Fitness of natural Saccharomyces cerevisiae strains [Expression]

To characterize the ecological interactions among S. cerevisiae strains coming from the same geographical area, we examined the fitness of two natural isolates from San Giovese grapes, alone or in competition, in synthetic wine must (SWM)为表征来自同一地理区域的酿酒酵母（Saccharomyces cerevisiae）菌株间的生态互作关系，我们针对两株分离自圣焦韦塞葡萄的天然分离株，在合成葡萄酒醪（SWM）中分别开展单独培养与竞争性共培养实验，测定其适合度。
