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.

Abstract Cow urine (CU) – a natural bio-organic waste product with immense medicinal value has been traditionally used by human beings for centuries. Researchers have reported the multi-purpose usage of CU in various sectors such as agriculture, medical, emulsified diesel fuel, and electricity generation. The beneficial effect is mainly attributed to its composition which depends on multiple factors dietary habit, demography, breed type etc. consists many useful elements enzymes are essential maintaining ecological balance well-being society. In spite limited benefits, there still lack knowledge scientific CU. this investigation, antioxidant, scavenging activity, reducing power assay from adult, pregnant, lactating cow calf assessed. quantity bio-chemical constituents cow, varied significantly. concentration urea, urea nitrogen, uric acid, calcium creatinine was high pregnant raw sample. Whereas, amount sodium chlorine were Total phenol found be adult sample, followed samples, responsible antimicrobial activity. Results show highest potent antioxidant activity inhibition DPPH, superoxide anion, nitric oxide, hydroxyl free radicals, better ability sample compared other samples. general, showed radical whereas distilled samples Fe 3+ assay.

Organic acid pretreatment has the potential for cleaner production and efficient energy use. This work demonstrated selective separation of hemicellulose lignin from bagasse using lactic (LA), improved processability cellulose. Initially, 0.1% LA hydrolysis converted xylan to xylo-oligosaccharides with a yield 65.0%. Subsequently, was isolated residue by an 80% pretreatment, achieving efficiency 91.2%. Importantly, solid retained high glucan content 88.2%. Following sodium hydroxide incubation, cellulase achieved saccharification 92.5%, which primarily due solubilization pseudolignin de-esterification Additionally, cellulose proved be suitable preparation high-quality dissolving pulp purity Fock reactivity. The recovered solution exhibited (95.7%) contained carboxyl hydroxyl contents, enabling it self-assemble into uniformly sized nanoparticles. Furthermore, even after five cycles reuse, maintained excellent dissolution capacity. Economic assessments also indicated that this process could generate substantial commercial benefits. proposed gradient provided sustainable strategy comprehensive value addition biomass.
