微生物酶技术的进步，在这种情况下是角蛋白分解蛋白酶，为低能耗技术提供了相当大的机会，用于将家禽羽毛从强污染物生物转化为营养升级的富含蛋白质的牲畜饲料。提供了关于自然界中微生物角质分解和感染（皮肤真菌病）的最新信息的概要，以强调利用生物技术改善羽毛营养的可行性，并作为传统水热处理的替代方法。支持的证据，营养（氨基酸）升级续集羽毛的各种微生物处理，并从大鼠和小鸡的生长研究中获得的积极成果已经提交。本文最后提出了应用生物技术改善羽毛（和其他角蛋白）作为家畜饲料的营养状况的途径。(C)1998爱思唯尔科技有限公司版权所有。
Advances in microbial enzyme technology, keratinolytic proteases in this case, offer considerable opportunities for a low-energy consuming technology for bioconversion of poultry feathers from a potent pollutant to a nutritionally upgraded protein-rich feedstuff for livestock. A compendium of recent information on microbial keratinolysis in nature and infection (dermatophytoses) has been provided as underscoring feasible harnessing of the biotechnology for nutritional improvement of feathers, and as an alternative to conventional hydrothermal processing. Supporting evidence of a nutritional (amino acid) upgrading sequel to diverse microbial treatments of feathers, and positive results obtained from growth studies in rats and chicks have been presented. The paper concludes with suggestions for avenues of application of biotechnology for nutritional improvement of feather (and other keratins) as feedstuffs for livestock.
