Abstract

Lignocellulosic Biomass represents one of the most abundant and sustainable carbon sources available on Earth. The abundance of lignocellulose biomass such as oil palm empty fruit bunch (OPEFB) waste can be a big problem for the environment. Lignocellulose is a complex structure consisting of a robust lignin and hemicellulose matrix that surrounds cellulose molecules. The remaining portion of lignocellulosic biomass comprises extractives such as oils, ash, and proteins. Lignocellulosic materials possess significant biotechnological value due to the chemical properties of their constituents. These lignocellulosic resources are rich in energy compounds and can serve as raw materials across various industries. Bioconversion processes targeting specific components within lignocellulosic waste have been employed in biorefining to generate a wide array of bio-based products. Sugar fermentation transforms lignocellulosic constituents into biofuels and various bioproducts. Sugar fermentation transforms lignocellulosic constituents into biofuels and various bioproducts. Conversely, syngas or thermochemical conversion processes convert biomass into valuable substrates for subsequent fermentation processes. This diverse array of bioconversion techniques yields products that include organic acids, biopolymers, proteins, biofertilizers, composites, industrial enzymes, and biofuels. Effectively initial processes which is pretreatment and hydrolysis of OPEFB plays an essential role for bioconversion process.
