摘要	The spent mushroom substrate (SMS) after harvesting mushroom can be regarded as a bio-treated lignocellulose, which offsets the low economic benefit of simple biological pretreatment. In this study, SMS was treated with mechanical pulverization followed by ball milling for enzymatic saccharification. The enzymatic hydrolysis efficiency (EHE) of two-step milled SMS is approximately 103% higher than that of only mechanically pulverized SMS. The smaller initial particle size of SMS could obtain higher EHE in a shorter milling time but not reach the maximum EHE with the increase of milling time. The proper rather than longer time for ball milling is better for improving enzymatic hydrolysis of SMS. SEM and XRD examination reveal that the ball milling pretreatment significantly changes the surface morphologies and reduces the crystallinities of the samples. BET detection indicates that long-time ball milling could decrease the specific surface area of SMS, which might be the reason for the EHE decrease of SMS milled for longer time. The 8-h ball milling made the EHE of SMS increase from 38.75 to 75.71% with the addition of 0.5% (v/v) Tween 80. It provides an environment-friendly pretreatment way without waste liquor generation for improving enzymatic saccharification of lignocellulose.
