^aSaueda fruticosa (SF) saccharified with either crude xylanase (SF-crude) or purified xylanase (SF-purified) and Ipomea pes-caprae (IPC) either saccharified with crude xylanase (IPC-crude) or purified xylanase (IPC-xylanase). The results were compared with the substrate without enzymatic saccharification
*Insignificant standard deviation
