Microbial metabolism of aromatic amines. Part IV. Rapid biodegradation of aniline by Frateuria species ANA-18 and its aniline metabolism.

Cloning and functional analysis of aniline dioxygenase gene cluster, from Frateuria species ANA-18, that metabolizes aniline via an ortho-cleavage pathway of catechol.

Genes encoding an aniline dioxygenase of Frateuria sp. ANA-18, which metabolizes aniline via the ortho-cleavage pathway of catechol, were cloned and named tdn genes. The tdn genes were located on the chromosomal DNA of this bacterium and weren't clustered with catechol-degrading gene clusters. These results show that the ANA-18 aniline-degrading gene cluster is constructionally different from P...

Purification and Characterization f Two Muconate Cycloisomerase from Aniline - assimilating 1 lyateuria Species ANA - 18

Two muconate cycloisomerases (MC I and MC II, EC 5.5.1.1> were purified to homogeneity from a" anilinegrown R'ateuria sp. ANA-18. MC I and MC II were similar in molecular mass, optimal pH, and pH stability but differny ent in thermostability, and some other enzymatic properties. NH2-terminal amino acid sequences were different between the twe isozymes, indicated that these are encoded by differ...

Metabolism of aromatic amino acids and amines.

Herbicide metabolism in plants: specificity of peroxidases for aniline substrates.

Studies on the metabolism in plants (4, 5, 6, 8) aInd in soil (1, 2) of the herbicide propanil (3,4-dichloropropionanilide) have showin that the parent compound is rapidly hydrolyzed to release 3,4-dichloroaniline (DCA). In plants, the aniline moiety is recovered in several compounds including sugar and lign,in conjugates (6, i7), while in soil the major product is an azo compound identified as...

Biodegradation of polycyclic aromatic hydrocarbons by Pseudomonas species

Biodegradation of polycyclic aromatic hydrocarbons, toxic compounds widely distributed in the environment by bacteria, is a cheap and safe cleaning up method. The present study attempts to isolate and characterize dioxygenase-producing bacteria which are able to degrade phenanthrene and pyrene from refinery soils. It also aims to assess in vitro biodegradation. To do so, two contaminated soil s...
