Biological pre-treatment systems rely on biological agents (e.g., enzymes) to delignify lignocellulose and make the process of enzymatic hydrolysis more convenient.  The effect of enzymes on the lignocellulosic biomass depends on the type of enzymes as well as the composition of the biomass being treated. This is due to enzyme specificity in terms of the type of the reactions that they catalyze. Laccase (Lac), manganese peroxide (MnP) and versatile peroxide (VP) are enzymes that are used extensively to treat the lignocellulosic substrate<ref>{{Cite journal|author=Baruah J., Nath B.K., Sharma R., Kumar S., Deka R.C., Kalita E.|year=2018|title=Recent Trends in the Pretreatment of Lignocellulosic Biomass for Value-Added Products|journal=Front. Energy Res.|volume=141|page=|doi=10.3389/fenrg.2018.00141}}</ref>. Biological pretreatment of LCB is often knows as a simple, inexpensive, selective, and environmentally-friendly technology. This is mainly due to the fact that biological pretreatment does not require high energy inputs or chemicals addition. Furthermore, enzymatic treatment has found success in the removal of toxic inhibitory compounds (i.e., complete removal of phenolic compounds). The limitations asociated with enzymatic pretreatment is its production cost, stability, shelf life, and reusability<ref name=":0" />.
