Different types of dienelactone hydrolase in 4-fluorobenzoate-utilizing bacteria.
Of various benzoate-utilizing bacteria tested, Alcaligenes eutrophus 335, A. eutrophus H16, A. eutrophus JMP222, A. eutrophus JMP134, Alcaligenes strain A7, and Pseudomonas cepacia were able to grow with 4-fluorobenzoate as the sole source of carbon and energy. P. cepacia also utilizes 3-fluorobenzoate. Except for A. eutrophus JMP134, which is known to grow with 2,4-dichlorophenoxyacetate and 3...
متن کاملAlcaligenes eutrophus as a bacterial chromate sensor.
In Alcaligenes eutrophus CH34, determinants encoding inducible resistance to chromate (chr) and to cobalt and nickel (cnr) are located adjacent to each other on plasmid pMOL28. To develop metal-sensing bacterial strains, a cloned part of plasmid pMOL28, which contains both determinants, was mutated with Tn5-lacZ. The chr::lacZ fusions were specifically induced by chromium; cnr was induced best ...
متن کاملFactors influencing 4-fluorobenzoate degradation in biofilm cultures of Pseudomonas knackmussii B13.
Membrane aerated biofilm reactors (MABRs) have potential in wastewater treatment as they permit simultaneous COD minimisation, nitrification and denitrification. Here we report on the application of the MABR to the removal of fluorinated xenobiotics from wastewater, employing a Pseudomonas knackmussii monoculture to degrade the model compound 4-fluorobenzoate. Growth of biofilm in the MABR usin...
متن کاملDissimilation of aromatic compounds by Alcaligenes eutrophus.
The range of aromatic compounds that support the growth of Alcaligenes eutrophus has been determined, and the pathways used for the dissimilation of these substrates have been explored, largely by enzymatic analyses. The beta-ketoadipate pathway operates in the dissimilation of benzoate and p-hydroxybenzoate; the genetisate pathway, in the dissimilation of m-hydroxybenzoate; and the meta cleava...
متن کاملMaleylacetate reductases in chloroaromatic-degrading bacteria using the modified ortho pathway: comparison of catalytic properties.
The maleylacetate reductases from Pseudomonas aeruginosa RHO1 and Alcaligenes eutrophus JMP134 were tested for activity and affinity to various maleylacetates as well as dechlorinating properties. The dechlorinating activity and the kcat/Km values revealed high-level similarity of these reductases to that of Pseudomonas sp. strain B13.
