Abstract
The synthesis of silver nano particles was done by using the polysaccharide from leaf extract of Heritiera fomes and AgNO3. Thus synthesized Ag-nanoparticles are characterized by using UV- VIS spectrum band at 446 nm. Here, the polysaccharide acts as reducing and also stabilizing agent. The synthesized Ag-nanoparticles were found as very effective an antimicrobial agent against some important human pathogens such as S. typhi. S. typhimurium, Pseudomonas sp. These Ag-nanoparticle can also reduce the microbial load by destroying the microorganisms present in sewage water .
