Background : Cholesterol oxidase (CHO) is an enzyme that catalyzes cholesterol oxidation and produces hydrogen peroxide (H2O2). This enzyme is produced by certain pathogenic and non-pathogenic microorganisms and is a commercially important enzyme in the world which has found wide application in various industries. The aim of the study was to isolate native bacteria producing CHO and their ident...

Background and Objectives: Nowadays, extruded snacks are the most common form of meals; however, their high amount of salt and fat leads to increase disease risk. Their coating would be a proper carrier for probiotics and has an appropriate potential for enhancement of the nutritional properties of puffed snacks. In this research, production of symbiotic snack coating by probiotic bacteria, as ...

aroa is an important gene which produces aromatic amino acids essential for bacterial life. the sequence of this gene was shown to be different in bacteria, so the purpose of this study was sequencing of aroa gene in native e. coli o78: k80 to determine the putative differences between this strain and other e. coli o78: k80 strains in gene bank. pcr was used to amplify aroa gene in native e. co...

A high-affinity surface receptor for human plasmin has been reported on certain group A streptococci. To map the region of the plasmin molecule that binds to the bacterial receptor, isolated domains of plasmin were tested for their ability to inhibit the binding of intact radiolabeled plasmin to receptor-positive bacteria. Complete inhibition of binding of labeled plasmin to bacteria by isolate...

Display of peptides on the surface of bacteria offers many new and exciting applications in biotechnology. Fimbriae is a good candidate for epitope display on the surface of bacteria. The potential of CS3 fimbriae of enterotoxigenic E. coli as a display system has been investigated. A novel cell surface display system with metal binding property was developed by using CS3 fimbriae. Short metal ...
