家禽业的持续发展导致生产设施和加工厂提供的废物数量增加。禽肉的加工产生了大量的固体废物，如羽毛、内脏、骨头和到达时死亡。利用酶将这些副产品生物转化为具有更高价值的材料是一种有趣的策略。酶可用于将家禽排泄物转化为饲料和化肥。动物副产物的水解还可以产生生物活性多肽，这些生物活性多肽是在体内发挥生理作用的重要分子，如抗氧化剂、血管紧张素转换酶(ACE)抑制活性和二肽基多肽酶-IV(DPP-IV)抑制活性。因此，家禽副产物水解物显示出作为功能成分的潜力。本文综述了用于家禽废弃物生物转化的微生物酶类，如蛋白酶、脂肪酶、复合酶制剂，特别是用于羽毛生物转化的角蛋白酶。本文对角蛋白水解酶的产生、纯化及性质进行了讨论。进一步研究的主要领域是角蛋白酶的大规模生产和纯化，以及从家禽粪便中生产生物活性分子的有效方法的开发。(C)2015爱思唯尔有限公司。保留所有权利。
The continuous growth of poultry industry results in an increased amount of waste provided from both production facilities and processing plants. The processing of poultry meat results in massive quantities of solid waste as feathers, viscera, bones, and dead on arrival. The use of enzymes for bioconversion of such byproducts into materials with increased value is an interesting strategy. Enzymes can be useful to convert poultry waste into feed and fertilizers. The hydrolysis of animal byproducts can also generate bioactive peptides, which are important molecules that may exert physiological effects in vivo, as antioxidant, angiotensin-I converting enzyme (ACE)-inhibitory and dipeptidyl peptidase-IV (DPP-IV)-inhibitory activities. Thus, poultry byproduct hydrolysates show potential for use as functional ingredients. This review presents an overview on useful microbial enzymes for bioconversion of poultry waste, such as proteases, lipases, combined enzyme preparations and, especially, keratinases for bioconversion of feathers. A discussion about production, purification and properties of keratinases is presented. Main areas for further studies are large scale production and purification of keratinases, and development of effective processes for production of bioactive molecules from poultry waste.
