Role of cultivation media in the development of yeast strains for large scale industrial use

Abstract

The composition of cultivation media in relation to strain development for industrial application is reviewed. Heterologous protein production and pentose utilization by Saccharomyces cerevisiae are used to illustrate the influence of media composition at different stages of strain construction and strain development. The effects of complex, defined and industrial media are compared. Auxotrophic strains and strain stability are discussed. Media for heterologous protein production and for bulk bio-commodity production are summarized. © 2005 Hahn-Hagerdal et al., licensee BioMed Central Ltd.
