Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>We reported previously the presence of large numbers of gas bubbles inside fermenting brewing yeasts. Here we report that these bubbles deform organelles. The mechanical effects on metabolism and coding functions of yeasts, when organelles including the nucleus are deformed and severely contorted, should now be addressed. The implications of this finding on practical brewing conditions require consideration during optimization of fermentation parameters to prevent CO₂ toxicity effects on fermentation performance and flavour formation.
