In Vivo Evidence of Single 13C and 15N Isotope–Labeled Methanotrophic Nitrogen-Fixing Bacterial Cells in Rice Roots

mBio, 2022
Methane-oxidizing bacteria (methanotrophs) play an ecological role in methane and nitrogen fluxes because they are capable of nitrogen fixation and methane oxidation, as indicated by genomic and cultivation-dependent studies.

Potential bioethanol and biogas production using lignocellulosic biomass from winter rye, oilseed rape and faba bean [PDF]

, 2007
To meet the increasing need for bioenergy several raw materials have to be considered for the production of e.g. bioethanol and biogas.In this study, three lignocellulosic raw materials were studied, i.e.

Anaerobic Oxidization of Methane in a Minerotrophic Peatland: Enrichment of Nitrite-Dependent Methane-Oxidizing Bacteria [PDF]

Applied and Environmental Microbiology, 2012
ABSTRACT The importance of anaerobic oxidation of methane (AOM) as a methane sink in freshwater systems is largely unexplored, particularly in peat ecosystems. Nitrite-dependent anaerobic methane oxidation (n-damo) was recently discovered and reported to be catalyzed by the bacterium “ Candidatus ...

Anaerobic methane oxidation is an important sink for methane in the ocean's largest oxygen minimum zone

Limnology and Oceanography, 2019
We investigated methane oxidation in the oxygen minimum zone (OMZ) of the eastern tropical North Pacific (ETNP) off central Mexico. Methane concentrations in the anoxic core of the OMZ reached ~ 20 nmol L−1 at off shelf sites and 34 nmol L−1 at a shelf ...

Combining Electrochemical Reduction with Biosynthesis for Directed Conversion of CO2 into a Library of C3 Chemicals

Advanced Science, EarlyView.
In the H‐type electrolytic cell, carbon dioxide is reduced to acetic acid via electro‐microbial catalysis. The simply processed acetic acid is further converted through biological fermentation into high‐value‐added products, including acrylic acid, L‐lactic acid, and β‐alanine.

Diagnosis of an anaerobic pond treating temperate domestic wastewater: An alternative sludge strategy for small works [PDF]

, 2014
An anaerobic pond (AP) for treatment of temperate domestic wastewater has been studied as a small works sludge management strategy to challenge existing practice which comprises solids separation followed by open sludge storage, for up to 90 days. During

Ensiling and Fermentation of Rice Hulls With Ruminal Fluid for Medium‐Chain Carboxylate Production

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Large quantities of rice hulls are common at milling sites in Nigeria. They are a by‐product of rice processing and can contribute to environmental degradation if not properly managed. In this study, rice hulls were pretreated by ensiling at ambient temperature and then used as substrate for medium‐chain carboxylates (MCCs) production ...

Methane Generation Using an Anaerobic Biodigester From Waste Leachate Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Leachate wastewater (LWW) is characterized by slow biodegradation and low biogas production due to resistant materials and limited biological activity. Therefore, applying pretreatments is essential to improving biodegradation potential, which consequently boosts energy recovery.

Significance of anaerobic oxidation of methane (AOM) in mitigating methane emission from major natural and anthropogenic sources: a review of AOM rates in recent publications

Environmental Science: Advances, 2022
AOM rates in literature were analyzed and anaerobic methanotrophs significantly cut methane emissions in oceans but not in wetlands, rice paddy, and fresh water. The trophic and metabolic patterns of microorganisms may be limiting the AOM rates.

Integrated Evaluation of Contaminant Profiles, Detection Techniques, and Management Strategies for Tannery Sludge

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This review article critically examines the environmental and health hazards of tannery sludge (TS), a complex by‐product of the leather tanning industry. TS is characterized by a diverse array of contaminants, including heavy metals like chromium, organic pollutants such as polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds ...
