Biomass wastes from oil palm production have the potential to be converted into high value
bioproducts. Oil palm biomass (OPB) includes empty fruit bunch, mesocarp fibre, palm shell
kernel, oil palm fronds and trunks. The production of microbial oils from OPB can be
achieved through biochemical routes comprising pretreatment and enzymatic hydrolysis of
OPB to produce fermentable sugars (OPB hydrolysates), followed by the cultivation of
oleaginous microorganism on OPB hydrolysates. This paper reviews the methods and …
