Catechol is used in many industries. It can be removed from wastewater by various methods but biological processes are the most superior and commonly used technology. The SCR is a modified form of SBR used to degrade catechol. The objective of this study was to investigate the performance of SCR for biodegradation and mineralization of catechol under various inlet concentrations (630-1500 mg/L)...

In this study, the electrochemical mechanism of catechol in presence and absence of nitrite ion, is investigated in phosphate buffer medium (pH=7) using platinum electrode through cyclic voltammetry method in various scan rates. Electrochemical oxidation of catechol showed how quinone has changed to o-benzoquinone and also how o-benzoquinone has reacted with nitrite ion and potential scan rate ...

The atmospheric aerosol assisted plasma polymerization of 4-vinyl-catechol allows the facile deposition robust redox active catechol-rich films with promising properties as organic cathode materials for lithium ion battery.

The authors report the synthesis of some bioactive organic compounds which could be pharmacological interest using Dioscorea praehensilis tyrosinase immobilized on calcium-alginate beads. enzymatic these involved pyruvic acid as a source carbonyl groups, ammonia and catechol. Catechol was used substrate parent compound that supplied aromatic ring carbons for reactions. structures novel synthesi...

the electrochemical oxidation and determination of tryptophan (trp) and glutathione (gsh) in the presence of catechol as a homogeneous redox in the aqueous medium were investigated at the surface of a carbon paste electrode modified with multi-walled carbon nanotube (mwcnt-cpe) using cyclic voltammetry (cv), double step potential chronoamperometry and differential pulse voltammetry (dpv) techni...

in order to better understand how to prevent enzymatic greenning, it is important to understand  kinetic properties of polyphenol oxidase.  we investigated the effect of sds on the rate of catechol oxidation by small cherry tomato partial purified ppo. ppo activity increased with increasing sds concentration. the most effective concentration of sds was 0.8, 1 and 1.25 mm in according to ph and ...

Catechol (benzenediol) is present in plant-derived products, such as vegetables, fruits, coffee, tea, wine, areca nut and cigarette smoke. Because platelet dysfunction is a risk factor of cardiovascular diseases, including stroke, atherosclerosis and myocardial infarction, the purpose of this study was to evaluate the anti-platelet and anti-inflammatory effect of catechol and its mechanisms. Th...

Earlier study suggested that 3,4-dihydroxytamoxifen (tam catechol), a tamoxifen metabolite, is proximate to the reactive intermediate that binds covalently to proteins and possibly to DNA (). The current study demonstrates that rat and human hepatic cytochrome P-450s (CYPs) catalyze tam catechol formation from tamoxifen (tam), 3-hydroxy-tam (Droloxifene), and 4-hydroxy-tam (4-OH-tam). Higher le...

Phytochemicals are natural dietary constituents of fruits and vegetables. Some of these phytochemicals are known to affect estrogen-metabolizing enzymes. In breast tissue, estradiol can be metabolized to the catechol estrogens 2- and 4-hydroxyestradiol (2-OHE(2) and 4-OHE(2)). Catechol estrogens are suspected carcinogens potentially involved in the etiology of breast cancer. Catechol-O-methyltr...

Benzoic acid metabolism was studied in Azotobacter vinelandii. 14 A radioactive intermediate of C-benzoic acid metabolism was discovered. Preliminary evidence suggests that this intermediate may be 2 ,-hydroxybenzoate but positive identification was not achieved, values for several hydroxybenzoates and catechol on paper chromato­ graphy in various solvent systems are given. The oxygenase, metap...
