Figure 6

The modification of soluble aromatic compounds of SPS caused by laccase-mediator treatment. UV absorbance spectrum (220 to 400 nm) was measured from the liquid fractions of enzymatically hydrolyzed SPS samples treated with laccase and 3 mM mediators. Mediators used were (a) ABTS, (b) AS, (c) TEMPO, and (d) HBT. Dashed line = reference enzymatic hydrolysis (lacking laccase-mediator treatment), dotted line = reference laccase treatment followed by enzymatic hydrolysis (lacking mediator), dash-dotted line = combined curve of reference enzymatic hydrolysis (lacking laccase-mediator treatment) and reference laccase and mediator (lacking SPS), and solid line = laccase-mediator treatment followed by enzymatic hydrolysis.
