Production of phenylacetic acid by anaerobes.
We tested 388 strains of anaerobes from 17 genera for the production of phenylacetic acid. The compound was found in only two genera (Bacteroides and Clostridium) but not within all the species of these genera.
متن کاملFormation of 6-aminopenicillanic acid, penicillins, and penicillin acylase by various fungi.
Several penicillin-producing fungi were examined for ability to produce 6-aminopenicillanic acid (6-APA) and penicillin acylase. 6-APA was found in corn steep liquor fermentations of Trichophyton mentagrophytes, Aspergillus ochraceous, and three strains of Penicillium sp. 6-APA was not detected in fermentations of Epidermophyton floccosum although penicillins were produced. 6-APA formed a large...
متن کاملConformational preferences of 3,4-dihydroxyphenylacetic acid (DOPAC).
The conformational space of 3,4-dihydroxyphenylacetic acid (DOPAC), an important dopamine metabolite, has been investigated by quantum chemical methods (B3LYP and MP2, with the 6-311++G(d,p) basis set) and matrix-isolation infrared spectroscopy. Detailed analysis of the calculated potential energy surfaces of the molecule led to identification of thirteen unique conformers, all of them showing ...
متن کاملThe bacterial oxidation of phenylacetic acid.
The bacterial oxidation of aromatic compounds closely related in chemical structure may proceed by different pathways. Thus, while the main features of the breakdown of mandelic acid are established, those of phenylacetate are not, except insofar as it is known to follow a different route (Stanier, 1950). The divergencies may possibly indicate a difference in the mode of ring fission; and since...
متن کاملAntioxidant phenylacetic acid derivatives from the seeds of Ilex aquifolium.
Reversed-phase preparative HPLC analysis of the methanol extract of the seeds of Ilex aquifolium afforded two antioxidant phenylacetic acid derivatives, 2,4-dihydroxyphenylacetic acid (1) and 2,4-dihydroxyphenylacetic acid methyl ester (2). The structures were determined by spectroscopic methods. In the DPPH assay for antioxidant activity, the IC(50) values of 1 and 2 were 1.50 x 10(-3) and 2.5...
