摘要

The invention relates to strains of s.cerevisiae able to secrete beta-galactosidase of heterologous origin to the culture medium as well as to methods for obtaining beta-galactosidase using said strains and methods for the production of glucose/galactose, biomass and bioethanol by cultivating said strains in lactose-rich media. In another aspect, the invention provides methods for the expression of recombinant proteins using a lactose-rich composition as a culture medium for microorganisms producing said protein.
