Abstract
Six monogenic mutants of K. marxianus, affected in their ability to tolerate ethanol, were assigned to 6 loci etr1 through etr6, probably the hot spots for ethyl methane sulfonate as these loci were found mutated in each of the non-monogenic mutants as well. Differential ethanol tolerance of allelic hexagenic mutants suggests that even more than 6 genes may be involved in controlling ethanol tolerance in K. marxianus.
