In the production of Scotch whisky many factors are known to influence the final quality, including water, barley type, extent of peating and storage conditions. The most important contributor, however, is undoubtedly the oak cask in which maturation

Increased confidence in conductimetric detection of salmonellas was achieved by combining a bacteriophage-based test with use of a selenite cystine trimethylamine oxide dulcitol medium and a modified lysine decarboxylase broth. All 81 Salmonella isol
