Relative intensity of molar mass (g/mol) distribution of soluble and insoluble DAP-SSF residues from gel permeation chromatography. Distribution of a pine residue at 0 and 96 h of DSM 1069 fermentation, b poplar residue at 0 and 96 h of DSM 1069 fermentation, c switchgrass residue at 0 and 96 h of DSM 1069 fermentation, d pine residue at 0 and 96 h of PD630 fermentation, e poplar residue at 0 and 96 h of PD630 fermentation, and f switchgrass residue at 0 and 96 h of PD630 fermentation. The solid red and dashed magenta lines refer to the soluble fraction at 0 and 96 h of fermentation, respectively, and the solid blue and dashed cyan lines refer to the insoluble fraction at 0 and 96 h of fermentation, respectively
