Mean count of yeast cells displaying vacuole damages from a single large to numerous small sized vacuoles caused by furfural treatment.

	2-4/Medium	8.5 ± 1	22 ± 4	35.5 ± 4
	> 4/Small	5.0 ± 5	30 ± 12	34.5 ± 6
24	Single/large	77 ± 13	36 ± 16	7.5 ± 8
	2-4/Medium	16 ± 6	21 ± 0.2	18.0 ± 13
	> 4/Small	7 ± 8	43 ± 16	74.5 ± 21

Prior to adding furfural, 96%, 2% and 2% of cells contained large, medium and small shaped vacuoles, respectively. Data represent averages of two experiments with standard error indicated. At least 100 cells were examined at each time point.
