Efficient photocatalytic degradation of industrial contaminants by Piper longum mediated ZnO nanoparticles.

Piper longum extract as a reducing agent in green synthesis method is used to synthesize ZnO nanoparticles (ZnO-NPs). The impact of the reductant on the structural, optical and surface morphological properties of ZnO-NPs can be analyzed. Piper longum extract has delicately tuned the band gap of ZnO-NPs.

Biogenic larvicidal formulation of metabolites from Steinernema saimkayi symbiont Xenorhabdus stockiae KUT6 against dengue vector Aedes aegypti.

To characterize the production and larvicidal activity of Xenorhabdus stockiae KUT6 Petroleum ether extracts from Luria Broth and induced Quorum sensing medium containing N-3- oxododecanoyl Homoserine Lactone inducer against dengue vector Aedes aegypti. The Galleria mellonella larvae were reared for the isolation of Steinernema saimkayi symbiont Xenorhabdus stockiae KUT6 from Cucumber field soil sample in NBTA. Then for the extraction of compounds the KUT6 strains were cultured in Luria Broth and Quorum Sensing optimized media using N-3-oxododecanoyl homoserine lactone inducer.

Cytotoxicity and Antibacterial Characteristics of Graphene-Oxide Nanosheets Toward Human Pathogens.

Nanomaterials show great opportunities in the development of electronics, biosensors, chemical and industrial applications. In this article, we are reporting the cytotoxicity and antibacterial characteristics of graphene-oxide (GO) nanosheets toward selected human pathogens. GO is prepared by using modified Hummers method.

Pseudomonas aeruginosa KUN2, extracellular toxins-A potential source for the control of dengue vector.

Background & Objectives: Dengue fever is one of the serious health disease transmitted by Aedes spp mosquitoes. The incidence of dengue has increased dramatically around the world in recent decades. Vector control is one of the important strategies practiced for the control of dengue fever.
