摘要: 抗菌肽在原核生物与真核生物中都存在。它们分子量小、结构紧密、热稳定性好。通过基因工程可以改进其性质,优化分离过程可以降低生产成本,使把抗菌肽开发成天然食品防腐剂成为可能。

Abstract: Antimicrobial peptides are found both in prokaryotes and eukaryotes.They possess low molecular weight and are characterized by compact structures,thermal stability and potent antimicrobial activity.Since these peptides are directly gene-encoded,it is possible to modify their stl’ucture by mutagenesis to produce structure analogues with an expanded spectrum of antimicrobial activity.Futhemore.the production of these peptides could enable yield improvement to make accessible t’or industrial application and to reduce the processing costs by using optimized isolation procedures.They might be useful as etyective natural food preservertives because of their good properties.
