Protein supplements production, example plant overview – Pakistan industrial sector update part 9

Baker’s yeast, Saccharomyces Cerevisiae, can grow either aerobically or anaerobically. The energy for growth is obtained from glucose. In the presence of oxygen, baker’s yeast respire glucose into carbon dioxide and water.

Ethanol can also be produced if the concentration of glucose present is too high. Other nutritional requirements for the growth of baker’s yeast are ammonia and phosphorus. (The Yeasts, 1971)

For the production of protein supplements via the growth of baker’s yeast the main source of glucose can be provided by beet and cane molasses. This is mainly because of the high fermentable sugar content inside the molasses. The total sugar content inside
both types of molasses is approximately 50%. These types of molasses also contain various kinds of useful nutrients for the growth of baker’s yeast.

In the design project, both types of molasses are used as the raw materials. Because a mixture of two molasses gives a better result in the industrial production of baker’s yeast than does each separately (The yeasts, 1971). Wort is the term given for a
mixture of beet molasses and cane molasses.

The lower concentration of vitamins namely biotin and thiamine in beet molasses can be covered by cane molasses. The nitrogen concentration in beet is higher in beet molasses than cane molasses.
