TL;DR: Focusing particularly on steam pretreatment, this review examines the influence that pretreatment conditions have on substrate characteristics such as lignin and hemicellulose content, crystallinity, degree of polymerization and specific surface, and the resulting implications for effective hydrolysis by cellulases.

TL;DR: The present study found that SPORL is the most efficient process and produced highest sugar yield, and a post-chemical pretreatment size-reduction approach is proposed to significantly reduce mechanical energy consumption.

TL;DR: Regression models were developed to enable the quantitative prediction of lignin characteristics and antioxidant activity based on the processing conditions and indicated that the lignins with more phenolic hydroxyl groups, less aliphatic hydroxym groups, low molecular weight, and narrow polydispersity showed high antioxidant activity.

TL;DR: In this paper, the Lignol process was used to extract residual lignin from mixed softwood pulp and then used for bio-convincing the cellulose to glucose and subsequent fermentation to ethanol.

TL;DR: Hemicellulose removal was found to be as critical as lignin sulfonation for cellulose conversion in the SPORL process, establishing a novel process using sulfite pretreatment to overcome recalcitrance of lignocellulose (SPORL) for robust and efficient bioconversion of softwoods.
