“…Because these materials exist in excess, they represent a potential cheap source of fermentable sugars for bioconversion to ethanol, but cannot be fully exploited because of their recalcitrant nature, which brings with it a concomitant increase in production costs (Zhang and Lynd, ; McCann and Carpita, ; Pauly and Keegstra, ; Vogel, ; Chundawat et al ., ; Álvarez et al ., ). Many laboratories focus their efforts in the manufacture of degradative enzymes of grater and/or longer lasting activity, however, the search for accessory proteins that through non‐enzymatic processes enhance the hydrolytic action of enzymes is another active area towards a more effective saccharification process (Allgaier et al ., ; Smith et al ., ; Ekwe et al ., ; Singhania et al ., ; Koeck et al ., ; Lambertz et al ., ).…”
