Anaerobic bioremediation approach to remove TPH contaminated soil
Total petroleum hydrocarbon (TPH) is a complex mixture of hydrocarbons including saturate fraction such as n-alkanes, branched alkanes, and cycloalkanes (naphthenes). TPH is normally come from the accidental leakage of storage tanks of lubricating and fuel oils resulting in the soil contamination. TPH is classified as the hazardous material and is considered as the most organic pollutants in th...
متن کاملAnaerobic Naphthalene Degradation by a Sulfate-Reducing Enrichment Culture
Anaerobic naphthalene degradation by a sulfate-reducing enrichment culture was studied by substrate utilization tests and identification of metabolites by gas chromatography-mass spectrometry. In substrate utilization tests, the culture was able to oxidize naphthalene, 2-methylnaphthalene, 1and 2-naphthoic acids, phenylacetic acid, benzoic acid, cyclohexanecarboxylic acid, and cyclohex-1-ene-ca...
متن کاملBioremediation of Soil Contaminated by Diesel Oil
Were evaluated natural attenuation, biostimulation and bioaugmentation on the degradation of total petroleum hydrocarbons (TPH) in soils contaminated with diesel oil. Bioaugmentation showed the greatest degradation in the light (C12 C23) fractions (72.7%) and heavy (C23 C40) fractions of TPH (75.2%) and natural attenuation was more effective than biostimulation. The greatest dehydrogenase activ...
متن کاملAnaerobic cometabolic conversion of benzothiophene by a sulfate-reducing enrichment culture and in a tar-oil-contaminated aquifer.
Anaerobic cometabolic conversion of benzothiophene was studied with a sulfate-reducing enrichment culture growing with naphthalene as the sole source of carbon and energy. The sulfate-reducing bacteria were not able to grow with benzothiophene as the primary substrate. Metabolite analysis was performed with culture supernatants obtained by cometabolization experiments and revealed the formation...
متن کاملArsenic Methylation Dynamics in a Rice Paddy Soil Anaerobic Enrichment Culture.
Methylated arsenic (As) species represent a significant fraction of the As accumulating in rice grains, and there are geographic patterns in the abundance of methylated arsenic in rice that are not understood. The microorganisms driving As biomethylation in paddy environments, and thus the soil conditions conducive to the accumulation of methylated arsenic, are unknown. We tested the hypothesis...
