Article Abstract
The use of exogenous carbon monoxide releasing molecules (CORMs) provides promise for clinical application; however, the hazard potential of CORMs in vivo remains poorly understood. The developmental toxicity of CORM-3 was investigated by exposure to concentrations ranging from 6.25 to 400 μmol/L during 4-144 h post fertilization. Toxicity endpoints of mortality, spontaneous movement, heart rate, hatching rate, malformation, body length, and larval behavior were measured. CORM-3 disrupted the progression of zebrafish larval development at concentrations exceeding 50 μmol/L, resulting in embryonic developmental toxicity.

For the first time, long-wavelength red emission carbon dots (R-CDs) were prepared as ratiometric fluorescent and colorimetric dual-mode sensors for detecting ClO using a simple one-step hydrothermal method. R-CDs exhibited intrinsic red fluorescence at 587 nm. Upon interaction with ClO, a new and enhanced green fluorescence at 535 nm was observed, which was attributed to resulting from the oxidation of surface hydroxyl (-OH) groups to carbonyl (CO) groups.

Volatile organic compounds (VOCs) are carbon-based chemicals characterized by high vapor pressure and low boiling points under standard temperature and pressure conditions. VOCs are categorized as exogenous or endogenous, depending on their source. Endogenous VOCs are metabolic byproducts eliminated via respiration.

Different precursors of volatile sulfur compounds (VSCs) are present in fermented beverages, such as wine and beer. Carbon-sulfur (CS) lyases are enzymes that play a crucial role in releasing aromas from these varietal thiol precursors. These enzymes are expressed by various organisms, including yeasts and bacteria, involved in fermentation processes during brewing and winemaking.

SC05-UT is an anaerobic, heterogenous microbial enrichment culture that reduces chloroform to dichloromethane through reductive dechlorination, which it further mineralizes to carbon dioxide. This dichloromethane mineralization yields electron equivalents that are used to reduce chloroform without the addition of exogenous electron donor. By studying this self-feeding chloroform-amended culture and a dichloromethane-amended enrichment subculture (named DCME), we previously found the genomic potential to perform both biodegradation steps in two distinct strains: SAD and Dehalobacter alkaniphilus DAD.

Dissolved carbon is a crucial component of freshwater ecosystems and plays an important role in the Earth's carbon cycle. This paper delivers a groundbreaking exploration of dissolved carbon (DOC and DIC) variations spanning 12 years in a eutrophic lake where nutrient levels are gradually declining to reveal their spatial and temporal distribution patterns and the key drivers behind this variation. Our findings indicate that both DIC and DOC concentrations in Lake Chaohu exhibit a westward spatial gradient, with an overall upward trend in DIC levels from 2012 to 2023, contrasting with a downward trend in DOC.
