Abstract
A method of reducing undesirable microorganism concentration, the method comprises (a) introducing a quantity of fermentable carbohydrate, sugar or cellulose to an aqueous system, (b) introducing a quantity of desirable microorganism to the aqueous system, (c) introducing a hops acid extract into the aqueous system and (d) introducing an organic acid solution into said system.
Claims18
A method of controlling undesirable microorganism concentration in an aqueous solution employed in a fermentation process, the method comprising the steps of:
- (a) introducing a fermentable carbohydrate to the aqueous solution;
- (b) introducing at least one yeast to the solution;
- (c) introducing a hops acid extract into the solution;
- and
- (d) introducing at least one organic acid into the solution;
- wherein the organic acid is selected from the group consisting of citric acid, benzoic acid, propionic acid and their salts.
A method of controlling undesirable microorganism concentration in an aqueous fluid solution employed in a fermentation process, the method comprising the steps of:
- (a) introducing a fermentable carbohydrate to the aqueous system;
- (b) introducing at least one desirable microorganism which is capable of fermenting carbohydrate to the aqueous system;
- (c) introducing at least one hops acid extract into the aqueous system;
- and
- (d) introducing at least one organic acid into the aqueous system;
- wherein the organic acid is selected from the group consisting of citric acid, benzoic acid, propionic acid and their salts.
A method of reducing residual byproduct of antibiotic in a fermentation process, the method comprising the steps of:
- (a) introducing a fermentable carbohydrate to an aqueous system;
- (b) introducing at least one yeast to said system;
- (c) introducing at least one hops acid extract into said system;
- and
- (d) introducing at least one organic acid into said system;
- wherein the organic acid is selected from the group consisting of citric acid, benzoic acid, propionic acid and their salts.
