Shifts in metabolic hydrogen sinks in the methanogenesis-inhibited ruminal fermentation: a meta-analysis

Frontiers in Microbiology, 2015
Maximizing the flow of metabolic hydrogen ([H]) in the rumen away from CH4 and towards volatile fatty acids (VFA) would increase the efficiency of ruminant production and decrease its environmental impact. The objectives of this meta-analysis were: i) To

Biogas production from Opuntia stricta Haw.: microbial diversity and solid load influence on sludge recycle systems

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The search for alternative and sustainable energy sources becomes urgent as energy demand increases and fossil fuels become less available, especially in water‐scarce regions such as the Brazilian semi‐arid region, where current projections of global warming and the expansion of arid and semi‐arid zones point to a future of desertification ...

Inhibition of tetrachloroethene and trichloroethene on methanogenesis in anaerobic sludges from various origins [PDF]

Water Science and Technology, 2020
Abstract Nine anaerobic sludges were screened to obtain the most effective methanogenic inoculum for the anaerobic treatment of groundwater that is contaminated with tetrachloroethene (PCE) or trichloroethene (TCE). The selection was based on the toxicity of PCE or TCE to acetoclastic methanogens in different sludges.

Increasing the Production of Volatile Fatty Acids from Corn Stover Using Bioaugmentation of a Mixed Rumen Culture with Homoacetogenic Bacteria

Microorganisms, 2021
Volatile fatty acids (VFA) are industrially versatile chemicals and have a major market. Although currently produced from petrochemicals, chemical industries are moving towards more bio-based VFA produced from abundant, cheap and renewable sources such ...

Effects of Fertilization and Wheat Straw Management on Rice Yield and Greenhouse Gas Emissions in Paddy Fields

Land Degradation &Development, EarlyView.
ABSTRACT Environmental pollution caused by excessive nitrogen fertilization has become increasingly serious, making optimized fertilization and straw management critical for improving agricultural sustainability. This study involved a two‐year field trial with three fertilization strategies: conventional fertilization (CF), 23.50% nitrogen reduction ...

Delivering Sulfate to LNAPL Body for Enhanced Source Zone Depletion (ESZD)

Groundwater Monitoring &Remediation, EarlyView.
Abstract This field pilot study evaluates the feasibility of applying sulfate to a light non‐aqueous phase liquid (LNAPL) body for achieving enhanced source zone depletion (ESZD) at a refinery site. Two rounds of gypsum land application (GLA) delivered sulfate to an 8000 ft2 area encompassing LNAPL‐containing monitoring wells MW‐2 and MW‐3, while MW‐1 ...

Inhibition of methanogenesis by ethylene and other unsaturated hydrocarbons [PDF]

FEMS Microbiology Letters, 1985
1. SUMMARY Ethylene (ethene) was found to inhibit methane formation in slurries from sewage sludge and sediment samples taken from freshwater and marine sources. Methane formation from sediment contents was inhibited by 50% at 0.07% ethylene concentration in the gas phase (approx.

3-Nitrooxypropanol substantially decreased enteric methane emissions of dairy cows fed true protein- or urea-containing diets

Heliyon, 2022
Methane is a potent but short-lived greenhouse gas targeted for short-term amelioration of climate change, with enteric methane emitted by ruminants being the most important anthropogenic source of methane.

Archaeal Genes Code for GGDEF Domain Proteins With Diguanylate Cyclase Activity

Molecular Microbiology, EarlyView.
A biofilm‐like mode of growth is hypothesized to be required for the emergence of cellular life. Occurrence of common biofilm gene products in current Bacteria and Archaea is an indication for their previous presence in the last universal common ancestor LUCA and perhaps even in the first universal common ancestor FUCA.
