Crude Oil Degrading Bacteria

Brooijmans et al 2009. The oil emulsification index was found to be in the range of 25 to 54.

Enrichment And Isolation Of Crude Oil Degrading Bacteria Download Scientific Diagram

The crude oil used in the experiment was derived from laboratory-simulated crude oil 0 diesel oil.

. Degradation and they work as primary degraders of spilled oil in environment Rahman et al 2003. Crude-oil contamination oil-degrading bacteria 16S rDnA Gc-MS analysis activity of degradation related enzyme Introduction crude oil is mainly composed of alkanes cycloalkanes and aromatic alkanes which constitute about 50 to 80 of the oil content. Similar studies have been.

A total of six pure cultures which could utilize crude oil as the sole carbon and energy source were isolated on the LB agar slants under similar conditions. We obtained crude oil degradation bacteria from oilcontaminated sediment especially the Gordonia sp. Several bacteria are even known to feed exclusively on hydrocarbons Yakimov et al 2007.

The excess sludge of the Yangzi Petrochemical Wastewater Treatment Plant Nanjing China was used as a bacterial source for screening petroleum hydrocarbon-degrading bacteria. 100 mL of crude oil medium SM and 02 gmL yeast extract powder were placed in a clean conical flask and 2 mL of the collected oil polluted seawater samples was injected by sterile syringe to the crude oil medium on the clean workbench which was sterilized. Crude Oil Degrading Bacteria.

About 50ml medium was dispensed in 250ml conical flasks. Through the de novo whole genome sequencing confirmed the alkane degrading related gene such as alkane1monooxygenase. For examining the degradation of oil Bushnell Haas medium BHM supplemented with 5gl of crude oil was used.

Bacteria were isolated by means of the enrichment culture technique Liu et al. In this survey 25 crude-oil-degrading bacteria were isolated from marine environments in Iran including the Persian Gulf and the Caspian Sea. The growth and isolation of oil-degrading bacteria with morphological differences were performed on MSM containing crude oil as the only energy and carbon source.

Petroleum hydrocarbon degrading bacteria was as follows. There is no full clarity though on what in the absence of petroleum their natural niches are. The media was inoculated with 01ml of crude oil degrading bacteria bacteria obtained by screening of crude oil degrading bacteria and incubated at 28C for 7 days.

Heavy oil 11 mixture. Co17 was shown highest efficiency 842. Two hundred and fifty millilitre Erlenmeyer flasks containing 100 ml of sterile mineral salts medium 15 g of compost samples 15 and 1 ml of crude oil sludge 1 were incubated in a rotary incubator at 130 revolutions per minute rpm and 28 C.

To learn more. 100 mL of crude oil medium SM and 02 gmL yeast extract powder were placed in a clean conical flask and 2 mL of the col-lected oil polluted seawater samples was injected by sterile syringe to the crude oil medium on the clean workbench which was sterilized. There is emerging interest in the anaerobic degradation of crude oil.

Few studies pointed at s. The separation of petroleum hydrocarbon degrading bacteria was as follows. Eleven strains were selected from among the 25 isolated strains for further study based on their high growth rates on crude oil and high levels of hydrocarbon degradation.

The crude oil degradation rate was 565 to 864. Isolation Growth and Biodegradation Studies. We found that selected isolates were able to degrade burned out engine oil efficiently in contrast to petrol and diesel.

These constituents are called petroleum hydrocarbons for short 9. A sensitive crude oil bioassay indicates that oil spills potentially induce a change of major nitrifying prokaryotes from the Archaea to the Bacteria. Marine hydrocarbon-degrading bacteria play an important role in natural petroleum biodegradation processes and were initially associated with man-made oil spills or natural seeps.

However there is limited knowledge about the geochemical effects and microbiological activities for it. Molina GA Barreto JC. Oil-degrading bacteria are essential in marine environments that are subject to frequent natural and anthropogenic seepage.

The main objective of this study is to isolate and characterize crude oil degrading bacteria in. After the 540-day incubation bacteria of unknown classifications were dominant in the thermophilic methanogenic consortia whereas Clostridium dominated the. The results of this research showed the potential of Alcaligenes faecalis OV1 to be used in the bioremediation of crude oil-contaminated.
