摘要

"Yeast strain (gcsi) tolerant to glucose, independent of the carbon source C ~ 2 ~, method for selecting a strain of levedupa (gcsi) tolerant to glucose, independent of the carbon source C ~ 2 ~,Method for producing pyruvic acid and salts of the same, and method for producing lactic acid or salts of the same.Described here are strains of yeasts (gcsi) tolerant to glucose independent of the carbon source C ~ 2 ~, not having detectable amounts of pyruvate decarboxylase activity.Where the strains of yeasts of the wild allele in relation to yeast strain tolerant to glucose independent of the carbon source C ~ 2 ~ are Crabtree positive.They are also described the methods for selecting the strains of yeast tolerant to glucose independent of the carbon source C ~ 2 ~,And the methods to produce acid or salts of the same piru00favido using the yeast strain tolerant to glucose independent of the carbon source C ~ 2 ~.Also, described here, the strains of yeast gcsi having a genome comprising an exogenous lactate dehydrogenase gene.
