<p>Processes for the conversion of starch and protein containing cellulosic substances such as cereals, bran from cereal and flour mills and broken pieces and crumbs of essentially fat-free baked goods from bakeries into nutriments richer in proteins by dispersing in water the cellulosic substances containing starches and proteins in comminuted form, subjecting the resulting slurry of the cellulosic substance in water to hydrolysis to convert the starches therein to glucose or other fermentable sugars, separating the glucose-containing liquid from the remaining solids by ultrafiltration, aerobically cultivating in the said glucose-containing liquid a yeast such as Candida utilis or a bacterium that ferments and utilizes glucose for growth and subsequently recovering from the fermented liquid the protein-containing yeast or bacterium that was grown therein for use as a protein concentrate in human nutrition or as a supplement for animal feeds.</p> |
