Ultraviolet disinfection is an attractive tool for treating water and eliminating pathogens with safe and available technology especially in developing countries where waterborne diseases cause the death of thousands of people every year. Even though UV is an easy tool to perform disinfection, concerns over the potential of microorganism reactivation constitute an issue for its development. In ...

The carbohydrate content of fruit and vegetable juices has made them a suitable environment for the growth lactic acid bacteria. Various studies have shown that beetroot can be good substrate production probiotic drinks consumers. Therefore, this study was performed to isolate identify bacteria from juice. Beetroot juice prepared two kilograms washed with cold press. Sterile samples were first ...

The aim of the present study was to analyse the type of adhesive factors of selected probiotic strains. A large number of lactic acid bacteria with intestinal and dairy origin were collected and assessed for adhesion on Caco-2 cell line. From the best adherent bacteria, four strains were selected for further research: Lactobacillus gasseri G7, L. plantarum F1, L. helveticus AC and L. delbruecki...

Monoclonal antibodies against a cell wall-associated 45-kDa proteinase from Lactobacillus helveticus CP790 were prepared and used for an immunoblotting analysis of the cell wall extract of CP790. They were found to react with an unidentified 46-kDa protein as well as the 45-kDa proteinase. The 46-kDa protein was copurified with the 45-kDa proteinase by affinity column chromatography using antib...
