Techniques for the identification of the spoilage yeasts Saccharomyces cerevisiae and members of the Zygosaccharomyces genus from food and beverages sources were evaluated. The use of identification systems based on physiological characteristics resulted often in incomplete identification or misidentification. Also the cellular fatty acid...

It is well known that immune reactivity declines with age. Recently, we demonstrated that the age-related decrease in IL-2 production by CD4+ T cells was accompanied by an increased production of IL-4 and interferon-gamma (IFN-gamma). This age-related shift in the profile of lymphokine production was related to phenotypic changes within the CD4+...

Vleeswaren, die in de verpakking worden verhit, zijn veel langer houdbaar dan vergelijkbare produkten, die na de verhitting worden verpakt. De verpakking beschermt de produkten namelijk tegen bacteriologische herbesmetting na de verhitting. De verhitting van produkten in de verpakking kan bestaan uit: - een pasteurisatie: inactivering van...

Samples of barley, wheat and maize were analysed for deoxynivalenol (DON). Samples were extracted with aqueous chloroform-ethanol. The extract was purified by column chromatography on silica gel. DON was derivatised with heptafluorobutyric (HFB) acid anhydride. The glassware was silylated to prevent deterioration of the HFB derivative, which...

In seven member countries of the European Communities, three abattoirs were visited on three occasions in each of two surveys and at each visit ten beef carcasses were sampled, before chilling, at defined sites on the neck, brisket, forerib and medially on the round. In Survey I, samples were plated for total viable count (TVC) at 30?? (ISO 2293...

A modified microbiological safety cabinet which can be used as a class II and a class III safety cabinet has been bacteriologically tested. This cabinet makes use of a high-speed down-flow air curtain in the front opening to minimize the amount of air escaping over the arms of the operator. By using artificial aerosols and a dummy or a test...

The effects of ozone and ozonized olefins on aerosol survival of bacteriophage phiX174 were studied. The ozone concentrations used were between 0 and 110 parts/109, giving decay rates up to 0.03 min-1. The olefins used were trans 2 butene and cyclohexene in concentrations of 500 parts/109 and 2.4 parts/106, respectively. Olefins alone have no...

Using the microthread technique the survival of Escherichia coli MRE 162 in open air was measured in different parts of The Netherlands. The presence of bactericidal compounds (open air factor=OAF) could be demonstrated on several days and quantitated in relative units of OAF concentration. In the absence of ozone the OAF concentration was...
