One step green synthesis of larvicidal, and azo dye degrading antibacterial nanoparticles by response surface methodology.

The present study explored the one step extracellular green synthesis of Iron oxide (FeO) and manganese oxide nanoparticles (MnNPs) using aqueous extract of Acorus calamus rhizome. The organic chemicals including polyphenol compounds responsible for bio-reduction and stabilization from the polyphenol enriched microwave irradiated aqueous extract of Acorus calamus were studied using GC-MS analysis. Further, their synthesis conditions were optimized using response surface methodology (RSM) and central composite design (CCD) using three variables.

Simultaneous production of commercial enzymes using agro industrial residues by statistical approach.

Background: Simultaneous production of commercial enzymes using agro-industrial residues by statistical approach is an important perspective in an industrial point of view. Despite the advantages of statistical methods optimization, the report on simultaneous production of pectinase and amylases are limited. The accumulation of agro-industrial residues causes serious environmental problems; however, citrus peel can be the important substrate for various enzymes production, including pectinase.
