This invention first found the nucleotide sequence of SEQ ID NO:1 from Anguilla anguilla and obtained bacteriostatic peptide with bacteriostasis activity through genetic engineering. The experiment proved that it could effectively inhibit the activity of Staphylococcus aureus and have the function of bacteriostasis. The suppression subtractive hybridization library was constructed by suppression subtractive hybridization. From this library, we found that this gene has a high frequency of occurrence, and through bacteriostasis experiments, it is found that the gene has the effect of inhibiting pathogenic bacteria and can be used as an antibiotic substitute to control the growth of pathogenic bacteria. After the gene was expressed by genetic engineering, the product was purified and removed by GST labeling. The results showed that the extract had bactericidal activity.

本专利技术涉及生物工程领域,特别涉及一种用于表达抑菌肽基因、抑菌肽及应用。
技术介绍
细菌性疾病对鳗鲡养殖业威胁较大,常造成巨大的经济损失。通常需要用抗生素对控制病害,但抗生素治疗具有很大的弊端,会发生在鳗鲡体内残留,病原生物耐药性增强,水域生态污染等问题。因此,迫切需要一种适用的抗生素替代物控制致病菌,对细菌性疾病进行防治。
