  • Accumulation and cellular distribution of zinc by brewing yeast 

    De Nicola, Raffaele; Walker, Graeme M. (Elsevier, 2009-04)
    This study focused on the interactions between yeast and zinc in relation to beer fermentations. Yeast accumulation of zinc from growth media, including malt wort, was found to be rapid following inoculation with a brewing ...
  • Influence of zinc on distiller’s yeast : cellular accumulation of zinc and impact on spirit congeners 

    De Nicola, Raffaele; Hall, Nichola; Melville, Stuart G.; Walker, Graeme M. (Institute & Guild of Brewing, 2009)
    Accumulation of zinc by a whisky distilling yeast strain of Saccharomyces cerevisiae was studied during fermentation of malt wort and synthetic defined medium. Zinc uptake by yeast cells was very rapid in malt wort, as ...
  • Interactions between yeasts and zinc 

    De Nicola, Raffaele; Walker, Graeme M. (Springer Netherlands, 2009-04)
    Zinc is an essential trace element in biological systems. For example, it acts as a cellular membrane stabiliser, plays a critical role in gene expression and genome modification and activates nearly 300 enzymes, including ...
  • Physiological and transcriptional responses of Saccharomyces cerevisiae to zinc limitation in chemostat cultures 

    Nicola, Raffaele De; Hazelwood, Lucie A.; Hulster, Erik A. F. De; Walsh, Michael C.; Knijnenburg, Theo A.; Reinders, Marcel J. T.; Walker, Graeme M.; Pronk, Jack T.; Daran, Jean-Marc; Daran-Lapujade, Pascale (American Society for Microbiology, 2007-12)
    Transcriptional responses of the yeast Saccharomyces cerevisiae to Zn availability were investigated at a fixed specific growth rate under limiting and abundant Zn concentrations in chemostat culture. To investigate the ...
  • A review of vehicle related metals and polycyclic aromatic hydrocarbons in the UK environment 

    Napier, Fiona; D'Arcy, Brian; Jefferies, Christopher (Elsevier, 2008-06)
    This paper considers the importance of automobiles as a continuing source of persistent pollutants in the environment, using the UK as a case study. The mass of lead, copper, zinc and polycyclic aromatic hydrocarbons (PAHs) ...
  • Zinc accumulation and utilisation by wine yeasts 

    De Nicola, Raffaele; Hall, Nichola; Bollag, Tatiana; Thermogiannis, Georgios; Walker, Graeme M. (Dove Medical Press, 2009-02)
    The present study has focused on the accumulation of zinc by wine yeast strains of Saccharomyces cerevisiae during fermentation of both grape juice and chemically defined medium with different carbohydrates and at varying ...
  • Zinc interactions with brewing yeast: impact on fermentation performance 

    De Nicola, Raffaele; Walker, Graeme M. (American Society of Brewing Chemists, 2011)
    The effect of zinc on brewing yeast cells was studied in relation to zinc uptake, fermentation performance and flavour congener formation. Experiments using malt wort with variable supplements of zinc salts were conducted ...
