Biosynthesis of silver nanoparticles using soil Actinomycetes Streptomyces sp

The use of nanoparticles is important, as several pathogenic microorganisms have developed resistance against various antibiotics. Since noble metal nanoparticles such as gold, silver and platinum nanoparticles are widly applied to human contacting areas, there is a growing need to develop environmentally friendly processes of nanoparticles synthesis using microorganism and plant extracts (Kathireswari et al. 2014). Both unicellular and multicellular organisms are known to produce inorganic materials either intra or extracellularly (Ahmad et al., 2003; Mann, 1993), often of nanoscale dimensions and of exquisite morphology and hierarchical assembly. While the use of non-biological methods involves abnormal reaction conditions, high energy input and hazardous materials. Utilization of biological systems as nanofactories, promises an environmental benign, clean, nontoxic and economical International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 4 Number 3 (2015) pp. 1073-1083 http://www.ijcmas.com
