K. Lewicka et al., GENETIC-VARIABILITY IN THE SACCHAROMYCES SENSU-STRICTO COMPLEX REVEALED BY MULTILOCUS ENZYME ELECTROPHORESIS, International journal of systematic bacteriology, 45(3), 1995, pp. 538-543
Fifty-two strains of the genus Saccharomyces, including 50 yeasts of t
he Saccharomyces sensu stricto complex (sensu Vaughan Martini 1989 [A.
Vaughan Martini, Syst. Appl. Microbiol, 12:119-122, 1989]), were anal
yzed for nine isozyme loci with starch gel electrophoresis. The geneti
c analysis of isozyme data provided further evidence that the Saccharo
myces sensu stricto complex is a genetically heterogeneous group, Twen
ty-two different electrophoretic types were identified and could be gr
ouped into four clusters, However, no correlation between these cluste
rs and the currently defined species Saccharomyces cerevisiae, Sacchar
omyces bayanus, Saccharomyces pastorianus, and Saccharomyces paradoxus
was detected, Several strains could not be assigned to their putative
cluster.
