HC-assisted pretreatment was statistically optimized and experimentally veriﬁed. High enzymatic digestibility of 97.2% was achieved. The HC increased enzymatic digestibility by 30%. article i nfo abstract Article history: Hydrodynamic cavitation (HC) was employed in order to improve the efﬁciency of alkaline pretreatment Received 27 March 2016 of sugarcane bagasse (SCB).
