FIG. 5.

Hydroxyl radical production by Lac-mycelium from P. eryngii via quinone redox cycling, estimated as 4-hydroxybenzoic acid hydroxylation. The incubation mixtures were as described in the legend to Fig. 3, except 1,10-phenanthroline was replaced by 1 mM 4-hydroxybenzoic acid. The error bars indicate standard deviations.
