However, methane recovery alone may not offset the high energy demand required to maintain thermophilic conditions. Converting PLA into value-added intermediates, such as lactate, could improve the economic viability of PLA upcycling. In this study, we investigated whether low-CO<ce:inf loc=\"post\">2</ce:inf> condition could redirect carbon flux toward lactate production during PLA-degrading TAD. A low-CO<ce:inf loc=\"post\">2</ce:inf> condition was established by <ce:italic>in situ</ce:italic> absorption of headspace CO<ce:inf loc=\"post\">2</ce:inf> using NaOH pellets. Under reduced CO<ce:inf loc=\"post\">2</ce:inf> conditions, substantial lactate accumulation occurred, whereas methane yield decreased only moderately (≈11%), indicating that methanogenesis was largely maintained. Carbon distribution and volatile fatty acid (VFA) profiles suggested a thermodynamically driven shift in metabolic pathways that favored lactate accumulation without severely disrupting syntrophic VFA oxidation. Microbial community analysis revealed pronounced changes in bacterial populations associated with PLA hydrolysis and fermentation, whereas archaeal communities remained relatively stable, consistent with sustained methanogenic activity. These findings suggest that headspace CO<ce:inf loc=\"post\">2</ce:inf> control can steer intermediate production during anaerobic digestion, enabling simultaneous methane generation and recovery of the value-added product, lactate from PLA waste. Although challenges related to product titers and operational costs remain for large-scale implementation, this proof-of-concept strategy provides a promising pathway to improve the resource recovery efficiency and economic feasibility of thermophilic PLA treatment systems.","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"1 1","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148692486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The accumulation of divalent AAEMs in PW significantly increases the hydrochar (HC) yield, while all AAEMs enhance the HAs yield.

The divalent AAEMs cause a slight blue shift of HAs in 3D EEM, indicating lower aromatic condensation and molecular weight.

Although traditional extraction methods are commonly used, newer green extraction techniques offer improved extraction efficiency by reducing energy and solvent consumption leading to higher extraction yields. This study explores an application of ultrasound-assisted extraction, a green technique, in extraction of phytoconstituents from <em>Psidium guajava</em> leaves, optimizing key parameters such as extraction time, temperature, ultrasonic input power, and solvent ratio. Additionally, the study evaluates the antioxidant properties and significant antidiabetic activity of the extracted compounds. The extraction of <em>Psidium guajava</em> Linn. leaves were optimized for enhance yield, which was obtained at 40 °C at the end of 45 min of extraction time with a solvent ratio of 60:40 (methanol: water) among several batches. At this optimized condition 38.7% extraction was achieved and yielded the highest amount of flavonoids which is 229.31 mg/g with the use of ultrasound extraction and the delivered power was 173.2 W. Ultrasound-assisted extraction significantly enhances the yield of phytoconstituents, especially flavonoids, and found promising for managing Type 2 diabetes mellitus. The biochemical analysis revealed that the flavonoids reduce blood glucose levels more effectively than the diabetic control. However, while these extracts are effective, these are still less potent than the standard antidiabetic drug sitagliptin, indicating that it may be more suitable as complementary therapies rather than standalone treatments.</div></div>","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"211 ","pages":"Article 109239"},"PeriodicalIF":5.8,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147387619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores an external H₂-free hydrothermolysis pathway for palm oil conversion into bio-jet fuel-range hydrocarbons using a series of Ni catalysts supported on dealuminated HUSY zeolites in alcohol–water co-solvent systems. Effects of HUSY dealumination via nitric acid treatment (0.05–0.15M) on catalyst properties and hydrocarbon selectivity were evaluated. Comprehensive characterization using various techniques revealed that dealumination at 0.10M HNO₃ generated an optimal balance of acidity, porosity, and Ni dispersion, while milder and harsher treatments led to side reactions and partial framework collapse. Methanol addition enhanced <em>in situ</em> hydrogen generation and hydrodeoxygenation (HDO), whereas excess methanol promoted esterification and accumulation of corresponding fatty acid methyl esters.
