cepas de levedura industrialmente úteis. a invenção se refere a um método para a preparação de cepas da levedura saccharomyces cerevisiae industrialmente úteis e à cepa preparada pelo dito método. em particular, a invenção se refere à criação de cepas mutantes duplas da dita levedura que mostram alta eficiência de conversão de etanol e produção de ácido acético e glicerol substancialmente reduzida durante a produção fermentativa de etanol a partir de uma matéria-prima à base de açúcar. The invention relates to a method for the preparation of industrially useful strains of yeast Saccharomyces cerevisiae and the strain prepared by the method. In particular the invention relates to the creation of double mutant strains of the yeast that shows high ethanol conversion efficiency and substantially reduced acetic acid and glycerol production during fermentative production of ethanol from a sugar-based feedstock.
