Ag-nanoparticles based on polysaccharide isolated from the leaves of mentho piperita and their study on microbes and comparison with ciprofloxacin

Abstract: 

In modern research, the field of science is the most interesting areas for its wide application in chemistry, electronics, ecology, and medicine  as well chemists, biologists / microbiologists for their commercial demand as in biological fields. Economically preparation of silver nano particles using green synthesis path having biological entities are gradually increases. Now a day’s Ag-nano particles based on synthetic polysaccharide or plant or animal polysaccharide is unique. In the investigation, synthesis of Ag-nano particles were prepared by using polysaccharide, isolated from leaves of Mentha piperita and characterized by using UV-VIS spectrum band at 432 nm. Here, the polysaccharide acts as reducing and also capping agent. The synthesized Ag-nano particles were found as very effective against some important human pathogenic bacteria such as E. coli ATCC 25922, K. pneumoniae ATCC 70063, S. typhi MTCC 734 and also effective against Agrobacterium tumefaciens, which is responsible for crown gall disease in plants. These Ag-nano particles were very good effective against E. coli ATCC 25922, K. pneumoniae ATCC 70063, S. typhi MTCC 734 compared with antibiotic Ciprofloxacin. These Ag-nano particles have also sporocidal activity. These Ag-nano particles can also reduce the microbial load in sewage water.
