Paleoproterozic Icehouses and the Evolution of Oxygen Mediating Enzymes: The Case for a Late Origin of Photosystem -- II [PDF]

, 2008
Two major geological problems regarding the origin of oxygenic photosynthesis are: (1) identifying a source of oxygen predating biological oxygen production and capable of driving the evolution of oxygen tolerance, and (2) determining when oxygenic ...

Influence of Asymmetry on the Molecular and Electronic Structures of μ‐Oxo Diferric Complexes

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 2, 5 February 2026.
The 6‐methyl substituents at the pyridines (shown in red) enforce longer MNpy bonds than without them (shown in green).The asymmetric dinucleating susanH2Me2 is used for the synthesis of a μ‐oxo diferric complex. Comparison to the two symmetric complexes of susan and susan6−Me shows a strong effect on the redox potentials.

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

Food 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.

Identification of Novel Methane-, Ethane-, and Propane-Oxidizing Bacteria at Marine Hydrocarbon Seeps by Stable Isotope Probing [PDF]

, 2010
Marine hydrocarbon seeps supply oil and gas to microorganisms in sediments and overlying water. We used stable isotope probing (SIP) to identify aerobic bacteria oxidizing gaseous hydrocarbons in surface sediment from the Coal Oil Point seep field ...

Systems‐Level Optimization of Hybrid Produced Water Treatment Systems for Sustainable Oil and Gas Production: A Review of Current Technologies

Global Challenges, Volume 10, Issue 2, February 2026.
ABSTRACT Produced water (PW) is the largest and most complex waste stream generated during oil and gas production, posing significant environmental, operational, and regulatory challenges due to its high salinity, dispersed hydrocarbons, toxic organics, heavy metals, and naturally occurring radioactive materials. Although numerous studies have reviewed
