Crude oil and petroleum products have a wide variety of hazardous components with high toxicity and low biodegradability. Certain dyes change their colors by intercepting electron transfer reactions during the transformation processes. This study applied resazurin and 2,6-dichlorophenol-indophenol indicators for a rapid screening biodegradation capability and toxicity response to various petroleum products such as motor oil, diesel, gasoline, and phenol. Colorimetry tests were performed in test… Expand
Petroleum biodegradation capacity of bacteria and fungi isolated from petroleum-contaminated soil
On average, PAH degradation by microbial isolates from soil that was lightly, moderately, and highly contaminated with petroleum was equally efficient, and the type of culture medium used did not significantly impact mean biodegradation. Expand
Purpose: Bioremediation allows specific microorganisms to biodegrade petroleum contaminants, yielding carbon dioxide and water as mineralization products. This study applied an adapted microcosm aExpand
Comparison of the mineralization and biodegradation efficiency of the Fenton reaction and Ozone in the treatment of crude petroleum-contaminated water
Abstract Petroleum contains low biodegradability compounds, requiring powerful oxidants to become mineralized or more biodegradable. This study therefore aimed to compare the efficiency of Fenton’sExpand
Bioremediation of petroleum-contaminated soils using Streptomyces sp. Hlh1
PurposeBioremediation using microorganisms is a promising strategy to remediate soil with petroleum hydrocarbons. Streptomyces sp. Hlh1, an endophytic strain, has previously demonstrated the abilityExpand
Metabolical shifts towards alternative BTEX biodegradation intermediates induced by perfluorinated compounds in firefighting foams.
The research suggests the discovery of an altered metabolic pathway in aromatic hydrocarbons biodegradation that is directly affected by fluorinated substances. Expand
Bioaugmentation and Biostimulation of Total Petroleum Hydrocarbon Degradation in a Petroleum-contaminated Soil with Fungi Isolated from Olive Oil Effluent
In degradation of total petroleum hydrocarbon, 35 isolates belonging to 11 genera were sanitized and 3 isolates as well as their consortium were initiated to be able to raise in association withExpand
Fluorinated waste and firefighting activities: biodegradation of hydrocarbons from petrochemical refinery soil co-contaminated with halogenated foams
It is proposed that transient components of the benzene and toluene degradation may be differentially formed, causing the Benzene, toluenes, and perfluorinated co-contaminations to go through switched metabolic stages under the presence of fluoride in a contamination scenario. Expand
The effects of fluoride based fire-fighting foams on soil microbiota activity and plant growth during natural attenuation of perfluorinated compounds.
It is argued that the long-term biotransformation of fire-fighting foams should be taken in to account when evaluating toxicity, focusing on a time-based monitoring analysis, since potentially toxic intermediates may be formed though biodegradation. Expand
DCPIP and Respirometry Used in the Understanding of Ametryn Biodegradation
In view of an environmental scenario of degradation of the terrestrial ecosystem due to the indiscriminate use of organic compounds, it is necessary to use complementary techniques to evaluate theExpand
Technical approaches to evaluate the surfactant-enhanced biodegradation of biodiesel and vegetable oils
The data output was successfully combined with mathematical models and statistical tools to describe and predict the actual environmental behavior of biodiesel and vegetable oils and confirmed and predicted the biodegradation effectiveness with biosurfactants and the required timeframe to achieve satisfactory contaminant removal.

Crude Oil Hydrocarbon Bioremediation and Soil Ecotoxicity Assessment
In this study, we determined the limits and extent of hydrocarbon biodegradation, earthworm and plant toxicity, and waste leachability of crude oil-containing soils. Three oils (heavy, medium, andExpand
11 – Biodegradation of oil hydrocarbons and its implications for source identification
Publisher Summary Biodegradation puts a major impact on the composition of petroleum products and crude oils. This chapter discusses the fundamentals of hydrocarbon biodegradation, especially ofExpand
Are aromatic hydrocarbons the primary determinant of petroleum toxicity to aquatic organisms
Abstract Aromatic components of oil, particularly polycyclic aromatic hydrocarbons (PAHs), are generally assumed to be the toxic fraction of spilled petroleum. We evaluated this assumption byExpand
Biodegradation of oil hydrocarbons and its implications for source identification
Biodegradation puts a major impact on the composition of petroleum products and crude oils. This chapter discusses the fundamentals of hydrocarbon biodegradation, especially of liquid fossil fuels,Expand
Promoted biodegradation and microbiological effects of petroleum hydrocarbons by Impatiens balsamina L. with strong endurance.
I. balsamina L. to phytoremedy petroleum contaminated soil from the Shengli Oil Field in Dongying City, Shandong Province, China, was examined and it was found that the plant had a good tolerance to contaminated soils with ≤10,000 mg/kg of PHCs. Expand
Evaluation of the phytotoxicity of polycontaminated industrial effluents using the lettuce plant (Lactuca sativa) as a bioindicator.
Germination tests conducted using synthetic solutions confirmed that mixtures of metals have higher toxicity than the sum of their separate constituents, and could be routinely used to check the impact of industrial discharges, even when they meet regulatory requirements for the individual metals. Expand
Bacteria, yeasts and filamentous fungi are the most important hydrocarbon degraders in freshwater systems, and the ability to degrade hydrocarbons is widespread throughout these groups, and members of the saturate and aromatic fractions are most readily degraded. Expand
Groundwater toxicity assessment using bioassay, chemical, and toxicity identification evaluation analyses
Results suggest that these in‐vitro tests can be credible alternatives to whole‐organism bioassays for monitoring remediation of system effluents and that they can complement chemical analyses with useful effects‐based toxicity data. Expand
Determination of naturally occurring MTBE biodegradation by analysing metabolites and biodegradation by-products.
Among the degradation products, TBA was found to be a useful intermediate to identify MTBE degradation, at least under microaerobic conditions, and significantly accumulated as an intermediate by-product. Expand
Photo-induced toxicity of four polycyclic aromatic hydrocarbons, singly and in combination, to the marine diatom Phaeodactylum tricornutum.
The results indicated that simulated solar UV radiation not only enhanced the toxicity of the different PAHs to this alga, but also changed their relative toxic strengths, revealing a complex pattern of possible interactions ofPAHs with marine diatoms. Expand
