Abstract

ABSTRACT: The application of microbes to synthesize metallic NPs is due to their increased capability to survive at maximum concentrations of metallic ions. The gold nanoparticles are used as the catalytic agent in the degradation of organic dyes, bioremediation, and antibacterial and antimicrobial effects. Despite the fact that the production of metal gold nanoparticles is relatively new, the relationships amongst microorganisms and metals have been thoroughly documented. In the subject of bioremediation, the capacity of bacteria to accumulate metals has also been acknowledged. Recently, the diversity of microorganisms has been used as factories for fabricating AuNPs both intracellularly and extracellularly. Microbial cells, upon treatment with gold salts, synthesize gold nanostructures, which are further isolated and purified using varied methodologies to acquire AuNPs. Control over the size and shape of AuNPs can be achieved by manoeuvring the main growth parameters.
金纳米颗粒的微生物合成及其催化应用
摘要:微生物在最大浓度金属离子环境下的生存能力增强,因此应用于金属纳米粒子的合成。金纳米颗粒在有机染料的降解、生物修复、抗菌和抗微生物等方面被用作催化剂。尽管金属金纳米颗粒的生产相对较新,但微生物与金属之间的关系已被彻底记录。在生物修复方面,细菌积累金属的能力也得到了承认。最近,微生物的多样性已被用作细胞内和细胞外制造aunp的工厂。微生物细胞经金盐处理后,可合成金纳米结构,并使用各种方法进一步分离和纯化以获得aunp。通过控制主要的生长参数,可以控制aunp的大小和形状。
