The degrading reaction of LZP08X accorded with Monod first-order equation. When the strain was cultured in the medium containing 400mg/L phenol,the degradation rate reached 99% in 12 hours,and the biodegradation rate constant and half lifes were 0.39 and 1.78h,respectively.
Using the quadratic regression model,the optimum concentrations were determined: temperature 28℃,pH value 7.0,concentration 1 500 mg/L,medium volume 100 mL and inoculum amount 10%,respectively,the predicted yield of the methamidophos degrading rate was 73.65%.
coli JM109 (containing plasmid pT7) degrading 1,2,4-TCB, the partial intermediate products were inspected and surveyed as 2,3,5-trichloromuconate, 2,5-dichloro- carboxymethylenebut-2-en-4-olide, and 2,5-dichloro-4-oxohex-2-enedioate respectively, adopting gas chromatography-mass spectrometry (GC-MS) technique.
The photocatalytic degradation of aniline on the composite films was carried out in a TiO2/UV system.
The photocatalytic degradation of methyl orange (MO) in aqueous solution under 365 nm irradiation on TiO2 and Ag/TiO2 thin films was investigated.
The thermo-oxidative degradation of the films is studied by thermogravimetric analysis (TGA).
It was found that the degradation of sodium sulfite, sodium bisulfite or sodium pyrosulfite obeyed pseudo zero-order kinetics in the buffer solutions.
The photocatalytic degradation of phenol showed that under visible light (λ >amp;gt; 400 nm) irradiation, the chlorine-doped TiO2 calcined at 300°C displayed the best performance, the degradation ratio of phenol was 42.5% after 120 min.
After degrading the PCL cores of the two kinds of nanospheres by lipase, the corresponding crosslinked poly(methyl acrylic acid) hollow spheres and crosslinked poly(vinyl alcohol) hollow spheres were obtained.
The fast algorithm presented in this paper improves the speed of the image reconstructing by approximately 32 times without degrading the reconstructed image quality.
It has been proven that they are both highly-efficient pyrene degrading bacteria and both Bacillus sp..
The effecting factors during degradation and the degrading mechanism were studied.
The aim of the present work was to know the location of the genes for degrading 1,2,4-trichlorobenzen.
Methanosarcina barkeri, had some acid resistance and could still degrade methanol at pH 5.0.
Granular sludge of the system could protect the methanogenic bacteria within its body against the impact of the acidic environment and make them degrade methanol at pH 4.5.
The results showed that to degrade 50 mL of 4-aminophenol whose concentration was 500 mg/L, the optimal conditions were: volume of H2O2 = 3 mL, temperature = 40-60°C and pH = 9-10.
The microorganisms inoculated can probably degrade the phytotoxins present in soils, thereby favoring plant development.
As follows from the comparison of the degrading and antioxidative effects, measurement of the antioxidant activity can be used in screening of fungi for the ability to degrade lignocellulose substrates.
