C. Compagno et al., FERMENTATION OF WHEY AND STARCH BY TRANSFORMED SACCHAROMYCES-CEREVISIAE CELLS, Applied microbiology and biotechnology, 43(5), 1995, pp. 822-825
Among the main agro-industrial wastes, whey and starch are of prime im
portance. In previous work we showed that strains of Saccharomyces cer
evisiae transformed with the episomal plasmid pM1 allow production of
yeast biomass and ethanol from whey/lactose. Ethanol production from w
hey and derivatives has been improved in computer-controlled bioreacto
rs, while fermentation studies showed that the composition of the medi
um greatly modulates the productivity (g ethanol produced/l in 1 h of
fermentation). A yeast strain for the simultaneous utilization of lact
ose and starch has also been developed. Biotechnological perspectives
are discussed.
