Lignocellulosic biomass has a recalcitrant structure due to the high crystallinity of cellulose and hydrophobicity of lignin, which is difficult to dissociate due to the interconnection of cellulose within a lignin-hemicellulose matrix (Uma Maheswari et al. [65]; Zoghlami and Paës [74]). Then, the lignin's precipitation could be, with concentrated acid for Table 1 summarized some details as biomass, method, and chemical reagents about combined acid/alkali treatment.

The sequential acid/alkali fiber's pre-treatment is a two-step procedure, in which the first step consists of the acid hydrolysis of biomass to remove hemicellulose fraction and the second step allows the lignin hydrolysis and also produces a solid fraction that's rich in cellulose (Cavali et al. [11]; Das et al. [14]). [Extracted from the article] |
