  1. aEnzymatic hydrolysis of Avicel was carried out with cellulose concentration of 10 mg/mL and cellulase concentration of 0.3 mg/mL at 50 ºC. Cellulose conversion was determined at 24 h. The concentration of the additives was 2.5 mg/mL
  2. bVanillin concentration was 5 mg/mL
  3. cVanillin concentration was 2.5 mg/mL
  4. dVanillin was pre-incubated 3 h with BSA before enzyme addition
