Glucose is primarily derived from plant metabolism; it is the primary source of energy for cellular respiration in living organisms. Bioethanol, which is used as fuel, can be obtained from the fermentation of biomass. This article summarizes the current methods of separating glucose and bioethanol. Glucose is generally analyzed by liquid chromatography using a range of sorbents. In the fermentation broth of glucose, the primary produced compound, ethanol, is dissolved in water. Nevertheless, ethanol should be separated to obtain high purity. Distillation is a widely used method and ionic liquids are added to ethanol-water systems to increase separation efficiency. This review discusses the application of new materials (based on silica and membrane) in the separation of ethanol from ethanol-water systems.

Second-generation (2G) bioethanol production, derived from lignocellulosic biomass, has emerged as a sustainable alternative to fossil fuels by addressing growing energy demands and environmental concerns. Fungal sugar transporters (STs) play a critical role in this process, enabling the uptake of monosaccharides such as glucose and xylose, which are released during the enzymatic hydrolysis of biomass. This mini-review explores recent advances in the structural and functional characterization of STs in filamentous fungi and yeasts, highlighting their roles in processes such as cellulase induction, carbon catabolite repression, and sugar signaling pathways.

Cellulase is extensively used in the biorefinery of cellulosic materials to fermentable sugars in bioethanol production. Application of cellulase in the free form has disadvantages in enzyme wastage and low stability. The results of the present work showed these drawbacks can be solved by cellulase immobilization on functionalized FeO magnetic nanoparticles (MNPs) with reactive red 120 (RR120) as the affinity ligands.

Cellulases are an ensemble of enzymes that hydrolyze cellulose chains into fermentable glucose and hence are widely used in bioethanol production. The last enzyme of the cellulose degradation pathway, β-glucosidase, is inhibited by its product, glucose. The product inhibition by glucose hinders cellulose hydrolysis limiting the saccharification during bioethanol production.

Bioethanol represents a clean and renewable alternative to fossil fuels, offering a significant reduction in environmental impact. Second-generation ethanol (2G) is produced using lignocellulosic biomass, which presents additional challenges due to the presence of hemicellulose. The pentose sugars within hemicellulose cannot be efficiently metabolized by conventional yeast strains like Saccharomyces cerevisiae.
