Summary: Archaeal membrane lipids, specifically the GDGTs, can be used to reconstruct ancient temperatures and provide insights into the ecology and evolution of marine ammonia-oxidizing archaea (AOA). The study identified thermal and nonthermal behaviors of GDGTs, which can be used as indicators of environmental temperature. The distribution of GDGTs in AOA cultures and shallow water samples followed a temperature-dependent trend, while deep water samples showed a nonthermal behavior. Statistical analysis revealed long-term trends in GDGT-2/GDGT-3 ratios, suggesting a suppression of deep water marine AOA during greenhouse climates in the Mesozoic and early Cenozoic periods.

Summary: This article presents the development of a humidity sensor based on bacterial nanocellulose membrane (BNC) produced from Komagataeibacter xylinus. The BNC has a porous surface that can absorb water, thereby changing the mechanical and electrical properties of the membrane. The capacitance of the BNC was measured at different temperatures (from 30 degrees to 100 degrees) and relative humidities (from 30% to 100%). Chronoamperometry was used for reproducibility testing, and the results showed a linear and more precise variation for relative humidity over 50% and a temperature of 30 degrees. The measurements revealed a combined sensitivity of -4.13 nF/degrees C to temperature, and +492 nF/(%RH) and +66.8 nA/(%RH) to relative humidity.

Summary: In recent years, research has shown that the addition of conductive materials can significantly improve anaerobic digestion and methane production. However, there are still questions regarding the mechanism and impact of material properties on methanogenic pathways. A systematic review and statistical analysis of recent studies found that the use of conductive materials is associated with changes in the microbial community and that millimeter-scale materials may be more effective in increasing methane production. Overall, the use of conductive materials shows promise in improving anaerobic digestion and methane production.

Summary: This study evaluated the adsorptive process for the removal of water-soluble organic compounds (WSO), specifically naphthenic acids, in synthetic and real oilfield produced water (OPW). The results showed that WSO adsorption capacity was higher at lower pH values. The adsorption kinetics followed the pseudo-second order model, while the equilibrium parameters were represented by the isothermal BET model. Desorption followed the second-order model, with 0.3 M and 0.1 M sodium hydroxide solution demonstrating the highest desorption efficiency in synthetic and real systems, respectively. The adsorbent was effective for up to three consecutive cycles without significant loss of efficiency, and the treated effluent met legal parameters for offshore disposal, enhancing its industrial application.
