Abstract
Lignocellulose biomass, as a renewable and biodegradable carbon source, provides <br />
a wide range of valuable bioproducts. Their utilization requires an efficient conversion <br />
process to break down the complex and variable chemical structure of lignocellulose. In <br />
this work, a solid-state fermentation-based pretreatment method for the release of fermentable sugars from corn silage was investigated. The optimal process conditions for <br />
water-soluble sugar extraction were initially explored by response surface methodology <br />
with the aim to achieve the maximum sugar concentration in the extracts. The optimal <br />
extraction conditions were determined: t = 30 min; the liquid-solid ratio L/S = 25 mL g–1; <br />
n = 170 rpm; and T = 30 °C. The changes in the content of water-soluble sugars (glucose, <br />
fructose, sucrose, maltose, maltotriose) were analyzed during seven days of fungal treatment.
