Diverse bacteria and archaea use atmospheric CO as an energy source for long-term survival. Bacteria use [MoCu]-CO dehydrogenases (Mo-CODH) to convert atmospheric CO to carbon dioxide, transferring the obtained electrons to the aerobic respiratory chain. However, it is unknown how these enzymes oxidize CO at low concentrations and interact with the respiratory chain.

The present work emphasizes the viability of methyl ester production, characterization, and utilization of third-generation biofuel from Chlorella vulgaris microalgae. The presence of methyl oleate (CHO) in the Chlorella vulgaris methyl ester (CVME) algae signifies the existence of higher oxidation stability and prone to peroxidation. The single-stage transesterified CVME algae contains majorly (C-H) functional group trailed by (C = O), (C-O), (O-CH), (C-O-C) with the elemental compositions of 66.

Sepsis is a life-threatening condition caused by severe infection and often complicates acute respiratory distress syndrome (ARDS) and acute lung injury (ALI) due to the collapse of the oxidative and inflammatory balance induced by microbial pathogens, including lipopolysaccharides (LPS). In sepsis-related ARDS/ALI, NADPH oxidase (NOX) and toll-like receptors (TLR) in neutrophils and macrophages are key players in initiating oxidative and inflammatory imbalances. Although NOX and TLR activation has been linked to carbon monoxide (CO), the mechanism by which CO affects sepsis-related ARDS/ALI through NOX and TLR remains unknown.
