Growth curves and extracellular invertase activity in the wild-type and <i>Xdmig1</i>^<i>-/-</i> strains cultured with glucose or maltose as the sole carbon source.

<p>On the left, data from the wild-type; on the right, data from strain <i>Xdmig1</i>^<i>-/-</i>. Strains were cultured at 22°C in MMv medium supplemented either with A) 2% glucose or B) 2% maltose. Yeast growth (circles) and invertase activity (squares) are represented. Values represent the average of three independent cultures, and error bars correspond to the standard deviation.
