Abstract
The alleviation of glucose control of maltose metabolism brought about by MIG1 disruption was compared to that by MAL overexpression in a haploid Saccharomyces cerevisiae strain. The sugar consumption profiles during cultivation of the wild type, single transformants and a double transformant in a mixed glucose-maltose medium revealed that the MAL-constitutive strains were more alleviated than the single MIG1-disrupted transformant. While all transformants exhibited higher maximum specific growth rates (0.24-0.25 h(-1)) in glucose-maltose mixtures than the wild type strain (0.20 h(-1)), the MAL-constitutive transformants grew even faster (0.27-0.30 h(-1)) in pure glucose medium than the wild type strain (0.24 h(-1)).
