Bioelectrochemical upgrading of anaerobic digester biogas under thermophilic conditions

Renewable Energy and Environmental Sustainability, 2023
Bioelectrochemical systems (BESs) can be integrated in situ into anaerobic digesters for increasing methane (CH4) content of biogas. Using BES ex situ for improving biogas quality has recently been gaining attention.

Effect of midday pasteurizer washing on thermoduric organisms and their progression through Cheddar cheese manufacturing and ripening

Journal of Dairy Science, 2022
: Thermoduric bacteria are known to affect the quality of Cheddar cheese, with manifested defects including slits, weak body, and blowing. Thermoduric bacteria are likely to increase in numbers during cheese-making, as in-process conditions are conducive

Aquatic biota in hot water: thermal gradients in rheocrene hot spring discharges as analogues for the effects of climate warming

Knowledge and Management of Aquatic Ecosystems, 2020
Hot springs are characterised by water temperatures above 36.7 °C. Temperature decreases with distance in flow away from spring vents; this natural gradient provides a unique opportunity to investigate the influence of water temperature on aquatic biota.

CO2-Induced Transcriptional Reorganization: Molecular Basis of Capnophillic Lactic Fermentation in Thermotoga neapolitana

Frontiers in Microbiology, 2020
Capnophilic lactic fermentation (CLF) is a novel anaplerotic pathway able to convert sugars to lactic acid (LA) and hydrogen using CO2 as carbon enhancer in the hyperthermophilic bacterium Thermotoga neapolitana.

Acetate Production by Moorella thermoacetica via Syngas Fermentation: Effect of Yeast Extract and Syngas Composition

Fermentation, 2023
Gasifiers produce a gaseous mixture of CO/CO2/H2, also known as synthesis gas (syngas), containing varying compositions and ratios depending on the lignocellulose material types, gasifier design, and gasification conditions. Different physicochemical and
