RB-TnSeq elucidates dicarboxylic-acid-specific catabolism in β-proteobacteria for improved plastic monomer upcycling [PDF]

Applied and Environmental Microbiology
Dicarboxylic acids are key components of many polymers and plastics, making them a target for both engineered microbial degradation and sustainable bioproduction. In this study, we generated a comprehensive data set of functional evidence for the genetic

Fully exposed Ptn cluster catalysts enable cascade oxidation of polyol to dicarboxylic acid [PDF]

Nature Communications
The polyol oxidation to dicarboxylic acid, a crucial value-accretive reaction, is still challenging due to the paradoxical relationship between efficient activation of C-H bond and rapid desorption of carboxylic acid.

Four- and Five-Carbon Dicarboxylic Acids Present in Secondary Organic Aerosol Produced from Anthropogenic and Biogenic Volatile Organic Compounds

Atmosphere, 2021
To better understand precursors of dicarboxylic acids in ambient secondary organic aerosol (SOA), we studied C4–C9 dicarboxylic acids present in SOA formed from the oxidation of toluene, naphthalene, α-pinene, and isoprene.

Identification of isomeric unsaturated medium-chain dicarboxylic acids in human urine.

Journal of Lipid Research, 1989
Dicarboxylic aciduria caused by enhanced or inhibited fatty acid metabolism is usually described as increased urinary excretion of saturated medium-chain dicarboxylic acids, such as adipic, suberic, and sebacic acids.

Molecular characteristics and stable carbon isotope compositions of dicarboxylic acids and related compounds in wintertime aerosols of Northwest China

Scientific Reports, 2022
Dicarboxylic acids are one of the important water-soluble organic compounds in atmospheric aerosols, causing adverse effects to both climate and human health. More attention has therefore been paid to organic acids in aerosols.
