Cytotoxicity and hemostatic activity of chitosan/carrageenan composite wound healing dressing for traumatic hemorrhage.

Hemorrhage remains a big threat to trauma patients, especially in combat fields. Therefore, we formulated a biocompatible and biopolymer based chitosan/carrageenan composite dressing. This dressing was fabricated using freeze-drying that will serve as a promising material to promote hemostasis and tissue growth required during hemorrhage.

A novel green approach for dyeing polyester using glycerine based eutectic solvent as a dyeing medium.

In the past decade, water scarcity has become major concern and is going to be reality in future too. At the same time textile is necessity which needs a billion liters of fresh water for its processing. Out of this 16 % of water is only used for dyeing of textile materials.

Hemostasis and anti-necrotic activity of wound-healing dressing containing chitosan nanoparticles.

Necrotic tissues are the dead tissues present in the wounded areas, which need to be removed for rapid wound healing. Various biopolymer-based dressings have been exploited to heal infected wounds, but with limited success. In a quest to develop an effective and economic wound dressing, a biodegradable dressing containing chitosan nanoparticles has been successfully developed.

Synthesis of glycinamides using protease immobilized magnetic nanoparticles.

In the present investigation, was isolated from slaughterhouse waste and screened for the production of protease enzyme. The purified protease was successfully immobilized on magnetic nanoparticles (MNPs) and used for the synthesis of series of glycinamides. The binding and thermal stability of protease on MNPs was confirmed by FTIR spectroscopy and TGA analysis.

Bioscouring of cotton using lipase from marine bacteria Bacillus sonorensis.

Bioscouring refers to the enzymatic removal of impurities from cotton fabric, which imparts it with improved hydrophilicity for further wet processes. In the present study, the efficacy of lipase from newly isolated marine bacteria Bacillus sonorensis isolated from marine clams Paphia malabarica collected from Kalbadevi estuary, Mumbai, India, has been evaluated for scouring of cotton fabric and compared with conventional alkaline scouring of cotton. As a scouring agent for cotton fabrics, the lipase from B.

Characterization, kinetic, and thermodynamic studies of marine pectinase from Bacillus subtilis.

Characterization, kinetic and thermodynamic parameters of purified pectinase from Bacillus subtilis, isolated from a marine sediment sample collected from Chinchani beach at Tarapore, India, were studied. Marine pectinase produced under submerged growth conditions was purified by ammonium sulfate precipitation followed by gel filtration chromatography using DEAE cellulose. Partial characterization of the marine pectinase was carried out in terms of effect of pH, temperature, substrate concentration, and metal ions.
