Oil palm empty fruit bunches (EFB) were subjected to microbial pre-treatment of lignocellulosic biomass bioconversion to fermentable sugar. Microbial pre-treatment was carried out by inoculating Ganoderma boninense spores through solid state fermentation. The samples were initially treated with Sulphuric acid method prior to reading with UV-Visible Spectrometer. The readings were taken before and after inoculation of EFB with G. boninense. Bioconversion of 20 g EFB via solid state fermentation was done in five different amounts of G. boninense spore namely 0.0 g (control), 0.5 g (T2), 0.7 g (T3), 0.9 g (T4) and 1.1 g (T5) in 7 days. The result shows the highest delignification in sample inoculated with 1.1g of G. boninense spores, in which the spores are successfully reduced by 61.97% of lignin from total EFB biomass in 7 days compared to 60.08% (T4), 58.65% (T3) and 54.85% (T2). Meanwhile, for control the lignin content was reduced by 5.07% in 7 days. The study shows that G. boninense has the ability to remove lignin from EFB whereby longer incubation period and higher number of spores contribute to higher delignification percentage.
