To establish the substrate specificity o f the thioglucoside glucohydrolase myrosinase (EC 3.2.3.1), this enzyme was purified to homogeneity from light-grown cress (Lepidium sativum L.) seedlings by Sephadex gel filtration. Red Dye and anion exchange (FPLC M ono Q) chro­ matography, and preparative isoelectric focusing. Hydrolytic activity was shown toward only 4 o f the 29 synthetic and natura...

Saffron essential oil has a pleasant aroma and medicinal activities. However, it is sensible into the environmental condition. Therefore, it should be protected against unwanted changes during storage or processing. Encapsulation is introduced as a process by which liable materials are protected from unwanted changes. In the present study, different ratios (0:100, 25:75, 50:50, 75:25, and 100:0...

Nonfermenting gram negative bacilli (NFGNB) cause serious infections in immuncompromised and hospitalized patients. They cause fatal lower respiratory tract infections in patients admitted to ICU’s. The appearance of metallo ß-lactamases (MBL) genes and their spread among bacterial pathogens is a matter of concern. The present study was undertaken to know the prevalence of MBL producing NFGNB.N...

BACKGROUND AND OBJECTIVES Carbapenem resistant Pseudomonas aeruginosa is a serious cause of nosocomial infections. The main purpose of the study is to determine the prevalence rate of imipenem resistant Pseudomonas aeruginosa carrying metallo-ß-lactamase (MBL) genes. MATERIAL AND METHODS 236 Pseudomonas aeruginosa isolates were collected from teaching hospitals of Ahvaz University of Medical ...

The prophenoloxidase activating system (proPO-AS) in fresh water crab, Barytelphusa cunicularis is localized in the hemocytes. Using anticoagulant (EDTA-Citrate buffer) it was possible to isolate intact hemocytes without causing extensive degranulation & subsequent clotting. Activation and conversion of prophenoloxidase to phenoloxidase(PO) was carried out by serine proteinase. PO was found to ...
