Protease production byStaphylococcus epidermidisand its effect onStaphylococcus aureusbiofilms

Immobilization of Alkaline Protease produced from Bacillus Licheniformis PTCC1331 on Calcium Alginate (Its effect on enzymatic activity)

Alkaline Protease enzyme produced from Bacillus Licheniformis PTCC1331 in optimum Condition(Temperature 37 ?C, 150 rpm, PH=10), is immobilized in different concentrations of Sodium Alginate using entrapment method, to increase its thermal resistance in detergents, and its activity is measured thereafter. Maximum enzymatic activity of 46 was obtained in 2%w/v Sodium alginate solution. Investiga...

E¡ectof salicylic acid on invasionof humanvascularendothelial cells byStaphylococcus aureus

Invasion of vascular endothelial cells by Staphylococcus aureus is associated with diverse complications and recurrent infection. Little is known about the effect of salicylic acid, the major metabolite of aspirin, on the interaction between S. aureus and vascular endothelial cells. We examined the adhesion of S. aureus strain 8325-4 cultured with or without salicylic acid to human umbilical ve...

Transmissible Gastroenteritis Virus Papain-Like Protease 1 Antagonizes Production of Interferon-β through Its Deubiquitinase Activity

Coronaviruses (CoVs), such as human coronavirus NL63 (HCoV-NL63), severe acute respiratory syndrome CoV (SARS-CoV), murine hepatitis virus (MHV), porcine epidemic diarrhea virus (PEDV), and Middle East Respiratory Syndrome Coronavirus (MERS-CoV), encode papain-like (PL) proteases that inhibit Sendai virus- (SeV-) induced interferon (IFN-β) production. Recently, the crystal structure of transmis...

Screening of Thraustochytrids for alkaline protease production

Production of alkaline protease from Cellulosimicrobium cellulans

Cellulosimicrobium cellulans is one of the microorganisms that produces a wide variety of yeast cell wall-degrading enzymes, β-1,3-glucanase, protease and chitinase. Dried cells of Saccharomyces cerevisiae were used as carbon and nitrogen source for cell growth and protease production. The medium components KH2PO4, KOH and dried yeast cells showed a significant effect (p<0.05) on the factorial ...
