ACS ES&T Engineering, Год журнала: 2025, Номер unknown

Опубликована: Март 30, 2025

Effective management of food waste (FW) is essential for achieving energy self-sufficiency and carbon neutrality in treatment plants (FWTPs). Developing a multitandem efficient FW process crucial performing more recovery at on-site plants. In this study, cascading was developed to treat from generation complete disposal. Compared with the unpretreated (UP-FW), enzymolysis exhibited higher hydrolysis efficiencies FW. Specifically, concentrations glucose, chemical oxygen demand, total organic increased by 259.42%, 49.31%, 33.08%, respectively. The pretreated considerable hydrogen yield 35.81 ± 1.47 mL/g-VS, roughly double that raw used as substrate, which also accompanied 26.52% 19.10% increases ethanol acetate production, recyclable catalyst (FRB800) pyrolyzed fermentation residue showed superior Orange G (OG) removal efficiency better anti-interference ability actual water body. OG could be completely removed within 30 min, dominated singlet oxygen, nonradical pathways, diverse active sites on FRB800. This synchronizes resources degradation pollutants. Overall, these findings indicate an alternative approach disposal possesses significant engineering value broad application prospects FWTPs.

Electron Donor-Driven Microalgae Upgrading into High-Value Fatty Acids via a Microbial Platform

ACS ES&T Engineering, Год журнала: 2024, Номер unknown

Опубликована: Окт. 24, 2024

The efficient treatment and energy recovery from salvaged microalgae have been imperative considering both environmental economic concerns. Herein, this study proposed a biotechnological platform for converting into medium-chain fatty acids (MCFAs) through anaerobic fermentation as well exploring the roles of different electron donors (EDs). After various ED combinations, results suggested that single ED, especially sole ethanol stimulation, exhibited more pronounced stimulation effects on MCFA production compared to those hybrid stimulations. Furthermore, lactic acid served basis formation longer-chain alcohols odd-chain in liquid products, respectively. dynamics thermodynamics analyses confirmed distinctions accumulation trends saturated compositions main products under compositions. Moreover, mechanistic investigations revealed differences chain elongation efficiency genome-based metabolic potential microbial systems contributed intricate feedback regulations biochemical reactions scenarios. Overall, provided valuable insights sustainable conversion by orienting toward high-value biochemicals, serving theoretical selection optimization before industrial application.
