Degradsdoras petroleum hydrocarbon TPH degradation was evaluated through SARA analysis, employing gas chromatography with an FID detector and infrared spectroscopy to analyze the aliphatic and aromatic hydrocarbon fractions, respectively. The present study has demonstrated that the bacterial strains selected are able to use hydrocarbons as sole carbon source when grown in pure cultures.

Bacterias marinas con capacidad antimicrobiana aisladas de moluscos bivalvos en cultivos. Robust hydrocarbon degradation and dynamics of bacterial communities during nutrient-enhanced oil spill bioremediation. The cultures were discarded after 15 days.

Each strain was assayed in triplicate.

Biosurfactant-enhanced degradation of residual hydrocarbons from slip bilge wastes. The increased levels of phenols and phenoxides may be directly related to the accumulation of end compounds produced by the degradation of resins and asphaltenes. Online J Biol Sci.

Comparative physiology of phenanthrene degradation by two dissimilar pseudomonads isolated from a creosote-contaminated soil. Strain selection All 33 isolated strains were grouped according to culture, morphological, physiological and biochemical parameters. Microbiol Mol Biol Rev. Strain F10S1 lowered the concentration of all fractions in comparison with the control.

It has been shown that strain WW1 of Alcaligenes denitrificans can degrade four-ring polyaromatic hydrocarbons [30]. The strains Alcaligenes sp. A Mycobacterium strain with extended capacities for degradation of gasoline hydrocarbons.


Introduction to the Archaea by JuanCho Rios on Prezi

A microbiological survey of the western Cuban continental shelf found this species in both northern and southern locations [27]. At the end, 18 strains representing each unique combination of these parameters were chosen to be subjected to the selection process. Five replicates were used per sample. No alkanes with backbones shorter than 12 carbon atoms were detected in these samples. ABSTRACT The petfoleo of aerobic marine bacteria able to degrade hydrocarbons represents a promising alternative for the decontamination of oceanic and coastal environments.

SPE International conference on health, safety, and environment in oil and gas exploration and production, JuneCaracas, Venezuela. The concentration of associated hydroxyl groups OH -cm -1 increased for degtadadoras treatments, as did that of degrradadoras groups cm Microbial Transformation and degradation of toxic organic chemicals. Two of these strains were phenotypically identified as sp. The organic phase of the samples was extracted with 45 mL of HPLC-grade dichloromethane three extractions with a volume of 15 mL each using the liquid-liquid method for 30 min in a separating funnel, filtering the obtained organic extract through anhydrous reagent grade sodium sulfate.

Effects of rhamnolipid biosurfactants on removal of phenanthrene from soil. Accepted for publication in January, Culturing these strains in the presence of hydrocarbons Mesa 30 crude favored the expression of enzyme systems involved in their degradation and the preferential isolation of hydrocarbon-tolerant clones. Enrichment, isolation, and phylogenetic identification of polycyclic aromatic hydrocarbon-degrading bacteria from Elizabeth River sediments.

Some species of this genus have been isolated from marine environments contaminated with hydrocarbons [5, 17, 28]. Field evaluations of marine oil spill bioremediation.


Comparative study of five polycyclic aromatic hydrocarbon degrading bacterial strains isolated from contaminated soils. Simultaneous degradation of bacetrias and phenol by Pseudomonas sp. Morphological descriptions were based on bacterial shape, motility and pigmentation. Characterization of the hydrocarbon degradation capacity of the selected strains The ability to degradadorsa hydrocarbons from crude oil Mesa 30 crude was determined after 45 days of static culture.

Publications reporting the presence of this genus in hydrocarbon-contaminated ecosystems and describing its hydrocarbon-degrading abilities have appeared in the literature from the early nineties [17], although its numbers have increased as of late [19, 24, 25, 31, 32].

The degradation potential exhibited by these new isolates warrants further studies on their possible application to decontaminate coastal environments affected by oil spills. Viewed as a whole, the latter possess the necessary genetic information to produce all the enzymes required to completely degrade complex hydrocarbon mixtures in damaged areas [4, 5].

Bioremediation potential of terrestrial fuel spills. Description of toluene inhibition of methyl bromide biodegradation in seawater and isolation of a marine toluene oxidizer that degrades methyl bromide.

Five strains belonging to the latter group could not be identified with the biochemical tests employed in this study.
