Abstract Vetiver grass (VG) high cellulose is an abundant lignocellulosic material used in both cellulolytic enzyme and bioethanol production. Appropriate VG size for fungal growth and enzymes production was 500 µm, while the optimum cellulolytic enzyme production by Aspergillus tubingensis HS1–5 under solid state fermentation using response surface methodology (RSM) was the substrate volume of 12.36 g, moisture content of 56.45% and pH at 4.4.
