Energy security improves, environmental impacts diminish when bioethanol, a biofuel produced via lignocellulose-based processes, is utilized. The lignocellulosic of Thysanolaena latifolia considerable potential bioethanol feedstock due to its high carbohydrate content (62.4 ± 0.7%). In this study, derived from T. was pretreated with various concentrations H3PO4 determine the ideal conditions for enzymatic hydrolysis convert fermentable sugar. findings revealed efficiency glucose recovery yields were substantially improved compared those untreated sample. Pretreated samples enzymatically digested produce liquid hydrolysate. This hydrolysate fermented without detoxification using Saccharomyces cerevisiae TISTR 5339 ethanol. results indicated promising long-term carbon ethanol production cellulosic biomass. Furthermore, morphological crystallographic characteristics treated influenced by concentration, SEM images, X-ray diffractogram patterns, crystallinity index values. Therefore, utilizing enhance bioenergy sustainability.

The effective utilization of nonfood biomass for bioethanol production represents a promising strategy sustainable energy development. Moreover, limited research has been conducted on broom grass (Thysanolaena latifolia) as potential feedstock production, particularly regarding the effects NaOH autoclave pretreatment its enzymatic digestibility and fermentability. This study optimized sodium hydroxide (NaOH) combined with autoclaving to enhance biomass. concentration (1–4%) temperature (110–130 °C) composition, structural features, hydrolysis were systematically evaluated. Pretreatment 2% at 120 °C emerged optimal, achieving 74.7% lignin removal 93.2% glucan recovery, thereby significantly improving efficiency (88.0%) glucose recovery (33.3%). Scanning electron microscopy (SEM) X-ray diffraction (XRD) analyses revealed that these improvements attributed increased surface porosity selective amorphous components while maintaining cellulose crystallinity. pretreated hydrolysate exhibited excellent production. Fermentation using Saccharomyces cerevisiae TISTR 5339 achieved an 86.4% ethanol conversion rate, yielding 147 g per 1000 representing 2.6-fold increase compared untreated feedstock. These findings demonstrate in enhancing from biomass, aiding advancement cost-effective lignocellulosic biorefinery processes. presents opportunity valorize this multifaceted plant expand beyond traditional uses.

Cellulosic ethanol has been an attractive biofuel for over a century. Despite the large scientific interest, first step of treating cellulose before enzymatic hydrolysis is still inadequate, so community seeks innovative solutions. Among them, plasma treatment raw represents interesting approach. The literature on approaches to treat with gaseous surveyed, and results reported by different authors are interpreted. Reactive particles like ions, electrons, metastables, radicals interact chemically surface but do not cause significant depolymerization bulk cellulose. Such from bond scission in energetic species capable penetrating deep into photons range vacuum ultraviolet radiation (photon energy above threshold scission) most suitable formation water-soluble fragments, which further hydrolysis.
