Concentrations of metabolites and iron in aspen wood undergoing decay by S. lacrymans

Time (days)	2,5-DMHQ-Ac concna		2,5-DMBQ concna		Oxalate concnb (mM) (soluble)	Iron concnc (mM) (soluble)
	μg g−1 (dry wt) of wood	mM (nominal)	μg g−1 (dry wt) of wood	mM (nominal)
8	2.60 ± 1.43	4.06 ± 2.37	0.46 ± 0.29	0.71 ± 0.47	8.7 ± 3.5	0.46, 0.47

^aValues are from acetylated wood specimens. Average values ± standard deviations (SD) for three replicate wafers are shown. On day 21, 2,5-DMHQ-Ac and 2,5-DMBQ were detected in two out of three replicate wafers analyzed. On day 28, both metabolites were detected in one out of three replicates analyzed (data not shown).

^bAverage values ± SD for three replicate wafers are shown. An average pH value of 4.1 was determined for the extracts after correction for dilution.

^cEight colonized wafers were pooled into two groups of four to obtain duplicate values.

^dND, not determined.
