Decolourization of 4-Chloro-2-Nitrophenol by a Soil Bacterium, Bacillus subtilis RKJ 700
A 4-Chloro-2-nitrophenol (4C2NP) decolourizing strain RKJ 700 was isolated from soil collected from a pesticide contaminated site of India and identified as Bacillus subtilis on the basis of the 16S rRNA gene sequence analysis. Bacillus subtilis RKJ 700 decolourized 4C2NP up to concentration of 1.5 mM in the presence of additional carbon source. The degradation pathway of 4C2NP was studied and ...
متن کاملMetabolism of 2-Chloro-4-Nitrophenol in a Gram Negative Bacterium, Burkholderia sp. RKJ 800
A 2-chloro-4-nitrophenol (2C4NP) degrading bacterial strain designated as RKJ 800 was isolated from a pesticide contaminated site of India by enrichment method and utilized 2C4NP as sole source of carbon and energy. The stoichiometric amounts of nitrite and chloride ions were detected during the degradation of 2C4NP. On the basis of thin layer chromatography, high performance liquid chromatogra...
متن کاملArthrobacter nitrophenolicus sp. nov. a new 2-chloro-4-nitrophenol degrading bacterium isolated from contaminated soil
Strain SJConT, a 2-chloro-4-nitrophenol (2C4NP) degrading bacterium, was isolated from soil collected from a pesticide-contaminated site in Punjab, India. The strain, which stained Gram positive, displayed a rod-coccus life cycle, and possessed a type A3α peptidoglycan (L-Lys-L-Ala3), MK-9(H2) as the major menaquinone, anteiso-C15 and iso-C15:0 as the major cellular fatty acids, and diphosphati...
متن کاملAdsorption of 4-Chloro-2-nitrophenol onto Nano-ZnO
Nano-ZnO was employed for the adsorption of 4C2NP from aqueous solutions in batch equilibriumexperiments to investigate its adsorption properties. The quantity of 4C2NP adsorbed onto nano- ZnOsurface was measured by UV-Vis spectrophotometer. The effects of contact time, adsorbent dose, pH, andinitial concentration of 4C2NP were investigated. The adsorption found to be strongly influenced by all...
متن کاملMetabolism of 4-chloro-2-nitrophenol in a Gram-positive bacterium, Exiguobacterium sp. PMA
BACKGROUND Chloronitrophenols (CNPs) are widely used in the synthesis of dyes, drugs and pesticides, and constitute a major group of environmental pollutants. 4-Chloro-2-nitrophenol (4C2NP) is an isomer of CNPs that has been detected in various industrial effluents. A number of physicochemical methods have been used for treatment of wastewater containing 4C2NP. These methods are not as effectiv...
