Antimicrobial activity of silver nanoparticles synthesised by using microbial biosurfactant produced by a newly isolated MDU6 strain.

Microbial biosurfactants has evolved as green molecules and their chemical diversity has gained momentum in recent time not only in the field of environmental and industrial sectors but also in the pharmaceutical sector. In this study, an effort was made for the biosynthesis of silver nanoparticle (AgNPs) having antimicrobial and non-cytotoxic activities with the help of microbial biosurfactant extracted from a novel strain MDU6 (Genbank accession no. MH382951) from petroleum oil logged soil sample in Dibrugarh, Assam.

Biosynthesis of AgNPs using aqueous leaf extract of and their anti-inflammatory effect on carrageenan-induced paw edema in male Wistar rats.

Silver nanoparticles (AgNPs) were synthesised from aqueous Ag nitrate through a simple, competent and eco-friendly method using the leaf extract of as reducing as well as capping agent. Ultraviolet-visible absorption spectroscopy was used to confirm the formation of AgNPs which displayed the substantiation of surface plasmon bands at 425 nm. The NPs were also characterised using Fourier transformer infrared spectroscopy, X-ray diffraction method, transmission electron microscope and zeta potential.

Evaluation of in vitro and in vivo anti-urolithiatic activity of silver nanoparticles containing aqueous leaf extract of Tragia involucrata.

The present investigation is focused on exploring the anti-urolithiatic potential of aqueous leaf extract of Tragia involucrata (TIA) and its silver nanoparticles (AgNPs) and to quantify the total phenol, flavonoid, terpenoid and sterol contents present in TIA. Quantification results suggested TIA to be a rich source of phenol, flavonoid and terpenoid and less of sterol content. The AgNPs were synthesized by a simple green method using aqueous extract of T.

Microemulsion synthesis of silver nanoparticles using biosurfactant extracted from MKVIT3 strain and comparison of their antimicrobial and cytotoxic activities.

In the present study, an efficient biosurfactant producing bacterial strain MKVIT3 was isolated from an oil logging area in Vellore district of Tamil Nadu, India. Liquid chromatography-mass spectrometry (LC-MS/MS) analysis was performed for the identification of different congeners present in the extracted biosurfactant. The column purified biosurfactant was used to stabilise the formation of silver nanoparticles (NP) using borohydrate reduction in reverse micelles.

Antiurolithiatic activity of ethanol leaf extract of Ipomoea eriocarpa against ethylene glycol-induced urolithiasis in male Wistar rats.

Objective: The objective of this study was to investigate the prophylactic and curative effect of the ethanol leaf extract of Ipomoea eriocarpa (Convolvulaceae) (IEE) in ethylene glycol-induced urolithiasis in rats.

Materials And Methods: Thirty male Wistar rats were divided into five groups (n = 6). All the groups received stone-inducing treatment till 28(th) day, comprising 1% ethylene glycol (v/v) with 1% ammonium chloride (w/v) for 4 days, followed by 1% ethylene glycol alone in water, except Group I (Control).
