Also, further cleavage of catechol by catechol 1,2 dioxygenase or catechol 2,3 dioxygenase was detected by formation of cis,cis-muconic acid at 260nm or muconic
acid semialdehyde at 375 nm respectively.
High concentrations of muconic
acid - a degradation product of benzene (a volatile, toxic and carcinogenic compound) - were detected in the urine of 29 pregnant women who participated in the pilot study.

acid biomarker and platelet count in a sample of subjects with benzene exposure," Clinical and Applied Thrombosis/Hemostasis, vol.
Catechol can later be oxidized further to muconic
acid or 2-hydroxymuconic semialdehyde  which can finally be degraded to yield organic acids that are used by microorganisms for cell synthesis and energy production .
The presence of Catechol-1,2-dioxygenase (C12D) or Catechol-2,3-dioxygenase (C23D) was detected by the formation of products cis-cis muconic
acid and 2-hydroxymuconic semialdehyde (2-HMS) at 260 nm and 375 nm, respectively (Santos and Linardi, 2004).
[USPRwire, Fri Sep 04 2015] Fast Market Research announces the availability of Technavio's new report "Global Muconic
Acid Market 2015-2019" on their comprehensive research portal.
Myriant is also targeting acrylic acid, as well as lactic acid, muconic
acid, and fumaric acid.
1999 Vinylidene chloride CDC 2009 (1,1-dichloroethene) Abbreviations: Hb, hemoglobin; HEMA, 2-hydroxyethyl mercapturic acid; MA, muconic
acid; NA, not applicable; PFOA, perfluorooctanoic acid.
Building on our success with bio-succinic acid, Myriant is continuing to expand its product portfolio, including the development and scale-up of new bio-based chemicals like acrylic acid and muconic
acid, basic building blocks used to make many every day products.
Dicarboxylic, maleic, and muconic
acids are important compounds as a result of ring opening of aromatic intermediates.
(26) Draths, which was sold to Amyris, also described an ethylene Diels Alder route with muconic
acid to terephthalic acid.
It is well known that the ozone oxidization treatment cleaves the aromatic ring of lignin and generates the muconic
acid derivative, which has the muconic
acid residue with carboxyl groups on both ends of the conjugate double bond.
