Description
技术领域
本发明提供了一种抗菌寡肽,特别是一种抗菌色天光肽及其制备方法和用途,属于生物技术领域。
背景技术
随着水产养殖的扩大化生产和水产养殖环境的不断恶化,一些水生性致病菌也呈现上升趋势,严重威胁着水产养殖户们的日常养殖,所以尽快研究出一种有效抑制水产致病菌的抗菌肽迫在眉睫。生物活性肽是涉及生物体内多种细胞功能的生物活性物质,在生物体内已发现几百种,不同的生物肽具有不同的结构和生理功能,如抗病毒、抗癌、抗血栓、抗高血压、免疫调节、激素调节、抑菌、降胆固醇等作用。寡肽具有生物活性,从食品中提取的蛋白质可能对人体有益。随着对蛋白酶解技术的研究逐渐深入,发现介于蛋白质和氨基酸间的肽类物质在食品方面具有极强的活性、多样性,更高的安全性。根据市场需求,寡肽类物质已近越来越多的被应用于药物、化妆品以及保健品等各个领域。海洋肽在海洋生物中广泛分布,所以以资源丰富的海洋麻虾为原料,提高产品的附加值。从海洋海洋麻虾中分离出抗菌肽,可作为食品配方中的功能性成分,能促进消费者健康,提高食品的货架期。因此,开发出安全的抗菌肽具有广阔的应用前景。
据调查研究发现,很多不同来源的水解蛋白都具有一定的抗氧化和抗菌能力,包括陆源蛋白,例如核桃蛋白、大豆蛋白、花生蛋白、玉米蛋白、油料种子蛋白、小麦醇溶蛋白和蚕丝蛋白等的水解物都具有一定的抗氧化性;乳清蛋白、卵白蛋白等蛋白水解产物具有一定的抗菌性。但是与海洋来源的蛋白相比,陆源蛋白受到地域、成本、气候的影响比较大。而且水解所用的酶绝大多数为市售商品酶,水解所得产物相差不大。目前市场上已经形成商品化的合成化学抗菌剂,例如无机抗菌剂银、锌和铜离子,具有较强的抗菌能力。有机抗菌剂主要是以季铵盐类、双胍类、醇类、含氯类盐酸、(异)噻唑类、有机卤化物、有机金属化合物、酚类、吡啶类、咪唑类卤代烷基类、碘化物等。然而,以上的抗菌剂具有潜在的风险,易从环境中析出,易产生耐药性,分解产物有毒,安全性没有完全确定,应严格限制其使用。因此,开发安全的、天然的、能够代替传统抗生素药物的抗菌肽具有广阔的应用前景应用价值。
