Production and characterization of new fibrinolytic protease from Mucor subtill...

Fibrinolytic enzymes have received attention regarding their medicinal potential for thrombolytic diseases, a leading cause of morbidity and mortality worldwide. Various natural enzymes purified from animal, plant and microbial sources have been extensively studied. The aim of this work was to produce fibrinolytic protease by solid state fermentation using agro industrial substrates. Rhizopus arrhizus var. arrh...

Interactions between glycerol, PEG-200 and (NH4)2 SO4 in the stability of heter...

Cutinases (EC 3.1.1.74)are versatile enzymes that have hydrolytic activity on various esters [1]. The spacial structure and the catalytic site of the enzymes can be protected by chemical additives to promove the stability of the activity [2, 3]. The goal of this work was to improve the stability of a recombinant cutinase produced by Escherichia coli.

Antimicrobial and anti-adhesive potential of biosurfactants produced by Candida...

Evaluation antimicrobial and antiadhesive properties of the biosurfactant lunas...

Different groups of biosurfactants exhibit diverse properties and display a variety of physiological functions in producer microorganisms; these include enhancing the solubility of hydrophobic/water-insoluble compound, heave metal binding, bacterial pathogenesis, cell adhesion and aggregation, quorum sensing and biofilm formation. Candida sphaerica was grown in a low cost medium, consisting of distilled water s...

Antimicrobial and anti-adhesive potential of a biosurfactant Rufisan produced b...

In the last years, researches developed with biosurfactants for application in the medical area have been revealing the promising biological activities of these biomolecules. In this work the antimicrobial and anti-adhesive properties of a biosurfactant Rufisan isolated from the yeast Candida lipolytica UCP 0988, growth in a medium supplemented with ground nut refinery residue was determined against several mic...

Chromium (VI) ion adsorption features of chitosan film and its chitosan/zeolite...

This research evaluated the importance of the adsorption properties of chitosan a chitosan/zeolite conjugate film for the removal of Cr(VI) ions from solutions in the 5–260 mg/L concentration range, when the pH was adjusted to 4.0 and 6.0. The uptake capacities of the films formed by chitosan and by the chitosan/zeolite conjugate were calculated by mass balance. The equilibrium isotherms were fitted to the Lang...

Chromobacterium violaceum as a potential biosurfactant‐producing microorganism

Chromobacterium violaceum is a Gram‐negative bacterium found in the soil and water in tropical and sub‐tropical environments. Its complete genome sequence revealed wide varying alternative pathways for energy generation, complex and extensive systems for stress adaptation, motility and widespread utilization of quorum sensing for control of its inducible systems. Biosurfactants are amphiphilic compounds produce...

Environmental and industrial application criteria to establish the microbial cu...
