Yeast biomass is an excellent source of proteins, nucleic acids, and vitamins. It has been produced and consumed in baked goods and other foods for thousands of years and offers significant advantages when compared to other potential new microbial protein sources. Use of Yeast Biomass in Food Production provides up-to-date information regarding the chemical composition and biochemistry of yeasts, discusses the biotechnological basis of yeast production and possibilities for influencing yeast biomass composition using new techniques in molecular biology. The book examines techniques for producing yeast protein concentrates (and isolates) while still retaining their functional properties and nutritive values, as well as the various uses for these materials and their derivatives in different branches of the food industry. Finally, the book explores possibilities for the production and industrial use of other yeast components, such as nucleic acids, nucleotides, cell wall polysaccharides, autolysates, and extracts. Food microbiologists and technologists, as well as biotechnologists, will discover that this book is an invaluable reference resource.

As the number of dairy farms is increasing, it is obvious that the discharge of whey from them can affect the environment. In other hands with this current population explosion and the limited land resources, the world will be soon unable to feed its population. That means protein gap also would continue to increase unless well planned measures are adopted to handle the situation. It is therefore, important to increase protein production by utilizing all the available ways and means. In order to bridge this gap, Single Cell Protein production is an innovative and an alternative way. Thus, this microbial biomass production and bioconversion of the wastes through microbial degradation and is the natural way to recover resources. As far as Single Cell Protein production is concerned, yeasts are probably the most widely accepted. Therefore this work delivers the information about yeast species which can be found in dairy products, their potential in converting substrate lactose to Single Cell Protein and their identification system. Therefore the researchers who have an interest in this area, the food processing industries and the environmentalists can be benefited from this work.
