In general acids are better disinfectants than alkalis. Mode of action is attributed to an increase of H + and OH – species in solutions which interfere with certain microbial functions, however the total effect is not only dependent on pH alone. Weak organic acids are more potent than inorganic acids despite low dissociation rates in solution.

Lignocellulosic biomass can be treated with chemical solutions such as acid and alkali during the extrusion process [33,34,35]; however, the acid would cause corrosion problems due to the construction material of the extruder, thus, acid resistant stainless steel alloys such as AL6XN, would be required for extruder screws and barrel fabrication
Furthermore, woody biomass is generally more resistant to degradation than other types of lignocellulose. Softwood is typically more difficult to hydrolyze than hardwood or agricultural residues [8-12]. Hydrolysis of cellulose can be catalyzed by using strong inorganic acids or hydrolytic enzymes, including cellulases [13,14]. Acid hydrolysis
