Influence of ammonia and lysine supplementation on yeast growth and fermentation with respect to gluten‐free type brewing using unmalted sorghum grain

Summary Because gluten‐free type brewing with unmalted sorghum does not provide adequate nitrogen for complete fermentation, wort supplementation with ammonia (as diammonium phosphate, DAP ) or lysine on yeast performance was investigated. By Phenotype Microarray, under aerobic conditions, greater yeast growth was indicated with DAP than lysine both as a single source and combined with sorghum wort amino acids. With sorghum fermentation, both...
