The theoretical journey from cellulose to glucose, a crucial step in ethanol production, is a nuanced process influenced by various factors. The envisioned ethanol yields from different lignocellulosic sources, as researched by Sassner and team in 2008, present promising possibilities yet are hampered by practical inefficiencies. Theoretical ethanol yields, measured in liters per dry metric […]
Within the intricate web of enzymatic processes, pectinases emerge as key players in the degradation of pectic compounds, notably pectin. This comprehensive exploration aims to unravel the complexities surrounding pectin-degrading enzymes, shedding light on their classifications, mechanisms, and the diverse array of enzymes within this category (Sharma et al., 2013a). Main Pectinases: Guardians of Pectin […]
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 […]
