Impacts of 2-bromoethanesulfonic sodium on methanogenesis: Methanogen metabolism and community structure

Shuang Qiu et al.

Summary: Production of medium-chain carboxylic acids (MCCAs) through chain elongation (CE) offers a competitive alternative to conventional methane products in anaerobic digestion of organic waste. This study investigated the effects of 2-bromoethanesulfonic sodium (BES) on methanogenesis in granular sludge and found that 3.0 g/L BES significantly reduced methane production by suppressing metabolic pathways and intracellular regulations. BES inhibited electron transport and affected energy metabolism, leading to decreased ATP synthesis and enhanced ATP consumption. Additionally, BES favored hydrogenotrophic methanogenesis over acetoclastic one and reduced the protein and carbohydrate contents in extracellular polymeric substances (EPS).

Biosynthesis of poly(3-hydroxybutyrate-co-3-hydroxvalerate) from volatile fatty acids by Cupriavidus necator

Fanfan Cai et al.

Summary: The study investigated the synthesis of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) by Cupriavidus necator using volatile fatty acids (VFAs) as the carbon source. The concentration and composition of VFAs were found to significantly affect the production and composition of PHAs. Odd carbon VFAs (propionate and valerate) resulted in PHBV production, with the 3-hydroxyvalerate (3HV) content determined by the specific VFAs compositions. Optimization using response surface methodology achieved the highest PHBV accumulation of 79.47% in dry cells, with a VFAs to PHBV conversion efficiency of 40%.

Application and improvement methods of sludge alkaline fermentation liquid as a carbon source for biological nutrient removal: A review

Zehui Yin et al.

Summary: Alkaline fermentation can produce sludge alkaline fermentation liquid (SAFL) rich in short-chain fatty acids (SCFAs), which can be used as a high-quality carbon source for the biological nutrient removal (BNR) process. SAFL has advantages of higher efficiency and economy compared to traditional carbon sources, and different operating conditions affect the yield and structure of SCFAs in SAFL. SAFL significantly improves the nutrient removal efficiency of the BNR process and can solve the problems of carbon source shortage and sludge treatment difficulties in wastewater treatment plants.

Redirecting carbon to recover VFA to facilitate biological short-cut nitrogen removal in wastewater treatment: A critical review

Da Kang et al.

Summary: Wastewater treatment plants are seeking to transition to carbon-neutral and energy-efficient systems. Carbon limitation can severely impact biological nutrient removal, particularly in wastewater with a low carbon-to-nitrogen ratio. Waste activated sludge is a valuable byproduct that can be used to improve biological nutrient removal by recovering and reusing volatile fatty acids. This review provides a comprehensive examination of the recovery and reuse of VFAs in wastewater management, with a focus on the biological shortcut nitrogen removal process.

A Review on Performance Improvement of Anaerobic Digestion Using Co-Digestion of Food Waste and Sewage Sludge

Archana Paranjpe et al.

Summary: Anaerobic co-digestion is an important technology for processing organic waste, recovering nutrients, and creating sustainable biofuel. However, the low biogas output and high installation costs limit its viability. This literature review demonstrates that anaerobic co-digestion produces more methane biogas than anaerobic digestion, and adjusting the waste-to-water waste ratio can increase methane production.

Insights into thermal hydrolysis pretreatment temperature for enhancing volatile fatty acids production from sludge fermentation: Performance and mechanism

Zhuangzhuang Xiang et al.

Summary: By conducting four groups of experiments with different temperatures (100, 120, 140, and 160 degrees Celsius) of thermal hydrolysis pretreatment (THP) and utilizing high throughput sequencing technology, this study reveals the impact of THP temperature on the mechanisms of volatile fatty acids (VFAs) production. The results show that the optimal VFAs production occurs at 140 degrees Celsius. Mechanism investigations indicate that THP facilitates the hydrolysis and release of biodegradable organic matter, and improves the abundance of VFAs production, hydrolytic microorganisms, and related metabolic functional genes expression. This study deepens the understanding of how different THP temperatures stimulate the production of VFAs through acidogenic fermentation, providing technical support for future THP application in sludge treatment.

Particle size effects in microbial characteristics in thermophilic anaerobic digestion of cattle manure containing copper oxide

Yuanyuan Lu et al.

Summary: This study investigated the roles of different particle sizes of copper oxide (CuO) in thermophilic anaerobic digestion (AD) on methane production, microbial diversity, and functions. The results showed that bulk-, micron-, and nano-CuO had varying degrees of promotion on methane production. Microbial community analysis revealed that different particle sizes of CuO affected bacterial community composition more than archaeal diversity. Metabolic pathway analysis showed that only the micron-CuO promoted energy-related metabolism and material transformation in bacteria, while nano-CuO and bulk-CuO were important for methanogenic activity and methane metabolism, respectively.

Techno-economic Assessment of Biogas Project: a Longitudinal Case Study from Japan

Jian Wang et al.

Summary: The development of biomass for energy production is encouraged on a large scale in local cities and developing nations, but many projects still face challenges in terms of financial imbalance, particularly due to narrow revenues and high expenditures. A specific biogas project in Japan, investigated in this study, showed that equipment depreciation costs and aging issues were major factors impacting operation performance. Proposed solutions include changing feedstock of biomass wastes, promoting consumption of fertilizer byproducts, and implementing integrated waste management. The optimal scenario for the project resulted in an internal rate of return of 1.31% and a simple payback period of 26.9 years.
