Effect of Microwave Pretreatment on Sugar Recovery from Corn Stover

Microwave steam explosion and enzymatic hydrolysis of vine-branch

“…Various methods have been worked out for the digestion of cellulose (LEMMER et al, 2017), among them: hydrolysis with weak or strong acids (SUN & CHENG, 2005), with alkalis (HU & WEN, 2008); with wet oxidation (SCHMIDT & THOMSEN, 1998;PALONEN et al, 2004), pre-treatment with steam (VIOLA et al, 2008); enzymatic hydrolysis (DUFF & MURRAY, 1996), and various combinations of all the above (FENG et al, 2012(FENG et al, , 2013. There are numerous studies dealing with microwave (MW) pre-treatment of cellulose-based biomass such as corn-stalk (DONEPUDI & MUTHUKUMARAPPAN, 2009), wheat-straw (SAHA et al, 2008), ricestraw (ZHU et al, 2005), soy-husk (KARUPPUCHAMY & MUTHUKUMARAPPAN, 2009), rice-husk (ZHAO et al, 2010), and panic-grass (HU & WEN, 2008;KESHWANI et al, 2007). SE, one of the most frequently used methods of pre-treatment (MCMILLAN, 1994), has proved to be an effective, quick, and cheap way of pre-treatment for enzymatic hydrolysis (JØRGENSEN et al, 2007;GNANSOUNOU, 2010).…”
