	(nmol×108 cells)	(mmol/L)	(nmol×108 cells)	(mmol/L)	(nmol×108 cells)	(mmol/L)	(nmol×108 cells)	(mmol/L)
S. cerevisiae	1.0 (0.05)	0.5	2.4 (0.21)	1.1	100 (4)	46	81 (14)	37
L. kluyveri	2.1 (0.12)	1.0	0.2 (0.03)	0.1	20 (1)	9	98 (8)	45

Concentrations in mmol/L represent the cytosolic pool and were estimated considering a cell volume of 29 μm³ of which 75% of corresponded to cytosol (Kitamoto et al., 1988). Numbers in parentheses are standard deviations.
