Relative activity of Lfa2 in different concentrations of lignocellulose pretreatment-derived compounds. Different concentrations of furfural (0–1%), 5-hydroxymethyl furfural (5-HMF) (0–1%), vanillin (0–2%), and 4-hydroxybenzoic acid (4-HBA) (0–2%) on Lfa2 activity were analyzed using 4 mM pNPβGlu as substrate in citric acid-phosphate buffer 50 mM pH 5.5 at 50°C. Control experiments were performed in absence of lignocellulose pretreatment-derived compounds. All measurements were done in triplicates. Error bars show SD. Activity at 100% refers to a specific activity of 7.9 μmol min-1 mg-1.
