4-Chlorophenol degradation by a bacterial consortium: development of a granular activated carbon bio®lm reactor
A bacterial consortium that can degrade chloroand nitrophenols has been isolated from the rhizosphere of Phragmitis communis. Degradation of 4-chlorophenol (4-CP) by a consortium attached to granular activated carbon (GAC) in a bio®lm reactor was evaluated during both open and closed modes of operation. During the operation of the bio®lm reactor, 4-CP was not detected in the column euent, bein...
متن کاملComparison of Different Advanced Oxidation Processes for Degrading 4-Chlorophenol
The removal efficiency of 4-chlorophenol with different advanced oxidation processes have been studied. Oxidation experiments were carried out using two 4-chlorophenol concentrations: 100 mg L and 250 mg L and UV generated from a KrCl excilamp with (molar ratio H2O2: 4-chlorophenol = 25:1) and without H2O2, and, with Fenton process (molar ratio H2O2:4chlorophenol of 25:1 and Fe concentration of...
متن کاملBacterial hydrocarbon-degrading consortium from Antarctic soils.
Removal of contaminants from polluted environments could be improved by taking advantage of the catabolic capacity of some microorganisms in a process called bioremediation. Nowadays, the use of microbial associations (also called microbial consortia) is gaining attention, because they seem to have a wider degradation spectrum than that exhibited by isolated strains. M10 is a bacterial consorti...
متن کاملImproved technique for identification and enumeration of methanogenic bacterial colonies on roll tubes by epifluorescence microscopy.
Methanogenic fluorescent colonies can be clearly identified on roll tubes by using an epifluorescence microscope equipped with a x 2 objective. Methanogenic and nonmethanogenic colonies could be counted in roll tubes prepared from methanogenic enrichment cultures. Late-developing colonies appearing after 25 days of incubation were mainly methanogenic.
متن کاملMembrane biofouling mechanism in an aerobic granular reactor degrading 4-chlorophenol.
The membrane fouling of an aerobic granular reactor coupled with a submerged membrane in a sequencing batch reactor (SBR) was evaluated. The fouling analysis was performed by applying microscopy techniques to determine the morphology and structure of the fouling layer on a polyvinylidene fluoride membrane. It was found that the main cause of fouling was the polysaccharide adsorption on the memb...
