TL;DR: Application of white-rot fungi capabilities can offer environmentally friendly processes for utilising lignocelluloses over physical or chemical pretreatment, and the effect of biological pretreatment on biomass characteristics, and factors affecting biological pret treatment are reviewed.

TL;DR: The fungal-, phosphoric acid-, and fungal followed by phosphoric Acid pretreatments have improved the digestibility of OPEFB’s cellulose by 4, 6.3, and 7.4 folds, respectively.

TL;DR: The results showed that palmitic and oleic acid with concentrations of 3.0 and 4.5 g/L resulted in >50% inhibition on the biogas production, while stearic acid had an even stronger inhibitory effect and the encased cells in the MBR system were able to perform better in the presence of LCFAs.

TL;DR: The best improvement in biogas production was achieved by a dissolution mode pretreatment of OPEFB, using conditions of 85% NMMO, 3h, and 120 °C, which resulted in 0.408 Nm(3)/kg VS methane yield and 0.032 Nm (3)CH(4/kg VS/day initial methane production rate, which correspond in improving by 48% and 167% compared to the untreated OPE FB, respectively.

TL;DR: Oil Palm Empty Fruit Bunch (OPEFB) was hydrolyzed in a one-stage hydrolysis using dilute-sulfuric acid to produce hydrolyzates for the fermentation process and Hydrolyzate from the first stage was fermented by Mucor indicus while the hydrolyze from the second stage was fermentation by Saccharomyces cerevisiae.
