Phenylobacterium immobile gen. nov., sp. nov., a Gram-Negative Bacterium That Degrades the Herbicide Chloridazon
TLDR
Bacteria which utilize the xenobiotic compounds chloridazon, antipyrin, and pyramidon as sole carbon sources were isolated from various soil samples and characterized as a new genus, Phenylobacterium, with a single species,phenylobacteria immobile, which is a serologically uniform group of organisms, which are harmless to rats and rabbits.

Degradation of 2,4,6-trichlorophenol by Azotobacter sp. strain GP1
TLDR
Induction studies, including treatment of the cells with chloramphenicol prior to TCP or phenol addition, revealed that TCP induced TCP degradation but not phenol degradation and that phenol induced only its own utilization. Expand
Purification and characterization of 6-chlorohydroxyquinol 1,2-dioxygenase from Streptomyces rochei 303: comparison with an analogous enzyme from Azotobacter sp. strain GP1
TLDR
The enzyme which cleaves the benzene ring of 6-chlorohydroxyquinol was purified to apparent homogeneity from an extract of 2,4,6-trichlorophenol-grown cells of Streptomyces rochei 303 and appeared to be a dimer of two identical 31-kDa subunits. Expand
Metabolism of 4-chlorophenol by Azotobacter sp. GP1: structure of the meta cleavage product of 4-chlorocatechol.
A mutant strain of Azotobacter sp. GP1 converted 4-chlorophenol to 4-chlorocatechol under cometabolic conditions. Under the same conditions the wild-type strain accumulated a yellow compound, whichExpand
Purification and characterization of 2,4,6-trichlorophenol-4-monooxygenase, a dehalogenating enzyme from Azotobacter sp. strain GP1
The enzyme which catalyzes the dehalogenation of 2,4,6-trichlorophenol (TCP) was purified to apparent homogeneity from an extract of TCP-induced cells of Azotobacter sp. strain GP1. The initial stepExpand
Purification and Characterization of 6-Chlorohydroxyquinol 1 , 2-Dioxygenase from Streptomyces rochei 303 : Comparison with an Analogous Enzyme from Azotobacter sp . Strain GP 1
The enzyme which cleaves the benzene ring of 6-chlorohydroxyquinol was purified to apparent homogeneity from an extract of 2,4,6-trichlorophenol-grown cells of Streptomyces rochei 303. Like theExpand
Purification and properties of pyrazon dioxygenase from pyrazon-degrading bacteria.
TLDR
Chromatography on DEAE-cellulose and gel filtration on Sephadex revealed that pyrazon dioxygenase frompyrazon-degrading bacteria consists of three different enzyme components, and a hypothetical scheme for the cooperation of the three components is proposed. Expand
Enzymatic and chemical preparation of 5-amino-4-chloro-2-(2,3-dihydroxyphen-1-yl)-3(2H)-pyridazinone.
TLDR
A hypothetical intermediate of the microbial degradation of pyrazon was prepared by enzymatic and chemical treatment of 5-amino-4-chloro-2(2,3-dihydroxy-cyclohexa-4,6-dien-1-yl)-pyridazinone and the properties of the metabolite are described. Expand
Serological studies on chloridazon-degrading bacteria.
TLDR
Differences in the extent of agglutination reactions and antibody titres among chloridaz-degrading bacterial strains together with cross-adsorption xperiments suggest a rough classification of chloridazon-degRading bacteria into two subgroups. Expand
