Design and performance of a trickling air biofilter for chlorobenzene and o-dichlorobenzene vapors.
From contaminated industrial sludge, two stable multistrain microbial enrichments (consortia) that were capable of rapidly utilizing chlorobenzene and o-dichlorobenzene, respectively, were obtained. These consortia were characterized as to their species composition, tolerance range, and activity maxima in order to establish and maintain the required operational parameters during their use in bi...
متن کاملThe broad substrate chlorobenzene dioxygenase and cis-chlorobenzene dihydrodiol dehydrogenase of Pseudomonas sp. strain P51 are linked evolutionarily to the enzymes for benzene and toluene degradation.
The chlorobenzene degradation pathway of Pseudomonas sp. strain P51 is an evolutionary novelty. The first enzymes of the pathway, the chlorobenzene dioxygenase and the cis-chlorobenzene dihydrodiol dehydrogenase, are encoded on a plasmid-located transposon Tn5280. Chlorobenzene dioxygenase is a four-protein complex, formed by the gene products of tcbAa for the large subunit of the terminal oxyg...

2. o-Dichlorobenzene also gives rise to 3:4dichlorophenylmercapturic acid as a minor metabolite (5% of the dose). 3. p-Dichlorobenzene (0.5 g./kg.) is mainly oxidized to 2:5-dichlorophenol which is excreted conjugated. 2:5-Dichloroquinol is also formed (about 6% of the dose) but in contrast with o-dichlorobenzene no mercapturic acid or dichlorocatechol is formed. 4. The excretion ofthe metaboli...
متن کاملDegradation of 1,4-dichlorobenzene by a Pseudomonas sp.
A Pseudomonas species able to degrade p-dichlorobenzene as the sole source of carbon and energy was isolated by selective enrichment from activated sludge. The organism also grew well on chlorobenzene and benzene. Washed cells released chloride in stoichiometric amounts from o-, m-, and p-dichlorobenzene, 2,5-dichlorophenol, 4-chlorophenol, 3-chlorocatechol, 4-chlorocatechol, and 3,6-dichloroca...
متن کاملDimethyl 4,5-dichlorobenzene-1,2-dicarboxylate
In the title compound, C(10)H(8)Cl(2)O(4), the two Cl atoms and one of the meth-oxy-carbonyl groups are almost coplanar [maxi-mum derivation = 0.035 (2) Å] with the benzene plane, and the other meth-oxy-carbonyl group exhibits an almost orthogonal disposition relative to the benzene plane, with a dihedral angle of 84.82 (3)° between the planes. In the crystal, the molecules are connected into a...
