A massive screening was performed to identify an acetate-tolerant strain of Saccharomyces cerevisiae. We found that S. cerevisiae ATCC 38555 is acetate-tolerant, with a fermentation profile indicating that it has a high level of acetate adaptation. The global gene expression analysis indicated that AFT1- and HAM-regulated genes are clearly up-regulated. (C) 2012, The Society for Biotechnology, Japan. All rights reserved.
