Toxic effect evaluation of the lead acetate and chromium chloride on anaerobic bacterial metabolism

Revista Facultad de Ingeniería Universidad de Antioquia, 2004
The toxicity of trivalent chromium and lead to anaerobic sludge system was studied. Performed assay was tested in 60 mL serum vials, the toxicity test to succeed in two steps, first with formic acid and then whey powder as a substrate.

Evaluation of Semi-Continuous Anaerobic Fermentation of Alperujo by Methanogenesis Inhibition

Processes
Two methanogenesis inhibition strategies for enhancing volatile fatty acid (VFA) production through the anaerobic fermentation of alperujo, a byproduct of olive oil production, were evaluated. Methanogenesis inhibition was implemented via two different approaches, one by pH adjustment to 5.0 and another one by chemical inhibition using 2 ...

Effects of exogenous CO2 injection on biomethane production in in-situ anaerobic digestion system of coal measure shale

Meitan xuebao
The integration of increasing coal measure gas (CMG) production and CO2 resource utilization aligns with China’s “dual carbon” goals and can also promote the large-scale development and circular growth of the CMG industry.

Salvianolic acid C inhibits methane emissions in dairy cows by targeting MCR and reshaping the rumen microbial community

Journal of Animal Science and Biotechnology
Background Methane (CH4) emissions from ruminants significantly contribute to greenhouse gas effects and energy loss in livestock production. Methyl-coenzyme M reductase (MCR) is the key enzyme in methanogenesis, making it a promising target for CH4 ...

Selective inhibition of methanogenesis by acetylene in single chamber microbial electrolysis cells

Bioresource Technology, 2019
Microbial electrolysis cells (MECs) for hydrogen production exhibit great advantages over many other biohydrogen production techniques in terms of versatility of substrate and hydrogen yield. However, hydrogen and acetate scavenging by methanogens puts forward a great challenge to the application of single chamber MECs when using mixed culture. In this

The effect of Asparagopsis taxiformis, Ascophyllum nodosum, and Fucus vesiculosus on ruminal methanogenesis and metagenomic functional profiles in vitro

Microbiology Spectrum
The ruminant-microorganism symbiosis is unique by providing high-quality food from fibrous materials but also contributes to the production of one of the most potent greenhouse gases—methane.

Methyl-coenzyme M reductase in archaeal methanogenesis: evolution, mechanism, and biotechnological perspectives

Frontiers in Catalysis
Methanogenesis is an anaerobic, energy-conserving metabolism that converts CO2, acetate, and methylated compounds to methane, constituting a key terminal step in the mineralization of organic matter in many oxygen-limited ecosystems.

A combination of microbial electrolysis cells and bioaugmentation can effectively treat synthetic wastewater containing polycyclic aromatic hydrocarbon

Water Science and Technology
The anaerobic biodegradation of polycyclic aromatic hydrocarbons (PAHs) is challenging due to its toxic effect on the microbes. Microbial electrolysis cells (MECs), with their excellent characteristics of anodic and cathodic biofilms, can be a viable way
