Temporal variations in the content of (a) guaiacyl monolignol (G-lignin), (b) syringyl monolignol (S-lignin), and (c) the sum of the two monolignols (G&S-lignin) in the degradation residues during the 15-day experiments, with measurements at 2-day intervals. Experiments: Con., uninoculated control; PM, Pseudomonas mandelii; AF, Aspergillus fumigatus; PM + AF, co-culture of the two microbes. Bars on a given date labelled with different letters differ significantly (P < 0.05) between the four treatments.
