From: Lignosulfonate and elevated pH can enhance enzymatic saccharification of lignocelluloses
Comparisons of SED of different pretreated solid substrates at two enzymatic saccharification pH with the applications of a SPORL-lodgepole pine hydrolysate (L-BD4-T85-3). (a) SED of SPORL pretreated lodgepole pine (SP-BD4) at 72 h under various L-BD4-T85-3 loadings expressed as concentration of lignosulfonate in the mixed hydrolysate, Celluclase loading: 13 FPU/g glucan; (b) Time-dependent SEDs of SPORL- and dilute acid- pretreated aspen substrates (DA-AS, SP-AS) at a fixed L-BD4-T85-3 loading of 1.0 g/L of lignosulfonate as Klason lignin, Celluclase loading: 7.5 FPU/g glucan.
