Total proteins released in the culture medium. Total proteins released in the culture medium of batch cultures of the indicated wild type and Δgas 1 strains of S. cerevisiae and Z. bailii. Yeasts were grown in shake flasks in minimal YNB-based medium with 5% glucose. Cells were inoculated at 0.1 OD and harvested after 72 hours of cultivation. Amount of released proteins (in mg l-1 of culture broth) were normalized for OD values.
