Ensuring the economic viability of cellulosic ethanol relies heavily on pretreating lignocellulosic biomass to enhance subsequent enzymatic hydrolysis and fermentation processes. However, finding the optimal technology for every feedstock remains a challenge. Diverse Pretreatment Methods: Balancing Pros and Cons Various pretreatment methods, each with distinct advantages and disadvantages, are continuously developed to maximize cellulose accessibility, […]
The initial step in breaking down lignocellulose typically involves traditional pretreatment methods, which can be physical, chemical, a combination of both (physicochemical), or biological. Physical Pretreatments Physical pretreatments aim to enhance the surface area and biomass pore size without involving chemical agents. Methods include mechanical comminution (size reduction), irradiation, and extrusion. While these methods alone […]
