌肽作用病原菌细胞壁、细胞膜以及胞内大分子等靶标的挖掘和鉴定，并借助编辑/解码器等高通量智能筛选和解析低耐药强抗菌关键结构间的构效量效关系。
1.2 抗菌肽创制关键技术
在国内外率先建成抗菌肽现代生物制造体系，20/30m3规模先导产品生泰素发酵规模，蛋白表达量达3.14g/L，蛋白纯度>92%，日产能2kg/d，成本<70元/g。连续稳定运行七批次，制备纯品49kg，具抗菌肽生物工程路径走通并落地成功的重要技术标志和里程碑意义。目前正在（1）建立抗菌肽高产节能型制备体系，进行抗G+菌肽节能高产制备系统升级及抗G-菌肽高产制备系统的拓展；（2）抗菌肽修饰工程化研究（包括环化、纳米自组装、包被及适配体偶联等）；（3）抗菌肽成药性关键检测技术研究；（4）抗菌肽制剂开发研究。
1.3 抗菌肽应用
拓展抗菌肽对靶动物应用细分：防治奶牛乳房炎、母畜子宫内膜炎、家禽细菌性腹泻、水产细菌病、宠物等皮肤感染等。开展抗菌肽对上述适应症的靶动物药效、田间药效、安全性、药代动力学、残留消除等临床研究。
针对饼粕原料致敏蛋白含量高、发酵菌种多元、工艺粗放和质量不稳等瓶颈，筛评建立专用菌种库，创建致敏蛋白等抗营养因子分子检测方法、发酵工艺流程。制/修定首个发酵饲料原料标准《饲料原料发酵豆粕》，填补界定豆粕发酵程度和产品品质的空白，规范发酵工艺，对保障产品质量、满足细分需求、破解瓶颈问题具重要作用。
