*2.1. Materials*

The four GH enzymes [purified Exo-glucanase (Exg-D), MFE-5E, MFE-5H, and MFE-45] used in the current study were derived from hindgut bacterial symbionts of a termite (*T. trinervoides*) metagenome identified and isolated by Rashamuse et al. [20]. The model substrates; carboxymethylcellulose (CMC), Avicel PH101, locust bean gum and the *p*-nitrophenyl (*p*NP) based substrates (*p*NP-α-L-arabinofuranoside (A), *p*NP-β-D-glucopyranoside (G), *p*NP-β-D-mannopyranoside (M), *p*NP-β-D-cellobioside (C) and *p*NP-β-D-xylopyranoside (X)) were purchased from Sigma-Aldrich, South Africa. Beechwood xylan, soluble wheat flour xylan, insoluble wheat flour arabinoxylan and xyloglucan were purchased from Megazyme, Ireland. All chemicals used in this study were of analytical grade and were purchased from Sigma-Aldrich unless stated otherwise.
