Summary: Microbial conversion of CO2 and CO into chemicals is a promising approach to reduce greenhouse gas emissions and create a more circular economy. However, the limited number of model microorganisms and the small profit margin of the synthesized products are still restricting the biotechnological valorization of CO2 and CO. This study explores the genetic potential of microbial conversion of CO2 and CO into ectoines, aiming to broaden bioconversion platforms and the variety of products. A literature review and gene mining were conducted to identify halophilic microbes capable of using CO2 and CO as a carbon source and producing ectoines. The identified microbes provide a basis for the development of cost-effective and sustainable valorization chains of CO2 and CO in different industrial scenarios.

Summary: Reactive capture of CO2 (RCC) involves integrating CO2 capture with the conversion of captured CO2 into a product. This method has the potential to save significant energy compared to traditional CO2 capture and release processes as it does not include a step for thermal release of CO2. The Perspective highlights prior contributions to CO2 capture chemistry, thermal RCC, and electrochemically driven RCC, focusing on opportunities and challenges for future development. RCC requires a multidisciplinary approach, bridging industry, chemistry, chemical engineering, and advanced manufacturing.

Summary: Clear-sky CO2 forcing varies significantly globally, primarily influenced by surface temperature, stratospheric temperature, and column relative humidity. The difference in forcing between regions is mainly due to the surface-stratosphere temperature contrast. In tropical and midlatitude regions, the presence of water vapor modulates the forcing by affecting atmospheric emissions.

Summary: This study assesses the predictive capability of the mathematical model RUMINANT for methane emissions from livestock. The model performs well in predicting dry matter intake but underestimates methane emissions. This discrepancy may be due to the anti-methanogenic factors of Leucaena that are not considered by the model.

Summary: The implicit interaction between electroactive microbes and solid electrodes plays an important role in bioelectrochemical systems, especially in the development of microbial fuel cells (MFCs) for converting low-value waste streams into bioelectricity. The metabolism of interacted microbes with electrodes is influenced by the microenvironment at the electrodes, which in turn affects the current response. This phenomenon has been extensively studied and utilized for selectively detecting heavy metal ions (HMIs) using MFCs.

Summary: Low power output in biophotovoltaics (BPV) due to poor anode kinetics is minimized by modifying the anode with rGO-Zeolite, which improves electrochemical redox reactions. Horizontal Torch separator-based urine fed BPV with rGO-Zeolite anodes achieve higher power production and N/P-recovery compared to bare graphite anodes. The modified anode results in a power output of 146.88 mW/m2, redox current of 18.9 mA, and significant recovery of Phosphorous and NH4+-N.

Summary: Nitrogen is crucial for life and food production, but the loss of unused nitrogen in wastewater, air, freshwater, and oceans has led to nitrogen pollution, impacting the environment and causing eutrophication, climate change, biodiversity loss, and ozone depletion. It also affects human health by causing cardio respiratory issues. Anthropogenic activities like food processing, fertilizer production, and mining have disrupted the global nitrogen cycle. Autotrophic ammonia-oxidizing microbial communities, such as AOA, AOB, and AnAOB, are widely used to remove nitrogen. New strategies, such as Anammox, Feammox, and Comammox, are being developed to reduce carbon footprint and improve nitrogen removal efficiency. This review explores the applications of autotrophic ammonia oxidizers in agriculture, wastewater treatment plants, and engineered ecosystems, as well as the stress impacts on these organisms.
