Enzymatic saccharification of hot-water pretreated corn fiber for production of monosaccharides

Novel Family of Carbohydrate Esterases, Based on Identification of the Hypocrea jecorina Acetyl Esterase Gene

“…However, genes coding for feruloyl esterases that hydrolyze the ester linkage between the arabinose side group and ferulic acid in arabinoxylan have not been reported. This is in agreement with the fact that no feruloyl esterase activity was detected in culture supernatants of the fungus growing on hemicellulose substrates (9). More recently, the gene product of cip2 (10) was found to code for a glucuronoyl esterase (19) that specifically hydrolyzes methyl-glucuronic acid esters (32).…”

Sugarcane and Woody Biomass Pretreatments for Ethanol Production

“…There have been many studies on the use of LHW for the pretreatment of corn fiber [28,[30][31][32][33], wheat straw [34,35], and sugarcane bagasse [36,37]. Studies on woody biomass from Eucalyptus [38][39][40], and olive tree biomass [41] have also been reported.…”

Extraction of arabinoxylans from wheat bran using hydrothermal processes assisted by heterogeneous catalysts

“…below 100 ºC) is not able to break the cross-links between the WUAXs and the wall matrix (Izydorczyk & Biliaderis, 2007). In order to improve the AXs extraction yield from different biomass, several techniques, such as hydrothermal treatments (Bobleter, 1994;Buranov & Mazza, 2010;Carvalheiro, Garrote, Parajó, Pereira, & Gírio, 2005;Dien et al, 2006;Garrote, Domínguez, & Parajó, 1999;Garrote, Domínguez, & Parajó, 2001;Garrote, Domínguez, & Parajó, 2002;Kim, Hendrickson, Mosier, & Ladisch, 2009;Lavarack, Griffin, & Rodman, 2000;Li, Converse, & Wyman, 2003;Maes & Delcour, 2002;Mok & Antal, 1992;Nabarlatz, Farriol, & Montané, 2004;Negahdar, Delidovich, & Palkovits, 2016;Reisinger et al, 2013;Shen & Wyman, 2011;Tekin et al, 2014), chemical-solvent extractions (Adams et al, 1955;Aguedo, Fougnies, Dermience, & Richel, 2014;Bataillon, Mathaly, Nunes Cardinali, & Duchiron, 1998;Buranov & Mazza, 2010;Choteborská et al, 2004;Doner, Chau, Fishman, & Hicks, 1998;Höije, Gröndahl, TØmmeraas, & Gatenholm, 2005;Hollmann & Lindhauer, 2005;Kim, Kreke, & Ladisch, 2013;Kusema et al, 2011;Lavarack, Griffin, & Rodman, 2002;Maes & Delcour, 2002;Shen & Wyman, 2011;Swennen, Courtin, Lindemans, & Delcour, 2006;Xu et al, 2006;Yao, Nie, Yuan, Wang, & Qin, 2015;…”

“…Hydrothermal treatments are performed in water under relatively high experimental conditions (150-230 ºC) (Garrote et al, 1999). These treatments are green processes and the yields achieved with them are relatively high (58-71%) (Dien et al, 2006;Garrote et al, 2001;Reisinger et al, 2013;Nabarlatz et al, 2004). Chemical methods using bases or acids are not environmentally-friendly and the separation process at the end of the extraction raises sharply the operating costs.…”
