摘要

The paper presents isolation and identification of silver resistant micro-organisms from different samples like soil and industrial effluent. Isolated silver resistant microbes were further tested for their capacity to synthesize nanoparticles by growing them in suitable nutrient medium with varying concentrations of silver salt. Nanoparticle production was further confirmed by UV visible spectrophotometry. All nanoparticle producing strains were identified by conventional biochemical tests and molecular identification technique of 16s rDNA sequencing. Silver nanoparticles produced by the identified isolates were extracted and characterized by particle size analyzer to comprehend their size and identify their future applications. Extracted nanoparticles were impregnated on the natural fibers like jute, coconut, and banana. The coated fibers were characterized by studying their surface properties under scanning electron microscope and their antimicrobial activity was also tested.
