Lime-assisted hydrothermal humification and carbonization of sugar beet pulp: Unveiling the yield, quality, and phytotoxicity of products

Biofuel Research Journal, Journal Year: 2024, Volume and Issue: 11(01), P. 2025 - 2039

Published: March 1, 2024

Hydrothermal carbonization (HTC) solid and liquid products may inhibit seed germination, necessitating post-treatment. The hydrothermal humification (HTH) method addresses this drawback by transforming inhibitory compounds, such as aromatics, into artificial humic acids (AHAs) fulvic (AFAs). This study introduces a novel approach investigating the substitution of commonly used alkaline agent in HTH, KOH, with hydrated lime to develop cost-effective fertilizers from sugar beet pulp, enriching them AHAs. It assesses effects on AHA production soluble organic compounds compared KOH. results indicate that significantly reduces furans (from 560 3.15 mg/kg DM 344 3.86 mg/L process liquid) boosts sugars acids, especially lactic acid 4.70 65.82 g/kg 4.05 22.89 liquid), increasing hydrochar yield (68.8% vs. 27.4% KOH). Despite lower KOH (3.47% 15.50%), lime-treated are abundant calcium magnesium, boasting pH 7. property presents safer more efficient alternative fertilizers. characterization AHAs aligns standard natural substances, while lime-assisted HTH products, applied at level 0.01% w/w, could enhance wheat growth nutrient uptake control group. Importantly, these show no toxicity Daphnia magna, underscoring their potential for sustainable agriculture.

Hydrothermal Carbonization Technology for Wastewater Treatment under the “Dual Carbon” Goals: Current Status, Trends, and Challenges

Water, Journal Year: 2024, Volume and Issue: 16(12), P. 1749 - 1749

Published: June 20, 2024

Hydrothermal carbonization (HTC) technology transforms organic biomass components, such as cellulose and lignin, into valuable carbon materials, gases inorganic salts through hydrolysis, degradation polymerization, with significant advantages over traditional methods by reducing energy consumption, lowering pollutant emissions enhancing efficiency. In the context of global climate change, HTC plays a critical role in water environment management addressing industrial, agricultural, domestic wastewater challenges. The application extends to treatment, where hydrochar effectively adsorbs heavy metals, compounds, anions, thereby improving quality. However, challenges remain, optimizing process for diverse raw managing economic costs, environmental social impacts. Future research policy support are essential advancing technology. By reaction mechanisms, developing catalysts, promoting international cooperation, can significantly contribute towards achieving neutrality goals fostering sustainable development.

Deciphering the role of substrate carbon to nitrogen ratio in preventing orange mold contamination caused by Neurospora sitophila in mushroom cultivation

Frontiers in Industrial Microbiology, Journal Year: 2025, Volume and Issue: 2

Published: Jan. 6, 2025

Introduction Mold contamination, particularly from green and orange molds, poses a serious threat during the growing stage in mushroom cultivation, exacerbated throughout hot humid summer months. Despite extensive studies on mold, mold remains underexplored. Consequently, this study comprehensively investigated focusing identifying causal agent, assessing its pathogenicity, exploring potential countermeasures. Methods Internal transcribed spacer (ITS) region sequencing was used to confirm causative entity, while dual confrontation plate method employed assess pathogenicity. Furthermore, control strategies, including plant extract, vitro media performance, substrate characteristics, were explored. For estimated qualities, Fourier-transform infrared spectroscopy (FTIR) scanning electron microscopy (SEM) studies, along with analysis of physicochemical properties C:N ratio, carbon, protein, mineral content assessed. Results The result confirmed Neurospora sitophila as entity. pathogenicity assessments indicated that impedes colonization mycelium by competing for nutrients space. in-vitro performance demonstrated growth inhibited at varying rates nitrogen supplemented presence available carbon. Notably, SEM revealed heavily colonized sawdust but not rice straw, attributed higher ratio sawdust. Discussion These findings suggest lower negatively affects growth, highlighting supplementation or using straw effective strategies manage contamination cultivation. This strategy could also be applied other food industries where is used.

Unlocking the Potential of Vinegar Residue: A Novel Biorefining Strategy for Amino Acid-Enriched Xylooligosaccharides and Humic-Like Acid

Published: Jan. 1, 2024

In order to address the issue of low amino acid retention in production xylooligosaccharides (XOS) through hydrothermal pretreatment at high temperatures, a novel approach combining temperature hydrolysis and enzymatic was employed. This innovative method not only allows for acid-rich XOS, but also yields valuable byproduct known as humic-like (HLA) from vinegar residue (VR). Under optimal conditions (89°C, 6 h, 1.2% sulfuric acid), yield XOS 19.88%. Furthermore, hydrolyzate extracted pretreated VR had content 2.65 g/L acids (corresponding rate 82.0%), HLA sample 10.51%. Comprehensive analyses, such Fourier transform infrared spectroscopy, elemental analysis, total acidic functional group, nuclear magnetic resonance were employed examine structure composition produced HLA, indicating that it similar natural CHA minerals. Through this approach, offers sustainable solution addresses maximizes potential resource.
