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

open access: yesBiofuels, 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 ...

Ex Situ Culturing Experiments Revealed Psychrophilic Hydrogentrophic Methanogenesis Being the Potential Dominant Methane-Producing Pathway in Subglacial Sediment in Larsemann Hills, Antarctic

open access: yesFrontiers in Microbiology, 2018
It was recognized only recently that subglacial ecosystems support considerable methanogenic activity, thus significantly contributing the global methane production.

Magnetite drives microbial community restructuring and stimulates aceticlastic methanogenesis of type II Methanosarcina in mangrove sediments

open access: yesMicrobiome
Background Mangrove wetlands are critical hotspots of methane emissions, yet the role of naturally occurring minerals in shaping their microbial communities and methanogenic processes is poorly understood.

Biochar and Hydrochar as Soil‐Based Carbon Sequestration Technologies: Implications for Greenhouse Gas Mitigation

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Biochar and hydrochar have emerged as promising carbon‐based amendments for enhancing soil carbon sequestration and mitigating greenhouse gas emissions. This review synthesizes and critically compares current knowledge on the production technologies, physicochemical properties, stabilization mechanisms, carbon persistence, and life‐cycle ...

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

open access: yesLand 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 ...

Seasonal Dynamics of Community and Function of Gut Microbiome in Taihangshan Macaque (Macaca mulatta tcheliensis): Inferred From Metagenomic Data

open access: yesIntegrative Zoology, EarlyView.
A total of 435 non‐redundant metagenome‐assembled genomes (MAGs) were obtained from fecal samples of Taihangshan macaque across all four seasons. The alpha diversity of the gut microbiome in spring and winter was significantly higher than in summer and autumn. Furthermore, marked differences were detected in functional pathways and carbohydrate enzymes

A phenotype‐based framework to measure functional redundancy in microbial ecosystems

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Functional redundancy is a key biological concept that offers critical insights into microbial ecosystem stability and responses to environmental perturbations. Existing methods to quantify redundancy typically rely on gene annotations as functional units, limiting their ability to capture complex or partially characterised traits and making ...

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen

open access: yesThe FEBS Journal, EarlyView.
Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,

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

open access: yesGroundwater 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 ...
