In the present study, we have synthesized silver nanoparticles by a simple and eco-friendly method using unripe fruits of Solanum trilobatum. The aqueous silver ions when exposed to unripe fruits extract were reduced and stabilized over long time resulting in biosynthesis of surface functionalized silver nanoparticles. The bio-reduced silver nanoparticles(More)
In the present study, Hypocrea lixii SURT01, a isolate from poultry soil was subjected to 18s rRNA analysis was submitted to NCBI – Genbank. The strain was induced in minimal media which was found to produce the phytase enzyme. The characterization of extracellular phytase showed optimum activity at pH of 6.5 and temperature of 50oC after an incubation for(More)
Quorum sensing (QS) a cell density-dependent regulation of virulent bacterial gene expression which regulates pathogenesis of bacterial infection. QS is an effective strategy for the development of novel antimicrobial agents which can overcome antibiotic resistance. In the present study, anti quorum sensing activities of ethanolic extracts of medicinal(More)
In the present study, pesticidal activity of lectin against different life stages of major groundnut defoliator Spodoptera litura has been studied under in vitro condition. Lectin was isolated from pulp of banana and partially purified by silica gel and mannose – sepharose 4B affinity chromatography and the total yield of affinity purified lectin was about(More)
Irradiation of azido carbonyl compounds using UV light (≥310 nm) produced triplet alkyl nitrenes and aroyl radicals, which resulted in efficient cleavage of single strand DNA at pH 7.0. DNA cleaving ability of azido carbonyl compounds was found to be dependent on its concentration and substituents on its aromatic ring. Further, newly synthesized naphthalene(More)
Biofilm represents the most prevalent type of virulent factor of most of the pathogenic microorganism and involved in crucial development of clinical infection and exhibit resistance to antimicrobial agents. Now the biofilm is considered as major target for the pharmacological development of drugs. A biofilm serves to promote bacteria persistence by(More)
