**5. Conclusion**

Lignocellulosic material, especially from oil palm biomass, is a promising source as a feedstock for the fermentation process as it has a high content of cellulose and hemicellulose. Substrate selection is the most important factor in determining the techno-economic viability of large-scale chemical products. The substrate should be on the basis of easy availability, conversion efficiency, being toxic-free and low operational cost. Thus, the bioconversion route in chemical product production may create business opportunities to utilize the abundant agro-industrial waste that is being generated, particularly in terms of environmental pollution.
