The composition of a synthetic yeast community growing in PDB medium changes over time. The synthetic mixture of six yeasts was grown in PDB for 7 days. Day 0 represents the initial yeast mixture that was used to inoculate the growth medium. The values represent the means of four replicates and standard errors are indicated. One example of at least two experiments is shown. The number of yeast colonies that were counted were 186 (day 0), 103 (day 1), 171 (day 3) and 803 (day 7, the community consisted almost exclusively of Metschnikowia pulcherrima, which could be identified and counted by eye; the total number of colonies that were counted at day 7 was thus higher). Overall,eight yeast colonies could not be identified
