Changes in Gene Expression of Commercial Baker's Yeast during an Air-Drying Process that Simulates Dried Yeast Production

Changes in the gene expression of commercial baker's yeast during an air-drying process, which simulated dried yeast production, were analyzed. K-means clustering suggested that the genes involved in protein folding were transiently up-regulated at early stages, and that the genes involved in fatty acid metabolism were continuously up-regulated.
