C andida albicans is a commensal organism; however, it causes fatal diseases if the host immunity is compromised. The mortality rate is very high due to the lack of effective treatment, leading to ceaseless demand for novel pharmaceuticals. In this study, time‐course proteomics of C . albicans during adaptation to fetal bovine serum ( FBS ) was described. Time‐course proteomics is a promising way to understand the exact process of going adaptation in dynamically changing environments. C andida albicans was cultivated in yeast nitrogen base ( YNB ) ± FBS media, and we identified 1418 proteins in the endpoint samples incubated for 0 or 60 min by a LC ‐ MS / MS system with a long monolithic silica capillary column. Next, we carried out time‐course proteomics of the YNB + FBS samples to identify top‐priority proteins for adaption to FBS . We identified 16 proteins as nascent/newly synthesized proteins, and they were recognized as candidates of important virulent factors. Gene ontology analysis revealed that transport‐related proteins were enriched in the 16 proteins, indicating that C . albicans probably put priority in time on the acquisition of essential elements. Time‐course proteomics of C . albicans revealed the order of priority to adapt to FBS . Depicting time‐course dynamics will lead to profound understandings of virulence of C . albicans .
