Phthalates (PAEs) are the di-alkyl or di-alkyl-aryl esters of phthalic acid (PA), the main precursor of phthalate. Phthalic acid consists of two carboxylic groups at the ortho

Phthalate acid ester hydrolases are of promise for the microbial degradation of phthalate acid ester plasticizers, however, only a small number of PAE hydrolases have been characterized.

The reason is the further reactions between phthalic acid and NH 3-containing species with the increase of temperature, which resulted in the conversion of phthalic acid to other compounds. It can be confirmed by the analysis results of decomposition products obtained at higher temperature (for example, 300 °C), which will be discussed in

The major part of the absorbed formic acid is metabolized in the liver, but partially also in the intestinal mucosa, lungs, kidneys and spleen. Formic acid is oxidized in relation to folate and according to a catalase-peroxidative mechanism.

What is plasticizer phthalate?
Plasticizer phthalate is a pollutant. Its teratogenic or carcinogenic effects on human. Phytotoxic effects of phthalate and its transmission through food chain. Abatement of phthalate via bioremediation. Microbe-mediated soil-phthalate bioaugmentation approaches.
Is phthalic acid a benzene ring?
Phthalic acid consists of two carboxylic groups at the ortho position of a benzene ring. Commonly in the generic formula of phthalate, there are linear or branched side chains of alkyl groups having 1–28 carbon atoms. PAEs were first introduced in the 1920s as pest repellents and used to be infused with Polyvinyl chloride (PVC) brushes.
Are phthalate acid esters a good treatment for microbial degradation?
Phthalate acid esters (PAEs), a group of xenobiotic compounds used extensively as plasticizers, have attracted increasing concern for adverse effects to human health and the environment. Microbial degradation relying on PAE hydrolases is a promising treatment. However, only a limited number of PAE hydrolases were characterized to date.
Which enzyme converts di-alkyl phthalate into phthalic acid?
In the first reaction, the enzyme di-alkyl phthalate hydrolase converts the di-alkyl phthalates to their monoalkyl ester forms (hydrolyzation step I) which is then converted into phthalic acid (PA) by the activity of the enzyme monoalkyl phthalate hydrolase (hydrolyzation step II) (Fan et al., 2018; Tang et al., 2016; Wu et al., 2010a).
How many phthalic acid esters are in food simulants?

I., Sabra, R., Jurdi, M. & Taleb, R. I. Assessment of toxic metals and phthalates in children’s toys and clays. Arch. Environ. Con. Tox. 65, 368–381 (2013).
How many binding residues are present in phthalate hydrolase mphg?
Molecular docking and molecular dynamics simulation analysis has revealed the occurrence of three binding residues viz. R173, R126 & F54 and a catalytic triad S125– H291-D259 in the active site of the enzyme phthalate hydrolase MphG.
