Freeze‐dried Lactobacillus spp. improved average daily liveweight gain and reduced methane intensity in growing lambs

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Direct fed microbials (DFM) are natural and safe enteric methane mitigants for ruminant livestock systems. While previous studies have demonstrated the effect of Lactobacillus spp. on methane mitigation, challenges remain in effectively delivering DFM in extensive grazing systems. The objective of this experiment was to evaluate the

A decision support tool for landfill methane generation and gas collection [PDF]

, 2015
This study presents a decision support tool (DST) to enhance methane generation at individual landfill sites. To date there is no such tool available to provide landfill decision makers with clear and simplified information to evaluate biochemical ...

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

Cobalt toxicity in anaerobic granular sludge: influence of chemical speciation [PDF]

, 2008
The influence of cobalt speciation on the toxicity of cobalt to methylotrophic methanogenesis in anaerobic granular sludge was investigated. The cobalt speciation was studied with three different media that contained varying concentrations of complexing ...

Understanding Farmer Behaviour for Successful Climate Change Mitigation in Voluntary Initiatives

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Private and voluntary initiatives, such as voluntary carbon markets, can support public policies aimed at reducing greenhouse gas (GHG) emissions in agriculture. This study investigates the impact of behavioural factors (reluctance to change) and social dynamics (peer imitation) on the adoption of two mitigation practices on Swiss dairy and ...

Methanogenesis from acetate: enrichment studies [PDF]

Applied and Environmental Microbiology, 1978
An acetate enrichment culture was initiated by inoculating anaerobic sludge from a mesophilic methane digestor into a mineral salts medium with calcium acetate as the sole carbon and energy source. This enrichment was maintained indefinitely by weekly transfer into medium of the same composition.

AutoChamber: A broadly accessible 3D‐printed floating chamber to automate measurements of greenhouse gas emissions from surface waters

Methods in Ecology and Evolution, EarlyView.
Abstract Fresh waters provide environmental conditions that favour microbial CO2 and CH4 production, leading to the release of large quantities of greenhouse gases (GHG) to the atmosphere. Despite their importance, these fluxes remain poorly defined, weakening estimates of global GHG budgets that are critical in implementing effective climate ...

Methanogenesis in the presence of oxygenic photosynthetic bacteria may contribute to global methane cycle

Nature Communications
Accumulating evidences are challenging the paradigm that methane in surface water primarily stems from the anaerobic transformation of organic matters.

Terrestrial and fluvial carbon fluxes in a tropical watershed: Nyong basin, Cameroon [PDF]

, 2009
The Nyong watershed, with an area of 27 800 km2 and a mean annual discharge of 390 m3 s−1, is the second largest river in Cameroon. The Nyong watershed serves as an outstanding study area for the examination of carbon fluxes in humid tropical ...

Effect of Moderate Heat on TCE Reductive Dechlorination Rates in Groundwater

Groundwater Monitoring &Remediation, EarlyView.
Abstract Low‐temperature heating (in the mesophilic range of ~15 to 40 °C) of contaminated aquifers offers the prospect of increasing the rates for biotic and abiotic treatment of volatile organic compounds. Thermal In Situ Sustainable Remediation (TISR®) is one of the approaches available to implement low temperature heating.
