  1. Cell surface shaving of C. parapsilosis cultures with trypsin and additional digestion of the obtained proteins for 24 h was performed. The resulting peptides were then analyzed using the Dionex Ultimate 3000 UHPLC system coupled to an HCTUltra ETDII mass spectrometer. The obtained lists of peaks were searched against the NCBI protein database using an in-house Mascot server. The normalized abundance factors (NSAFs) were calculated for each of the tested growth conditions and the statistical significance with respect to the defined synthetic medium is indicated as follows: **p from 0.001 to 0.01, ***p from 0.0001 to 0.001; and ns, not significant by Student t-test. The arrows indicate that the protein was only identified from cultures grown in AS, VS, AU or AN and not in the synthetic medium
