  • Stimulation of bioprocesses by ultrasound 

    Kwiatkowska, Barbara; Bennett, Jason; Akunna, Joseph C.; Walker, Graeme M.; Bremner, David H. (Elsevier, 2011)
    Ultrasound (US) has become a ubiquitous technological process in a large variety of scientific disciplines. However, little information exists on the use of ultrasound to enhance biological processes and/or processing and ...
  • Synchronization of cell division in the fission yeast schizosaccharomyces pombe by ethylenediaminetetra-acetic acid 

    Ahluwalia, Bhavna; Duffus, John H.; Paterson, Linda J.; Walker, Graeme M. (Society for General Microbiology, 1978)
    When cultures of Schizosaccharomyces pombe growing exponentially in a minimal medium were treated with 50 mM-EDTA for 1 h, nucleic acid synthesis was inhibited but protein synthesis was not. On transfer to fresh medium, ...
  • Synchronization of yeast cell populations 

    Walker, Graeme M. (Springer Verlag, 1999-06)
    The study of synchronous populations of yeast cells has provided a wealth of information into regulatory aspects of the eukaryotic cell division cycle. Synchronized yeast cultures may also have potential benefit when ...
  • Thermotolerance in Saccharomyces cerevisiae is linked to resistance to anhydrobiosis 

    Rapoport, Alexander; Rusakova, Anna; Khroustalyova, Galina; Walker, Graeme M. (Elsevier, 2014-11)
    We have demonstrated that a thermotolerant yeast strain (Saccharomyces cerevisiae TS1) is much more resistant to dehydration–rehydration treatments than a mesophilic strain of S. cerevisiae. Yeast resistance to ...
  • Use of response surfaces to investigate metal ion interactions in yeast fermentations. 

    Chandrasena, Gamarallage; Walker, Graeme M.; Staines, Harry J. (American Society of Brewing Chemists, 1997)
    The metal cations K(^+), Mg(^2+), Ca(^2+), and Zn(^2+) are known to directly influence fermentative metabolism in yeast, and therefore knowledge of their interactions is essential to manipulate their availability in ...
  • The use of sorghum as a renewable energy biomass source 

    Deeni, Yusuf Y.; Nasidi, Muhammad; Walker, Graeme M. (Elsevier, 2011-09)
  • Williopsis saturnus yeast killer toxin does not kill Streptococcus pneumoniae 

    Ochigava, Irma; Collier, Phillip J.; Walker, Graeme M.; Hakenbeck, Regine (Springer Verlag, 2011-03)
    Streptococcus pneumoniae is an important human bacterial pathogen, and the increase in antibiotic resistance demands the development of new antimicrobial compounds. Several reports have suggested that yeast killer toxins ...
  • Wines: microbiology of winemaking 

    Walker, Graeme M. (Academic Press, 2014)
    This chapter provides a concise overview of the microbiology of winemaking, with particular focus on the role of yeasts in grape must fermentations. There is also coverage of the roles of bacteria, both good and bad, with ...
  • Yeast vitality and stress responses - novel investigative approaches 

    Walker, Graeme M. (The American Society of Brewing Chemists, 2012)
  • Yeasts 

    Walker, Graeme M. (Elsevier/Academic Press, 2009-07)
    Yeasts are eukaryotic unicellular microfungi that are widely distributed in the natural environment. Around 1000 yeast species are known, but this represents only a fraction of yeast biodiversity on Earth. The fermentative ...
  • Yeasts 

    Walker, Graeme M. (Elsevier Inc., 2009-02)
    Yeasts are eukaryotic unicellular microfungi that are widely distributed in the natural environment. Around 1000 yeast species are known, but this represents only a fraction of yeast biodiversity on Earth. The fermentative ...
  • Yeasts 

    Walker, Graeme M. (Academic Press, 2011)
    Yeasts are eukaryotic unicellular microfungi that are widely distributed in the natural environment. Around 1500 yeast species have been characterised, but this represents only a fraction (<1%) of yeast biodiversity on ...
  • 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 ...
