title: The role of metabolic engineering in the improvement of Saccharomyces cerevisiae: utilization of industrial media.
abstract: Metabolic engineering has become a very important approach to strain improvement in parallel with classical strain development. Although Saccharomyces cerevisiae has been domesticated for ethanol and bread production, there are still some fundamental problems associated with its industrial use. The industrially used carbon sources often consist of a sugar mixture, and due to glucose repression these sugars are utilized sequentially, resulting in prolonged production time. In this article we discuss the application of metabolic engineering for construction of glucose-derepressed strains and specify advantages as well as difficulties associated with this approach.
