Basic research is here applied to solve practical problems and to bring the reader up-to-date on recent developments of most aspects of yeast-based industries. Main topics cover: the brewing and distilling industries, wine-making and the nature of winery yeasts, food yeasts, spoilage yeasts, non-saccharomyces yeasts, their substrates and products; the construction of improved industrial yeast strains by site-directed mutagenesis, production of heterologous proteins by genetically-engineered yeasts, and factors affecting yields of such proteins as well as the use of calorimetry in control systems for yeast fermentations. This sourcebook will prove useful to everybody involved in technical applications of yeasts.
