Effect of a solid loading b incubation time c temperature d pH e enzyme concentration on percentage delignification and residual lignin. Raw pineapple leaf waste powder is the substrate and effect of various parameters like solid loading (5–40% w/v), incubation time (2–12 h), temperature (30–60 °C), pH (3–10) and enzyme concentration (100–1000 IU/mL) on enzymatic delignification process of the substrate has been studied
