Enzyme-based biosensors are simple, cost-efficient, and easy to use. This review highlights key enzymes with redox-active sites that are suitable for DET processes using various modified electrodes and their applications in biosensors. The review discusses enzyme classification, distinguishing between single-cofactor and multi-cofactor enzymes according to their number of prosthetic groups, with a focus on internal electron transfer processes and the role of redox-active centers. Methods for enzyme immobilization on electrodes are explored with an emphasis on their impact on electron transfer rates in biosensors. A comparison of sensitivity, electron transfer rates, and the linear detection range of molecules (e.g., glucose and lactose) is provided to illustrate the impact of different immobilization techniques on biosensor performance.","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"19 3","pages":"963-981"},"PeriodicalIF":3.2,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The components of DSGH were found to be very complex. The presence of peptides and amino acids reduced the initial thermal decomposition temperature to as low as 197 °C. The activation energy during the initial combustion stage was also low (less than 280 kJ mol−1). Chemical looping gasification, with red mud as an OC, proved feasible for processing DSGH, producing high-quality syngas. Gasification temperature was a more important factor than steam concentration in CLG. The activity of lattice oxygen was more affected by gasification temperature, and steam concentration mainly influenced the process by promoting carbon gasification, methane reforming, and altering the water-gas shift (WGS) equilibrium. A 30-redox-cycle test demonstrated the excellent stability of red mud as an OC, making it a promising candidate for CLG of DSGH.","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"19 3","pages":"806-818"},"PeriodicalIF":3.2,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These polyols were then used to replace 10–30 wt.% of the fossil-fuel-based polyols to formulate flexible polyurethane (PU) foams. It was found that a high molecular weight kraft softwood lignin resulted in a foam with significantly better mechanical properties than foams made with organosolv wheat straw and hydrolysis hardwood lignins. Scanning electron microscopy (SEM) and reaction profile measurements showed that the addition of the lignin polyol decreased foaming times and created foams with smaller cells. Foams produced by replacing 20% of petroleum-based polyols with synthesized kraft softwood lignin polyol passed all the standard requirements for automotive seating applications while containing less isocyanate.","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"19 3","pages":"894-910"},"PeriodicalIF":3.2,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bbb.2750","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the simultaneous production of biochar, soot, and ash from Daniella oliveri bark using a Top-Lit Updraft (TLUD) reactor, with the aim of maximizing resource recovery while minimizing waste. The thermochemical conversion process was optimized to yield three distinct carbonaceous materials. The thermal process was conducted at a peak temperature of 347.34 °C with a total carbonization/combustion time of 150 min. The results demonstrated that the biochar exhibited a porous morphology with high carbon retention, the ash was rich in mineral oxides suitable for soil amendment, and the soot possessed a high surface area, making it a promising candidate for adsorption and catalytic applications. The study introduces an integrated approach to biomass conversion, reducing dependency on external energy sources by utilizing the bark as both feedstock and fuel. This process presents a scalable alternative for biomass utilization, particularly in regions with abundant agricultural waste and limited industrial infrastructure. Its adoption could contribute to circular economy initiatives, enhancing sustainable material recovery while mitigating environmental pollution.","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"19 3","pages":"882-893"},"PeriodicalIF":3.2,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies in this field have concentrated on microbial protein potential; however, this study examines the lipid recovery potential of PNSB-dominated mixed culture biomass derived from gas-to-liquid wastewater treatment. Lipid characterization employed gas chromatography, focusing on the efficacy of esterification processes and solvent selection. The PNSB biomass showed approximately 34.4 ± 4.7% and 33 ± 2.4% lipid content under dim and full light conditions, respectively. Full light conditions enhanced biomass production, resulting in a higher lipid productivity rate (0.145 ± 0.018 gL–1day–1) than dim light conditions (0.068 ± 0.010 gL–1day–1); however, the choice between these conditions presents a tradeoff between maximizing lipid yield and minimizing energy input. Initial attempts using hexane for fatty acid methyl ester (FAME) characterization were ineffective. However, solvents with higher polarity indices, like dichloromethane (DCM) and diethyl ether (DEE), yielded more comprehensive FAME profiles, especially with continuous mixing during esterification. This highlighted the influence of solvent polarity on lipid analysis. Solvent mixtures like DCM–hexane and DEE–hexane further enhanced the FAME profile. Dominant FAME peaks included 11-octadecenoic acid, hexadecenoic acid, methyl stearate, and 9-octadecenoic acid. Terpenes like citronellol and phytol were also present. With a FAME profile similar to that of microalgae, PNSB biomass holds potential for biodiesel production and applications in nutrition, therapeutics, and agriculture.","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"19 3","pages":"819-834"},"PeriodicalIF":3.2,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bbb.2743","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143939110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of agro-residue oilseed cakes as a nutrient source in the growth medium can reduce the cost of enzyme production process. This study aimed to identify an optimal combination of fungal culture and substrate from locally available vegetable oilseed cakes (mustard, groundnut, almond, cottonseed, and coconut) for lipase production in solid-state fermentation (SSF), and to optimize the process. The combination of Rhizopus oryzae NCIM 1212 with coconut oil cake was selected. Variables, such as the concentrations of NaNO3, KCl, K2HPO4, MgSO4, FeSO4, as well as pH, temperature, inoculum size, moisture content, and the addition of olive oil, were screened using a Plackett–Burman design. Significant variables, along with carbon and nitrogen sources, were further optimized using a one-factor-at-a-time approach. Inoculum size, KNO3, and moisture content were optimized through a central composite design. The highest lipase production (29.85 U g−1 ds (dry substrate), a 5.57-fold increase) was achieved at KNO3 2.10% w/w (weight by weight), inoculum size 1.17% v/w (volume by weight), and moisture content 66.79% w/w. Immobilization of the crude enzyme on functionalized magnetic nanoparticles resulted in protein loading of 67 ± 3 μg/mg and activity recovery of 59.15 ± 3.02%. This study provides insights into low-cost enzyme production and its potential applications.","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"19 3","pages":"789-805"},"PeriodicalIF":3.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143939325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
