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 کاملEnrichment, isolation, and phylogenetic identification of polycyclic aromatic hydrocarbon-degrading bacteria from Elizabeth River sediments.
The diversity of indigenous bacteria in sediments from several sites in the Elizabeth River (Virginia) able to degrade multiple polycyclic aromatic hydrocarbons (PAHs) was investigated by the use of classical selective enrichment and molecular analyses. Enrichment cultures containing naphthalene, phenanthrene, fluoranthene, or pyrene as a sole carbon and energy source were monitored by denaturi...
متن کاملCharacterization of Aromatic Hydrocarbon Degrading Bacteria Isolated from Pine Litter
Using a novel pine needle agar, fifteen bacterial species were isolated from pine litter. These bacteria were able to degrade aromatic hydrocarbons derived from lignin and utilize the ortho-cleavage of the β-ketoadipate pathway to degrade protocatechuate or catechol. A different utilization array of aromatic hydrocarbons by these bacteria was also determined. This study provides the information...
متن کاملChemotaxis in polycyclic aromatic hydrocarbon-degrading bacteria isolated from coal-tar- and oil-polluted rhizospheres.
Abstract The limited mass transfer in polycyclic aromatic hydrocarbon (PAH)-contaminated soils during bioremediation treatments often impedes the achievement of regulatory decontamination end-points. Little is known about bioavailability of these hydrophobic pollutants in phytoremediation systems. This work attempts to evaluate, for the first time, chemotaxis as a bioavailability-promoting trai...
متن کاملجدا سازی باکتری های تجزیه کننده هیدروکربن های آروماتیک چند حلقه ای (PAH) از دریاچه مهارلو و بررسی اثر غلظت نمک در تجزیه آن ها
Background and Aim: In this research we isolated the bacterial species degrading polycyclic aromatic hydrocarbons (PAHs) and determined optimal salt concentration for PAH degradation.Materials and Methods: We used naphthalene and anthracene as the only sources of carbon for isolating PAH-degrading bacteria the main culture medium was ONR7a. The bacteria isolated by this method were used for the...
