Anaerobic fungal growth and sugar degradation is robust against lignin composition with optimal enzyme expression: a relative growth rates of UH3-1 on genetically modified lines of poplar relative to wild-type INRA 717 (64% S-lignin), (p = 0.0317, R2 = 0.1715). b Relative fungal biomass accumulations of UH3-1 on genetically modified lines of poplar relative to wild-type INRA 717 (p = 0.0011, R2 = 0.2991). c Minimum hydrolysis percentages on three of the lines of poplar [17, 19]. d The carbohydrate binding portion of the fungal secretome shows changes in response to S-lignin composition (green arrows)
