Original sentence: Even though pretreatment by acid hydrolysis is probably the oldest and most studied pretreatment technique, it produces several potent inhibitors including furfural and hydroxymethyl furfural (HMF) which are by far regarded as the most toxic inhibitors present in lignocellulosic hydrolysate.In fact, Ammonia Fiber Expansion (AFEX) is a promising pretreatment efficiency with no inhibitory effect in resulting hydrolysate
