Abstract
Provided are aqueous fermentation feedstocks comprising glucose monomers at a concentration of less than 50 gram/Liter (g/L) of the total feedstock, water-soluble dextrose oligomers at a concentration in a range between 50 g/L and 300 g/L of the total feedstock; and water. Further provided are methods of production thereof and uses thereof in the production of single cell protein and/or ethanol.
Claims12
A method for producing an aqueous fermentation feedstock comprising glucose monomers at a concentration of less than 50 gram/Liter (g/L) of the total feedstock;
- water-soluble dextrose oligomers at a concentration in a range between 50 gram/Liter and 300 gram/Liter of the total feedstock;
- and water, for growth of single cell proteins, the method comprising
- (i) providing a starchy grain;
- (ii) comminuting said starchy grain to form comminuted starchy grain;
- (iii) adding water to said comminuted starchy grain to form an aqueous slurry of said comminuted starchy grain;
- (iv)hydrolytically treating said aqueous slurry at a temperature greater than 25 degrees Celsius to form a starchy mash comprising said water soluble dextrose oligomers, said glucose monomers and water-insoluble carbohydrates;
- and
- (v) filtering at least a fraction of said starchy mash through a hydrophobic microfiltration membrane selected from the group consisting of a sintered stainless steel membrane and a polymeric membrane to form an aqueous filtration permeate consisting of said aqueous fermentation feedstock, and a filtration retentate comprising said water-insoluble carbohydrates.
