Abstract

Cyanide is a known toxic chemical compound that has an adverse effect on living organisms. Nonetheless, it is one of the active reagents in industries such as mining, pharmaceutical, cosmetics, and food processing companies worldwide. The beneficiation of gold and other precious metals from ore generates great amount of cyanide-bearing contaminants, which is released into the environment. The abundance of cyanide contaminants from these industries have created public health concern since the inception of metal extraction from ore. There are strict regulations on the production, transportation, utilization, and disposal of cyanide-bearing contaminants worldwide. The conventional treatment of cyanide waste is either chemical or physical process. The use of these treatment processes has certain pitfalls like operational challenges, an increase in capital cost, and generation of secondary waste. A number of microorganisms have the potential to utilize cyanide as nitrogen and carbon source and transform it into ammonia and carbon dioxide. Biodetoxification might be efficiently, economically and environmentally safe to detoxify cyanide in contaminants and attractive alternative to conventional detoxification method like chemical or physical. This paper reviews the principles and methods of biodetoxification of cyanide contaminants found in the ecosystem.

氰化物污染物生物解毒的原理和方法

摘要

氰化物是一种已知的有毒化合物，会对生物体产生不利影响。尽管如此，它还是全球采矿，制药，化妆品和食品加工公司等行业中的活性试剂之一。矿石中金和其他贵金属的选矿会产生大量带有氰化物的污染物，这些污染物会释放到环境中。自从从矿石中提取金属以来，来自这些行业的大量氰化物污染物就引起了公众健康的关注。在全球范围内，对于生产，运输，使用和处置含氰化物的污染物都有严格的规定。氰化物废物的常规处理是化学或物理过程。这些处理程序的使用存在某些陷阱，例如操作挑战，增加了资本成本，并产生了二次废物。许多微生物具有利用氰化物作为氮和碳源并将其转化为氨和二氧化碳的潜力。生物解毒对污染物中的氰化物进行解毒可能是高效，经济和环境安全的，并且是传统解毒方法（如化学或物理方法）的有吸引力的替代方法。本文回顾了生态系统中氰化物污染物生物解毒的原理和方法。对污染物中的氰化物进行解毒在经济和环境方面都是安全的，并且是化学或物理等常规解毒方法的有吸引力的替代方法。本文回顾了生态系统中氰化物污染物生物解毒的原理和方法。对污染物中的氰化物进行解毒在经济和环境方面都是安全的，并且是化学或物理等常规解毒方法的有吸引力的替代方法。本文回顾了生态系统中氰化物污染物生物解毒的原理和方法。
