Methane-related changes in prokaryotes along geochemical profiles in sediments of Lake Kinneret (Israel) [PDF]

Biogeosciences, 2015
Microbial methane oxidation is the primary control on the emission of the greenhouse gas methane into the atmosphere. In terrestrial environments, aerobic methanotrophic bacteria are largely responsible for this process.

Bioactive compounds in insects—Composition, extraction, functionality, food applications, and safety concerns

Food Biomacromolecules, EarlyView.
This review synthesizes 94 studies (2000–2025) exploring edible insects as sustainable sources of peptides, lipids, and chitin. Utilizing “green” extraction, these bioactives offer antioxidant and antimicrobial benefits for functional foods. However, addressing safety concerns like allergenicity and heavy metals through standardized frameworks remains ...

Selective, Aerobic Oxidation of Methane to Formaldehyde over Platinum ‐ a Perspective

ChemCatChem, 2023
AbstractThe direct formation of formaldehyde in the selective, aerobic oxidation of methane in the presence of liquid water at ca. 498 K has recently been described. One of the intriguing observations in the aerobic oxidation of methane over platinum in the presence of water is the absence of the typically observed negative selectivity‐conversion ...

Evaluation of methods for the analysis of oxygen and carbon dioxide in water, sediment, litter, and soil

Limnology and Oceanography: Methods, EarlyView.
Abstract Choosing an appropriate analyzer to measure concentrations of oxygen (O2) and carbon dioxide (CO2) during biogeochemical cycling studies can be difficult, considering the range of options available. While several studies examine the abilities of specific analyzers, comparison of multiple analyzers and environmental sample types is lacking.

Reducing Ammonia Emission during Food Waste Composting and Enhancing Compost Quality Using Different Additives

ChemistryOpen, EarlyView.
This research successfully reduces the ammonia emission by 45% and achieves good quality compost using additives (lactic acid or acetic acid) and bulking agents (mature compost or sawdust). The study supports Sustainable Development Goals 12 and 13 by promoting waste‐to‐resource option.

A genomic view of methane oxidation by aerobic bacteria and anaerobic archaea.

Genome biology, 2005
Recent sequencing of the genome and proteomic analysis of a model aerobic methanotrophic bacterium, Methylococcus capsulatus (Bath) has revealed a highly versatile metabolic potential. In parallel, environmental genomics has provided glimpses into anaerobic methane oxidation by certain archaea, further supporting the hypothesis of reverse ...

Seasonal Variation in Carbon Dynamics in the Lower Tocantins River: Influence of Discharge and Environmental Drivers

River Research and Applications, EarlyView.
ABSTRACT Tropical rivers play a key role in regional carbon budgets, yet greenhouse gas (GHG) dynamics in regulated systems remain poorly understood. This study investigates the seasonal variability of carbon dioxide (CO2) and methane (CH4) concentrations, isotopic composition (δ13C), and river‐atmosphere fluxes in the lower Tocantins River, a ...
