Fig. 1From: QTL mapping of a Brazilian bioethanol strain links the cell wall protein-encoding gene GAS1 to low pH tolerance in S. cerevisiaePhenotyping of yeast strains in low pH. A Relative growth of 41 industrial, laboratory and wild-type Saccharomyces sp. strains in low pH, represented by the ratio of the colony size at pH 2.5 and neutral (pH 6). The relative growth of JAY270 (PE-2 derived) and CEN.PK122 strains were highlighted in red and blue, respectively. B Spot test of CEN.PK122, JAY270 and other Brazilian bioethanol industrial strains (JP-1, BG and CAT) at pH 2.5 and control (pH 6)Back to article page
