Abstract:

Nanotechnology, an attractive branch of science deals with smaller particles with incredible efficiency. The applications of nanoparticles were widely distributed in all fields of science to enhance the reaction with ease. Despite of chemical and physical method of synthesis, biological methods has gained importance due to its less toxicity and cost efficiency. In the present study, silver nanoparticles (Ag NP’s) were synthesized using the culture supernatant of AcinetobacterindicusVLE-1 isolated from paper mill effluent. The synthesized nanoparticles were characterized using UV- visible spectroscopy, FTIR, XRD, SEM and TEM analysis. Biogenic Ag NP’s were evaluated for its antagonistic ability against selected pathogenic bacterial strains such as Bacillus cereus, Streptococcus pyogenes, Shigella dysentriae, Escherichia coli and Proteus vulgaris. Maximum zone of inhibition was recorded against Escherichia coli and Shigella dysentriae when compared with the control. The nanoparticles were determined for its larvicidal activity against Culex mosquito larvae at various concentrations. Larvicidal activities were observed to be directly proportional to the concentration of biogenic Ag NP’s.
