Isolation of adherent polycyclic aromatic hydrocarbon (PAH)-degrading bacteria using PAH-sorbing carriers.
Two different procedures were compared to isolate polycyclic aromatic hydrocarbon (PAH)-utilizing bacteria from PAH-contaminated soil and sludge samples, i.e., (i) shaken enrichment cultures in liquid mineral medium in which PAHs were supplied as crystals and (ii) a new method in which PAH degraders were enriched on and recovered from hydrophobic membranes containing sorbed PAHs. Both technique...
متن کاملDetection of mega plasmid from polycyclic aromatic hydrocarbon-degrading Sphingomonas sp. strain KS14.
Polycyclic aromatic hydrocarbon (PAH) degrading Sphingomonas sp. strain KS14 was isolated from soil. Strain KS14 was able to utilize phenanthrene and naphthalene as sole source of carbon and energy, and mineralize phenanthrene to carbon dioxide. Strain KS14 cometabolically degraded pyrene using phenanthrene as secondary growth substrate. A large degradative plasmid (>500 kb) was detected from t...
متن کاملCharacterization of a polycyclic aromatic hydrocarbon degradation gene cluster in a phenanthrene-degrading Acidovorax strain.
Acidovorax sp. strain NA3 was isolated from polycyclic aromatic hydrocarbon (PAH)-contaminated soil that had been treated in a bioreactor and enriched with phenanthrene. The 16S rRNA gene of the isolate possessed 99.8 to 99.9% similarity to the dominant sequences recovered during a previous stable-isotope probing experiment with [U-(13)C]phenanthrene on the same soil (D. R. Singleton, S. N. Pow...
متن کاملPolycyclic aromatic hydrocarbon degradation of phytoplankton-associated Arenibacter spp. and description of Arenibacter algicola sp. nov., an aromatic hydrocarbon-degrading bacterium.
Pyrosequencing of the bacterial community associated with a cosmopolitan marine diatom during enrichment with crude oil revealed several Arenibacter phylotypes, of which one (OTU-202) had become significantly enriched by the oil. Since members of the genus Arenibacter have not been previously shown to degrade hydrocarbons, we attempted to isolate a representative strain of this genus in order t...
متن کاملIsolation of soil bacteria adapted to degrade humic acid-sorbed phenanthrene.
The goal of these studies was to determine how sorption by humic acids affected the bioavailability of polynuclear aromatic hydrocarbons (PAHs) to PAH-degrading microbes. Micellar solutions of humic acid were used as sorbents, and phenanthrene was used as a model PAH. Enrichments from PAH-contaminated soils established with nonsorbed phenanthrene yielded a total of 25 different isolates represe...
