摘要

管理不同行业产生的角质废料正成为全世界关注的一个主要问题。每年有超过 10 亿吨的角蛋白废物被排放到环境中。尽管已经进行了一些试验,将这些废料转化为有价值的产品,但来自不同来源的大量角蛋白废料仍然是一种较少被开发用于制造有价值产品的生物材料。这表明,大量的角蛋白废料既没有得到妥善处理,也没有转化为可用产品,而是被丢弃到环境中,造成环境污染。由于这些废物与不同的病原生物一起进入土壤和水体,人类和其他大小动物受到不同疾病的影响。因此,有必要采用现代和生态友好的方法来处理这些废物并将其转化为可用产品。因此,本综述旨在简要概述利用产生角蛋白酶的微生物,通过生物方法降解角蛋白废物的情况。综述还重点介绍了角蛋白酶的实际用途,以及角质废料生物转化产品在不同应用领域的经济重要性。关于角蛋白废物的来源、处置机制、水解技术、潜在用途以及物理和化学性质,已经开展了多项研究。然而,关于将角蛋白废料用作角蛋白溶解微生物生长和从照相胶片和用过的 X 射线胶片中提取银的介质补充剂的信息却微乎其微。因此,本综述与其他类似的文献综述不同,它讨论了这些被忽视的问题。

Bioconversion of Keratin Wastes Using Keratinolytic Microorganisms to Generate Value-Added Products.

The management of keratinous wastes generated from different industries is becoming a major concern across the world. In each year, more than a billion tons of keratin waste is released into the environment. Despite some trials that have been performed and utilize this waste into valuable products, still a huge amount of keratin waste from different sources is a less explored biomaterial for making valuable products. This indicates that the huge amount of keratin waste is neither disposed properly nor converted into usable products rather thrown away to the environment that causes environmental pollution. Due to the introduction of this waste associated with different pathogenic organisms into soil and water bodies, human beings and other small and large animals are affected by different diseases. Therefore, there is a need for modern and ecofriendly approaches to dispose and convert this waste into usable products. Hence, the objective of this review is to give a concise overview regarding the degradation of keratin waste by biological approaches using keratinase producing microorganisms. The review also focuses on the practical use of keratinases and the economical importance of bioconverted products of keratinous wastes for different applications. Various researches have been studied about the source, disposal mechanisms, techniques of hydrolysis, potential use, and physical and chemical properties of keratin wastes. However, there is negligible information with regard to the use of keratin wastes as media supplements for the growth of keratinolytic microorganisms and silver retrieval from photographic and used X-ray films. Hence, this review differs from other similar reviews in the literature in that it discusses these neglected concerns.
