Commercial Production
Nutritional yeast is produced by culturing a yeast in a nutrient medium for several days. The primary ingredient in the growth medium is glucose, often from either sugarcane or beet molasses. When the yeast is ready, it is killed (deactivated) with heat and then harvested, washed, dried and packaged. The species of yeast used is often a strain of Saccharomyces cerevisiae. The strains are cultured and selected for desirable characteristics, and often exhibit a different phenotype from strains of S. cerevisiae used in baking and brewing.

Famous quotes containing the words commercial and/or production:
“The commercial class has always mistrusted verbal brilliancy and wit, deeming such qualities, perhaps with some justice, frivolous and unprofitable.”
—Dorothy Nevill (1826–1913)
“It is part of the educator’s responsibility to see equally to two things: First, that the problem grows out of the conditions of the experience being had in the present, and that it is within the range of the capacity of students; and, secondly, that it is such that it arouses in the learner an active quest for information and for production of new ideas. The new facts and new ideas thus obtained become the ground for further experiences in which new problems are presented.”
—John Dewey (1859–1952)
