An identity card for sabkha dolomite

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
An ‘identity card’ for modern sabkha dolomite from Qatar reveals its mineralogical, geochemical and microbial characteristics. This integrated dataset provides a benchmark for recognising similar dolomites in the rock record and for calibrating paleoenvironmental proxies used in climate and biosignature studies.

Bacterial community analysis in upflow multilayer anaerobic reactor (UMAR) treating high-solids organic wastes [PDF]

open access: yes, 2017
A novel anaerobic digestion configuration, the upflow multi-layer anaerobic reactor (UMAR), was developed to treat high-solids organic wastes. The UMAR was hypothesized to form multi-layer along depth due to the upflow plug flow; use of a recirculation ...

Sustainable Pretreatment of Food Waste for Enhanced Bioethanol Production and Improved Waste Management: A Review

open access: yesFood Science &Nutrition, Volume 14, Issue 2, February 2026.
The graphical abstract illustrates the conversion of food waste biomass into bioethanol through integrated pretreatment strategies. Physical (mechanical, thermal, sonication), chemical (alkali, acidic, oxidative/ROS), and biological (fungal, bacterial, enzymatic) pretreatments enhance biomass breakdown.

Unlocking the Impact of Temperature and Salinity on Greenhouse Gas Emissions From Estuarine Salt Marsh Soils

open access: yesEarth's Future, Volume 14, Issue 2, February 2026.
Abstract Salt marshes hold substantial potential for nature‐based climate solutions; yet their carbon sequestration potential is threatened by greenhouse gas (GHG) emissions under global warming and sea‐level rise (SLR). The combined effects of temperature and salinity on soil GHG emissions still remain unclear. This study integrated in situ monitoring

A Genetic System for Methanocaldococcus jannaschii: An Evolutionary Deeply Rooted Hyperthermophilic Methanarchaeon

open access: yesFrontiers in Microbiology, 2019
Phylogenetically deeply rooted methanogens belonging to the genus of Methanocaldococcus living in deep-sea hydrothermal vents derive energy exclusively from hydrogenotrophic methanogenesis, one of the oldest respiratory metabolisms on Earth.
