Detailed explanation-1: -Cheese and wine, made by fermentation, are early examples of biotechnology.
Detailed explanation-2: -The yeast Saccharomyces cerevisiae is one of the oldest and most frequently used microorganisms in biotechnology with successful applications in the production of both bulk and fine chemicals.
Detailed explanation-3: -Microbial fermentation is used commercially by certain industries. Lactic acid fermentation by certain fungi and bacteria, for instance, is used by the dairy industry to make yogurt and cheese. Alcohol fermentation by yeasts is used in making wine and liquor.
Detailed explanation-4: -We see three major fields of application for yeasts in modern biotechnology: production of metabolites, production of recombinant proteins, and in vivo biotransformations. Traditionally “yeast” denotes Saccharomyces cerevisiae and its close relatives, used for alcoholic fermentation and baking.
Detailed explanation-5: -Fermentation processes to produce wines, beers and ciders are traditionally carried out with Saccharomyces cerevisiae strains, the most common and commercially available yeast.
