Denitrification by Alcaligenes eutrophus is plasmid dependent.

چکیده
Curing of the hydrogenase-specifying megaplasmid pHG indigenous to strains of the facultative lithoautotrophic bacterium Alcaligenes eutrophus was correlated with a loss of denitrifying ability (Nitd). The retransfer of plasmid pHG1 reconstituted the Nitd phenotype. Plasmid-free mutants were still capable of converting some nitrate to nitrite, but they did not metabolize nitrite under anaerobic conditions.

Identification of a catabolic transposon, Tn4371, carrying biphenyl and 4-chlorobiphenyl degradation genes in Alcaligenes eutrophus A5.
Alcaligenes eutrophus A5 catabolizes biphenyl to CO2 via benzoate and 4-chlorobiphenyl to 4-chlorobenzoate. In curing and conjugation experiments, the A5 endogenous 51-kb IncP1 plasmid pSS50 was found to be dispensable for biphenyl and 4-chlorobiphenyl catabolism. Transfer of the biphenyl- and 4-chlorobiphenyl-degrading phenotype by means of pSS50 was observed at a frequency of 10(-5) per trans...
متن کاملCloning and expression of the levanase gene in Alcaligenes eutrophus H16 enables the strain to hydrolyze sucrose
Genetic engineering methods were used to enhance the substrate spectrum of Alcaligenes eutrophus H16, a poly-fl-hydroxybutyric acid (PHB) producer. Using parts of the vector pMMB33 and a 2.5 kb DNA fragment of the Bacillus subtilis chromosome a plasmid was constructed bearing the gene for levanase, an enzyme able to hydrolyze various saccharides. After transfer of the levanase gene by triparent...
متن کاملChromosomal and plasmid locations for phosphoribulokinase genes in Alcaligenes eutrophus.
Genes coding for phosphoribulokinase (PRK), a key enzyme of the Calvin cycle, were localized in the genome of the chemoautotroph Alcaligenes eutrophus. The NH2-terminal sequence of the PRK subunit was determined. With a synthetic oligodeoxynucleotide probe complementary to a portion of this sequence, hybridization analysis revealed PRK genes to be located on both the chromosome and the megaplas...
متن کاملNaturally occurring genetic transfer of hydrogen-oxidizing ability between strains of Alcaligenes eutrophus.
Mutants defective in chemolithoautotrophic growth (Aut-) have been isolated from Alcaligenes eutrophus strains H16, N9A, G27, and TF93. Spontaneous Aut- mutants were obtained only with strain TF93. Mutants of the other strains were selected after conventional mutagenesis or treatment with mitomycin. Most of the mutants, including the spontaneous Aut- strains, lacked hydrogenase activity (Hox-) ...
متن کاملOne-Factor-at-a-Time Optimization of Polyhydroxybutyrate Production and Growth of Alcaligenes eutrophus by Altering Culture Parameters and Incubation Time
Polyhydroxyalkanoates (PHAs) are bioplastics derived from renewable resources such as vegetable oils, corn starch, or microbes. The polyhydroxybutyrate (PHB) is a short-chain-length PHA, and the most important bioplastic produced by certain microorganisms in the presence of excess carbon sources. In this study batch cultivation of Alcaligenes eutrophus with the aim of increasing PHB production ...
