The utilization of lignocellulosic materials to produce a variety of building blocks (e.g. fermentable sugars) is an interesting alternative approach to meeting the growing demand for high value chemicals. Cellulose and hemicellulose can be hydrolyzed by cellulase and xylanase enzymes into their respective building blocks (hexoses and pentoses), which can later be converted into the targeted compounds. The aim of this study was to test the ability of Paenibacillus illinoisensis CX11 to saccharify different lignocellulosic materials, and to determine its ability to produce cellulolytic and xylanolytic enzymes for possible use in converting lignocellulosic materials into their respective fermentable sugars. The ability of P. illinoisensis CX11 to produce CMCase, xylanase, FPase, and avicelase was tested using SSF of corn stalk. Furthermore, the ability of P. illinoisensis CX11 to saccharify lignocellulosic materials was tested using corn stalk, wheat bran, sawdust, and corn cob. The amount of reducing sugars released from the saccharification of lignocellulosic materials was determined by the 3,5-dinitro-salicylic acid (DNS) method. Obtained results showed that P. illinoisensis CX11 can produce CMCase (400.12 ± 1.23 U/L), xylanase (385.57 ± 2.25 U/L), FPase (266.93 ± 2.22 U/L), avicelase (187.85 ± 2.22 U/L) and extracellular protein (4.56 ± 0.14 mg/L). Moreover, P. illinoisensis CX11 showed an ability to saccharify lignocellulosic materials. These findings confirm that P. illinoisensis CX11 has the ability to produce cellulolytic and xylanolytic enzymes, and to hydrolyze different lignocellulosic materials into fermentable sugars. Therefore, this study concludes that P. illinoisensis CX11 can be considered a good source of cellulase and xylanase enzymes to saccharify different lignocellulosic materials.
