抗菌肽在农业和食品工业上的应用

抗菌肽是免疫学的研究热点,具有防效好、抗菌谱广、无污染等特点,是传统化学杀虫剂和抗生素的有力新型替代物,也可改善杀虫剂和抗生素长时间滥用导致的害虫和病原体抗性。人们也已经掌握了许多基因编码的动植物抗菌肽,并以此成功设计了新型杀虫剂和药物,许多都已生产和应用。虽然抗菌肽也有正常机体认可及应用技术等问题亟待解决,但是其在农业和食品工业中的成功应用,预示着抗菌肽的前景会很广阔。

Application of antimicrobial peptides in agriculture and food industry

Antimicrobial peptides have captured the attention of researchers in recent years because of their efficiency in fighting against pathogens.Antimicrobial peptides are under consideration as new substitutes for conventional pesticides and antibiotics.Many plants and animals have been manipulated with antimicrobial peptide-encoding genes and several pesticides and drugs have been produced based on these peptides.Such strategies and products may still have a long way to go before being confirmed by regulatory bodies and others need to surmount technical problems before being accepted as applicable ones.In spite of these facts,several cases of successful use of antimicrobial peptides in agriculture and food industry indicate a promising future for extensive application of these peptides.
