Optimisation of garlic mustard oil macerate with respect to its antifungal activity against MTCC 183 and molecular docking of the volatile compounds with N-myristoyltransferase.

infections are widespread in people and cause cutaneous and systemic infections. Optimisation of garlic mustard oil macerate (GMM) based on antifungal activity against was done using agar diffusion method. Upon vapour diffusion assay, the volatile organic compounds of both GMM and MO were found to eradicate .

A novel reusable PAni-PVA-Amylase film: activity and analysis.

Alpha-amylase was immobilized onto polyaniline-polyvinyl alcohol (PAni-PVA) film by cross linking with glutaraldehyde. The activity yield and immobilization efficiency was calculated as 13.58% and 30.

Possible protection of silver nanoparticles against salt by using rhamnolipid.

Rhamnolipid (RL) from Pseudomonas aeruginosa was dissolved in distilled water with concentration equivalent to its critical micelle concentration (CMC). Silver nanoparticles (SNP) synthesized in the RL colloid were found to be stable for more than 1 month. Further, after 1 month when the SNP in RL colloid (SNPRL) were exposed to NaCl solution it took about 60 mg/ml as compared to 2 mg NaCl/ml in the case of SNP colloid for degrading silver nanoparticles.

Hair waving natural product: Dillenia indica seed sap.

Knowing keratin is the main component and mechanical strength of hair a study was performed to evaluate whether Dillenia indica seed sap can affect molecular strength of hair or not. In the present study the human hair collected from barber shop waste were subjected to purified sap for 12 h and then analysed using Fourier transform infrared spectroscopy (FTIR) for documenting evidence for keratin degradation. Further the deterioration was confirmed by thermo gravimetric analysis (TGA) and scanning electron microscopy (SEM).

Isolation and immobilization of aroid polyphenol on magnetic nanoparticles: enhancement of potency on surface immobilization.

Five polyphenolic compounds were isolated from four aroid species [using High Performance Liquid Chromatography (HPLC)] and identified using Fourier Transform Infrared (FTIR) spectroscopy and Nuclear Magnetic Resonance (NMR) analysis. The compounds benzoic acid, caffeic acid, coumaric acid, ferulic acid and syringic acids were immobilized on magnetic nanoparticles (MNPs) using poly(ethylene glycol) (PEG) as linker polymer. The obtained PEG-MNP-polyphenol trios were characterized using transmission electron microscopy (TEM) and FTIR.

Immobilizing silver nanoparticles (SNP) on Musa balbisiana cellulose.

Cellulose from Musa balbisiana was purified. A part of it was dispersed in distilled water using ultrasonication. The silver nanoparticles (SNP) were synthesized in the colloidal cellulose solution and stability of the nanoparticles was tested using UV-Vis spectrophotometer.

Bio-plastic (P-3HB-co-3HV) from Bacillus circulans (MTCC 8167) and its biodegradation.

Polyhydroxyalkanoates (PHAs) are naturally occurring polyesters synthesized by bacteria for carbon and energy storage and it has commercial potential as bioplastic. The bacterial species Bacillus circulans MTCC 8167, isolated from crude oil contaminated soil, can efficiently produce medium chain length polyhydroxyalkanoates (P-3HB-co-3HV) from cheap carbon sources like dextrose. The molecular mass of P-3HB-co-3HV was reported as 5.

Enhancing the stability of colloidal silver nanoparticles using polyhydroxyalkanoates (PHA) from Bacillus circulans (MTCC 8167) isolated from crude oil contaminated soil.

Polyhydroxyalkanoate (PHA) was produced by growing Bacillus circulans (MTCC 8167) in the specific detection medium. The identification of the polymer as PHA was confirmed by fluorescence microscopy. The PHA was purified and characterized using FT-IR.

'Poly(ethylene glycol)-magnetic nanoparticles-curcumin' trio: directed morphogenesis and synergistic free-radical scavenging.

Research on curcumin (polyphenol derived from the rhizome of herb Curcuma longa) has occupied a unique niche owing to its distinctive properties, unique molecular architecture and multi-potent efficacies, particularly in the bio-medical domain with recent interest in material science. In the present study, conjugation of curcumin onto biocompatible poly(ethylene glycol)--templated magnetic iron oxide nanoparticles (MNP) (2-5 nm), prepared through a simple wet chemical route is reported along with modulation of the activity of the partners. Statistical optimization, using response surface methodology, of sonication parameters (8 min, 0.

Biocompatible novel starch/polyaniline composites: characterization, anti-cytotoxicity and antioxidant activity.

Starch/polyaniline composites have been synthesized using oxidative polymerization of polyaniline in an aqueous dispersion of starch isolated from Colocasia esculenta corm. Scanning electron micrographs reveals the growth of polyaniline over the surface of the starch granules. DPPH scavenging and haemolysis prevention assay have been performed to estimate the antioxidant activity and cytotoxicity of the composites.

Ultrasonication: enhances the antioxidant activity of metal oxide nanoparticles.

The present work is a modification for Serpen et al.'s method for antioxidant activity determination for insoluble materials with special reference to metal oxide nanoparticles. As reported in our former publications the mixing procedures were followed as mentioned by Serpen et al.

Nickel oxide nanoparticles: a novel antioxidant.

We investigated a novel inorganic (nickel oxide) nanoparticles as a potential antioxidant in the biosystems. The particles were synthesized using self-propagating high-temperature synthesis (SHS) method at 650 degrees C. The antioxidant property of the nickel oxide particles was investigated in an in vitro system, using modified DPPH method for insoluble solid materials.
