The present disclosure provides yeast transformed with a nucleic acid molecule (GAT1 ) to reduce nitrogen catabolite repression of asparagine transport/degradation and/or overexpress genes (ASP1 or ASP3) encoding cell- wall or extracellular proteins involved in asparagine degradation and/or genes (AGP1 or GNP1 or GAP1 ) encoding proteins involved in asparagine transport under food preparation/processing conditions. The genetically modified yeast has enhanced ability to reduce acnlamide concentration in foods prepared by heating. Also provided are methods and uses of the transgenic yeast for reducing acnlamide in a food product and food products having reduced acrylamide content prepared using the transgenic yeast.La presente revelación proporciona microorganismos transformados con una molécula de ácido nucleico para reducir la represión catabólica por nitrógeno del transporte/degradación de la asparagina y/o sobreexpresar genes que codifican proteínas extracelulares o de pared celular involucradas en la degradación de la asparagina y/o genes que codifican proteínas involucradas en el transporte de asparagina en condiciones preparación/procesamiento de alimentos. También se proporcionan métodos y usos de los microorganismos y productos alimenticios preparados con dichos microorganismos.
