The increasing demand for renewable energy sources has led to significant interest in second-generation biofuels derived from lignocellulosic biomass and waste materials. This review underscores the pivotal role of valorization meeting global needs, mitigating greenhouse gas emissions, fostering a circular bioeconomy. Key pretreatment methods—including steam explosion, pressure treatment, chemical pretreatment—are analyzed their ability enhance accessibility cellulose hemicellulose enzymatic saccharification. Advances cellulolytic enzyme development fermentation strategies, such as use genetically engineered microorganisms capable fermenting both hexoses pentoses, are discussed detail. Furthermore, potential biorefinery systems is explored, highlighting capacity integrate into biofuel production alongside high-value bioproducts. Case studies recent trends bioethanol biogas examined, providing insights current state research its industrial applications. While hold considerable promise sustainable emissions reduction, challenges related cost optimization, process scalability, technological barriers must be addressed enable large-scale implementation. serves comprehensive foundation bridging gap between laboratory application, emphasizing need continued innovation interdisciplinary collaboration technologies.

In the current study, rice husk ash (RHA) was used as a support in fabrication of heterogeneous catalyst (RHA/CuO/K2CO3) for generating biodiesel from sunflower and castor oil. The value specific surface RHA, CuO, RHA/CuO, RHA/CuO/K2CO3 determined to be 3.63, 54.29, 25.47, 8.17 m2/g, respectively. Based on average roughness (Ra), inclusion CuO RHA structure improved which can improve interaction active phase (K2CO3) with structure. maximum production (99.2%) oil (98.1%) obtained at amount 3 wt%, 'CH3OH: oil' molar ratio 18:1, reaction temperature 65 °C, time 120 min. activation energy transesterification process calculated 52.79 40.09 kJ/mol, Also, ΔH number 50.05 37.35 respectively, shows that is an endothermic process. environmental factor (< 0.5), biocompatibility produced fuel confirmed. It should noted quality according ASTM D6751 EN 14214 standards replace traditional diesel.

Metabolic engineering for high productivity and increased robustness is needed to enable sustainable biomanufacturing of lactic acid from lignocellulosic biomass. Lactic an important commodity chemical used instance as a monomer production polylactic acid, biodegradable polymer. Here, rational model-based optimization was engineer diploid, xylose fermenting Saccharomyces cerevisiae strain produce L-lactic acid. The metabolic flux steered towards through the introduction multiple lactate dehydrogenase encoding genes while deleting ERF2, GPD1, CYB2. A 93 g/L with yield 0.84 g/g achieved using carbon source. To increase utilization reduce acetic synthesis, PHO13 ALD6 were also deleted strain. Finally, CDC19 pyruvate kinase overexpressed, resulting in 0.75 g /g sugars consumed, when substrate synthetic hydrolysate medium, containing hexoses, pentoses inhibitors such acetate furfural. Notably, modeling provided leads understanding influence oxygen production. High xylose, at oxygen-limitation could be explained by reduced oxidative phosphorylation pathway. On contrast, higher levels beneficial likely ATP concentrations are tolerating therein. work highlights potential S. industrial
