“…Release of petroleum products such as hydrocarbons and metals due to dumping of petroleum waste or oil spillage contaminates our biosphere. Hydrocarbons and metals from petroleum possess a number of toxic properties: they are mutagenic and carcinogenic in nature and impair kidneys and liver in animals [3]. Soil used in this experiment was contaminated with petroleum and was collected from an area close to refinery which was analyzed for total hydrocarbons, metals, and bacterial population.…”

“…Large-scale urbanization and industrialization is the biggest problem of this universe due to the release of large amount of waste which contaminates our biosphere and is the biggest threat to the ecosystem [1]. Petroleum has contamination of metals and hydrocarbons, both of these are components are toxic and carcinogenic to animals and humans and is the biggest problem of oil-producing countries [2,3]. Aliphatic, aromatic, cycloaliphatic hydrocarbons, and metallic substances such as cadmium, chromium, nickel, lead, and so forth are the main pollutants in petroleum.…”

Careless handling of petroleum in petrochemical industries releases toxic hydrocarbons and metals to soil and water. The aim of the present study was to isolate hydrocarbon‐utilizing and metal‐tolerant bacteria. Hydrocarbon‐utilizing bacteria from petroleum‐contaminated soils were isolated on the Bushnell Hass medium. Hydrocarbon degradation by Pseudomonas taiwanensis strain YSA‐17 was observed by gas chromatography–mass spectrometry. Bioaccumulation of metals by strain YSA‐17 was assessed in nutrient broth. Among different strains, YSA‐17 showed the highest potential for hydrocarbon utilization. After 20 days of incubation, YSA‐17 completely degraded one compound and during its degradation, there was the formation of 13 new compounds which were absent in uninoculated control. Results of scanning electron microscope and Fourier transmission infrared (FTIR) indicated degradation of hydrocarbons. FTIR showed the formation of new functional groups in YSA‐17 inoculated medium. Expression of the total quantity of hydrocarbon‐degrading gene (AlkB and NehAc) in petroleum‐amended nutrient broth inoculated with strain YSA‐17 enhanced significantly during 20 days of incubation compared to control. YSA‐17 also significantly removed metals. This study concluded that bioinoculant can be utilized for the bioremediation of pollutants cocontaminated with hydrocarbons and metals. Petroleum‐contaminated soil will be remediated for pollutants.
