Manganese‐oxidizing bacteria mediate the degradation of 17α‐ethinylestradiol
Manganese (II) and manganese-oxidizing bacteria were used as an efficient biological system for the degradation of the xenoestrogen 17α-ethinylestradiol (EE2) at trace concentrations. Mn(2+)-derived higher oxidation states of Mn (Mn(3+), Mn(4+)) by Mn(2+)-oxidizing bacteria mediate the oxidative cleavage of the polycyclic target compound EE2. The presence of manganese (II) was found to be essen...
متن کاملComparing Methods of 17α-ethinylestradiol (EE2) Determination in Surface Water
We compared methods of determination of 17α-ethinyloestradiol (EE2) in surface water in Kielce, Poland. EE2 plays a role as a contraception agent and it is commonly used as an active agent in contraception pills. During studies three methods of EE2 determination were checked: TLC, HPLC, and ELISA assay. Samples of contaminated water were taken from eight points on four rivers crossing Kielce ci...
متن کاملCatalytic oxidative degradation of 17α-ethinylestradiol by FeIII-TAML/H2O2: estrogenicities of the products of partial, and extensive oxidation.
The oxidative degradation of the oral contraceptive 17α-ethinylestradiol (EE(2)) in water by a new advanced catalytic oxidation process was investigated. The oxidant employed was hydrogen peroxide in aqueous solution and the catalyst was the iron tetra-amido macrocyclic ligand (Fe(III)-TAML) complex that has been designated Na[Fe(H(2)O)(B*)] (Fe(III)-B*). EE(2) (10 μM) was oxidised rapidly by t...
متن کاملComparison of factors influencing trichloroethylene degradation by toluene-oxidizing bacteria.
The degradation of trichloroethylene (TCE) by toluene-oxidizing bacteria has been extensively studied, and yet the influence of environmental conditions and physiological characteristics of individual strains has received little attention. To consider these effects, the levels of TCE degradation by strains distinguishable on the basis of toluene and nitrate metabolism were compared under aerobi...
متن کاملSurvey of microbial oxygenases: trichloroethylene degradation by propane-oxidizing bacteria.
Microorganisms that biosynthesize broad-specificity oxygenases to initiate metabolism of linear and branched-chain alkanes, nitroalkanes, cyclic ketones, alkenoic acids, and chromenes were surveyed for the ability to biodegrade trichloroethylene (TCE). The results indicated that TCE oxidation is not a common property of broad-specificity microbial oxygenases. Bacteria that contained nitropropan...
