Valorization and Kinetic Modelling of Pediocin Production from Agro and Dairy Industrial Residues by Pediococcus pentosaceus CRA51
Waste and Biomass Valorization - - Trang 1-22 - 2023
Pediocin (PE) is an antimicrobial peptide possessing a plethora of applications in food preservation. In this study, an economical and sustainable method for the production of PE by Pediococcus pentosaceus CRA51 was achieved by utilizing low-cost renewable feedstocks and industrial by-products viz., Palmyra palm jaggery (PJ), Cassava fibrous waste hydrolysate (CFWH) and Whey protein hydrolysate (W......
Environmental Life Cycle Assessment of Hydrothermal Carbonization of Sewage Sludge and Its Products Valorization Pathways
Waste and Biomass Valorization - Tập 13 - Trang 3845-3864 - 2022
This study is aimed at evaluating through Life Cycle Assessment (LCA) the environmental performances of an integrated system of an existing Water Resources Recovery Facility (WRRF) and a hypothetical hydrothermal carbonization (HTC) plant applied to the generated sewage sludge (SS). Beside the valorisation of the solid product (hydrochar, HC) as a fuel substituting lignite, the possibility to valo......
Biocatalyzed Vinyl Laurate Transesterification in Natural Deep Eutectic Solvents
Waste and Biomass Valorization - - Trang 1-12 - 2023
Natural deep eutectic solvents (NADES) represent a green alternative to conventional organic solvents as reaction medium, offering more benign properties. To efficiently design NADES for biocatalysis, a better understanding of their effect on these reactions is needed. We hypothesize that this effect can be described by separately considering (1) the solvent interactions with the substrates, (2) t......
Methane Production from the Co-digestion of Algal Biomass with Crude Glycerol by Anaerobic Mixed Cultures
Waste and Biomass Valorization - Tập 11 - Trang 1873-1881 - 2018
The optimization of factors affecting methane production from the co-digestion of algal biomass with crude glycerol was investigated using response surface methodology with a central composite design. The investigated parameters included algal biomass, crude glycerol and inoculum concentration. The inoculum and algal biomass concentration had a significant individual effect on the methane producti......
Effect of Operating Conditions on the Coke Formation and Nickel Catalyst Performance During Cracking of Tar
Waste and Biomass Valorization - Tập 10 - Trang 155-165 - 2017
Catalytic cracking of toluene as a tar model compound was carried out to investigate the effect of operating conditions on the coke formation and performance of nickel catalyst. The deactivation of catalyst depended on the quantity and nature of deposited coke, which were affected by the operating conditions, including temperature, nickel and steam concentration. The highest yield ratio of filamen......
Development of a Biodegradable/Ecofriendly Turbine Lubricant from a Novel Polyalkylene Glycol Ester
Waste and Biomass Valorization - Tập 9 - Trang 1121-1128 - 2017
A biodegradable/ecofriendly polyalkylene glycol ester 1,2-PTHC6 (polyglycol containing 1:2 mol fraction of propylene oxide (PO) and tetrahydrofuran (THF)) esterified with n-hexanoic acid (C6 fatty acid) was synthesized following the two step reaction. At first, propylene oxide and tetrahydrofuran were polymerized in 1, 2-dichloroethane to obtain a polymer 1,2-PTH (polyglycol containing 1:2 mol fra......
Batch and Column Adsorption of Reactive Red 198 from Textile Industry Effluent by Microporous Activated Carbon Developed from Walnut Shells
Waste and Biomass Valorization - Tập 7 - Trang 1255-1270 - 2016
In this study, the adsorption potential of walnut shells (WNS) was investigated using batch and fixed-bed column. Activated carbons (ACs) were prepared from WNS as a precursor for by chemical activation with H3PO4 and KOH with different impregnation ratios for removing reactive red 198 from wastewater. The surface characteristics of the prepared ACs were determined by the analysis of N2 adsorptio......
Comparison of Traditional and Modern Techniques for Betalains Extraction from Amaranth Agro-Industrial Waste: The Recovery of High Value By-Products
Waste and Biomass Valorization - - 2024
The increasing demand for healthier food has boosted the amaranth cultivation for the production of edible grains. However, after the grain is harvested, the leaves are considered agro-industrial waste and are left on the soil, but those leaves have a high potential for the recovery of high value by-products such as betalains. Betalains are natural dyes with important uses in food and pharmaceutic......
The Effect of Preparing Temperature and Atmosphere on Biochar’s Quality for Soil Improving
Waste and Biomass Valorization - Tập 10 - Trang 1395-1405 - 2017
To investigate how to influence the biochar quality for improving soil by the preparing temperature and atmosphere, biochar samples were produced from rice straw at different temperatures (300, 400, 600 and 800 °C) and different pyrolysis atmospheres (N2 and CO2). Other researchers all did not use CO2 to produce the biochar for improving the chemical and physical properties of soil. Through these ......
