Abstract

The UV radiation was used in this experiment in order to obtain Saccharomyces cerevisiae strains hearing improved biotechnological properties. Two Saccharomyces cerevisiae mutants were obtained in a suspension containing 1.8x102 cells / cm3, under irradiation for 50 seconds.
The capacity of the Saccharomyces cerevisiae mutants to ferment glucose, galactose, sucrose, maltose and raffinose was tested as well as their capacity to produce ethanol.
The results indicate that only Saccharomyces cerevisiae t1 mutant is capable to ferment all this glucides and it is also able to produce a higher quantity of ethanol than parental strain.
