Degradation of trans-ferulic and p-coumaric acid byAcinetobacter calcoaceticus DSM 586
Biochimica et Biophysica Acta (BBA) - General Subjects, 1995 Cell suspensions of Acinetobacter calcoaceticus strain DSM 586 and DSM 590 were able to grow on benzoic, p-hydroxybenzoic and vanillic acid as sole carbon source. Testing the utilization of trans-ferulic and p-coumaric acid, we found that the sole A. calcoaceticus DSM 586 efficiently degraded the lignocellulose related monomers.

p -Coumaric acid esters from Tanacetum longifolium
Phytochemistry, 2003 Two new long chain alkyl p-coumaric acid esters (2-3) along with eicosanyl trans-p-coumarate (1) were isolated from chloroform extract of the roots of Tanacetum longifolium. The structures of new compounds were assigned as 21'-hydroxyheneicosanyl-4-hydroxy-(cis and trans) p-coumarate (2a, 2b) and 27'-hydroxy heptacosanyl-cis-p-coumarate (3) by ...

Biotransformation of p-coumaric acid by Paecilomyces variotii
Letters in Applied Microbiology, 2006To investigate the biotransformation of p-coumaric acid into p-hydroxybenzoic acid (p-HBA) by Paecilomyces variotii Bainier MTCC 6581.As a result of p-coumaric acid degradation by P. variotii, three phenolic metabolites, p-hydroxybenzaldehyde (p-HBAld), p-HBA and protocatechuic acid were formed. These phenolics were detected using TLC and HPLC.

Solvation of p-Coumaric Acid in Water
The Journal of Physical Chemistry B, 2007The photoactive yellow protein (PYP) is an important model protein for many (photoactive) signaling proteins. Key steps in the PYP photocycle are the isomerization and protonation of its chromophore, p-coumaric acid (pCA). In the ground state of the protein, this chromophore is in the trans configuration with its phenolic oxygen deprotonated.

p-Coumaric acid abatement by ozone in aqueous solution
Water Research, 1995Abstract The ozonation process of p-coumaric acid in aqueous solution is studied by identification and quantitative evaluation of intermediates and final oxidation products. In all the investigated pH range (2.0–8.0) the initial oxidation step is represented by the direct attack of ozone to the exocyclic double bond, following oxidation steps being ...

Tyrosinase inhibitory p‐Coumaric acid from Ginseng leaves
Phytotherapy Research, 1999By bioassay-guided fractionation using mushroom tyrosinase, p-coumaric acid was characterized as the principal tyrosinase inhibitor from the fresh leaves of Panax ginseng (Araliaceae). It inhibited the oxidation of L-tyrosine more strongly than that of L-3, 4-dihydroxyphenylalanine (L-DOPA) by this enzyme.

Fluorometric determination of p-coumaric acid in beer
Journal of Agricultural and Food Chemistry, 1988A new spectrofluorometric method to determine p-coumaric acid in beer has been developed. After the pH of the samples was adjusted to 2, impurities were extracted into hexane. Phenolics were then extracted into ethyl acetate, dried, and redissolved in water.
