The effect of CSLP concentration on LA production via SSCF process from non-detoxified pre-CS. A 10 g/L CSLP. B 15 g/L CSLP. C 20 g/L CSLP. D 25 g/L CSLP. Conditions: 1 L bioreactor containing 500 mL CSLP medium, 20% (w/v) dry CS loading including 9.74 g/L total inhibitors, 35 FPU/g-CS cellulase, 12 h pre-hydrolysis time, 50 °C, pH 5.5
