Bioconversion of polystyrene and food waste streams into biochar: An upgraded enzymatic activation system

, 2022
Introduction Pyrolysis is a suitable strategy for managing two residues of global concern: plastics and food waste.1 The addition of plastics to the pyrolysis of biomass (co-pyrolysis) seems to improve the sorptive properties of biochar (carbonaceous pyrolysis product).2 However, one of the technical limitations of this type of co-pyrolysis is the ...

Enzymatic sugar production from elephant grass and reed straw through pretreatments and hydrolysis with addition of thioredoxin-His-S

Biotechnology for Biofuels, 2019
Background The bioconversion of lignocellulose to fermentable C5/C6-saccharides is composed of pretreatment and enzymatic hydrolysis. Lignin, as one of the main components, resists lignocellulose to be bio-digested.

Optimized Enzymatic Bioconversion of Palm Kernel Meal to a Mannose-Rich Syrup

Sustainability
Palm kernel cake (PKC), a byproduct of palm kernel oil extraction, is processed into palm kernel meal (PKM), which contains hemicellulose rich in mannose, a versatile sugar with applications in the pharmaceutical and food industries. However, its association within the lignin–cellulose matrix is a challenge for industrial extraction.
