An animated depiction of the fermentation process, where yeast cells ingest sugars to produce carbon dioxide and ethanol. This process has been employed for thousands of years by humankind to make of beer, wine, bread and several other products. This little guy is hard at work making a beer. Models, textures, lighting, rigging, animation and compositing by John Macfarlane. Model inspired by the yeast strain Saccharomyces cerevisiae, available as a plush toy from GIANTmicrobes.
