“…To overcome the obstacle, ultrasound assisted surfactant and enzymatic hydrolysis of Eucalyptus for the production of bio glucose was investigated. Comparing to the experiment done by Elalami et al (2022), the highest glucose yield was 86% obtained by ultrasonication coupled to alkaline pretreatment of bean straw. Cheng et al (2022) demonstrated that surfactant-assisted alkaline pretreatment (SAP) with elevated surfactant concentrations (1% vs. 0.5%) increased sugar yields.…”

Alkaline pretreatment stands out as a valuable strategy in biomass conversion to overcome the recalcitrance of biomass by removing lignin and a part of hemicellulose. This enhances enzyme accessibility and promotes saccharification. However, increasing the alkaline concentration to enhance the delignification and improve glucose yield together presents inherent limitations. In this experiment the amount of delignification and glucose yield resulting from surfactant associated with sonication during mild alkaline pretreatment of Eucalyptus pellita was investigated. Also, the effect of various factors (sonication temperature and surfactant immersion time) on delignification and glucose yield were examined. The results demonstrated that surfactant associated with sonication pretreatment could overcome the limitation of alkaline pretreatment and could increase the amount of delignification alongside enzymatic hydrolysis glucose yield of Eucalyptus pellita wood by around 90%. The findings indicated that surfactant-assisted with sonication during mild alkaline pretreatment of Eucalyptus pellita (i.e., hardwood) could be recommended as a supporting pretreatment method for the production of monomeric sugars.

“…Additionally, lignocellulosic materials can be integrated with the production of other value-added products, such as biofuels or bioplastics. Preprocessing and pretreatment are often required to overcome the recalcitrance of lignocellulosic materials (Elalami et al, 2022). Supply chain logistics and sustainability considerations, including responsible forest management practices, need to be addressed.…”

“…Food waste often contains significant amounts of carbohydrates, including glucose, making it an attractive feedstock option. Food waste and byproducts may require preprocessing, sorting, and potential pretreatment to remove non-biodegradable components and enhance processability (Elalami et al, 2022). The composition of food waste can be diverse and variable, requiring tailored processing approaches.…”

This study explores and optimizes glucose production through various biochemical processes and assesses the potential of diverse feedstock sources to meet the growing demand for renewable carbohydrates. It focuses on glucose production's significance in biological systems and industrial applications, analyzing pathways like enzymatic hydrolysis of polysaccharides and acid hydrolysis of biomass. The kinetics of glucose production are examined, encompassing kinetic models for enzymatic hydrolysis, acid hydrolysis, and fermentation processes. Factors influencing reaction kinetics are explored, and experimental techniques for kinetic parameter estimation are discussed. To address sustainability and resource utilization challenges, the study investigates locally sourced materials like agricultural residues, forest biomass, algal biomass, and food waste as renewable feedstock sources. Optimization strategies for glucose production are presented, using statistical design of experiments and response surface methodology. Techno-economic analysis and life cycle assessments provide a holistic evaluation of environmental and economic aspects associated with glucose production processes. The study's comprehensive approach to glucose production, encompassing both technological advancements and sustainability considerations, offers insights into enzymatic, acid hydrolysis, and fermentation processes, as well as comparing diverse feedstock sources. This knowledge can foster further advancements in the field, benefit industries, and encourage policymakers to promote the integration of renewable carbohydrates in the broader bioeconomy. The research contributes to the global shift towards a greener and more sustainable future, where glucose production plays a key role in building a resilient and eco-conscious society.
