A pretreated peel (at a concentration of 20 g/L) in 0.01 M phosphate buffer with pH 6 was used as the SHF medium. The SHF experiments started with the inoculation of pineapple peel with the addition of the enzyme solution (Cellulase, 100 FPU/mL) in 50 mL working volume for 0-96 h. Therefore, a filtersteriled hydrolysate produce from pineapple peel under optimal condition was used as fermentation medium with no nutrient supplementation
