Biopiling is an ex situ bioremediation technology that has been extensively used for remediating a wide range of petrochemical contaminants in soils. Biopiling involves the assembling of contaminated soils into piles and stimulating the biodegrading activity of microbial populations by creating near optimum growth conditions. Phytoremediation is another very successful bioremediation technique ...

Rhizoremediation is increasingly becoming a green and sustainable alternative to physico-chemical methods for remediation of contaminated environments through the utilization symbiotic relationship between plants their associated soil microorganisms in root zone. The overall efficiency can be enhanced by identifying suitable plant-microbe combinations specific contaminants supporting process wi...

Crude oil exploration is associated with spillage causing environmental degradation including loss of soil fertility and biodiversity. Various technologies are available for remediating crude polluted soil, but, bioremediation seems to be more environmentally friendly cost effective. Thus, the current work on using cow dung wire croton leave as amendments. It was conducted a batch process monit...

Abstract The activities of the petroleum mining industry in Indonesia have caused many problems by producing hazardous waste pollution that would produce dangers for plants, animals or human lives. One technique to recover environmental situation is through land farming technique. purpose this study overcome crude oil environment using biotechnology method process enzymatic bioremediation. para...

Background: The application of phytoremediation by utilizing plants has been used to control oil pollution in waters. One the that can act as a phytoremediator is hyacinth because this plant reduce various pollutants including petroleum hydrocarbons. This study aims reduction ability hydrocarbons at different concentrations improving water quality. <ns...

Bacterial community dynamics were investigated in a land treatment unit (LTU) established at a site contaminated with highly weathered petroleum hydrocarbons in the C(10) to C(32) range. The treatment plot, 3,000 cubic yards of soil, was supplemented with nutrients and monitored weekly for total petroleum hydrocarbons (TPH), soil water content, nutrient levels, and aerobic heterotrophic bacteri...

Large pilot scale bioremediation approaches were implemented for the treatments of oily sludge (OS) characterised by alkaline pH (pH > 9), high concentration metals (3% dry weight) and total petroleum hydrocarbons content (TPH) rangingbetween 22,000 67,300 mg kg ?1 from a Tunisian refinery. The included bioaugmentation biostimulation with autochthonous isolated bacterial strains consortia. Chem...

Biodegradation of petroleum hydrocarbons in cold environments, including Alpine soils, is a result of indigenous cold-adapted microorganisms able to degrade these contaminants. In the present study, the prevalence of seven genotypes involved in the degradation of n-alkanes (Pseudomonas putida GPo1 alkB; Acinetobacter spp. alkM; Rhodococcus spp. alkB1, and Rhodococcus spp. alkB2), aromatic hydro...

This paper presents a quantitative method for the risk-based evaluation of Total Petroleum Hydrocarbons (TPH) in vapor intrusion investigations. Vapors from petroleum fuels are characterized by a complex mixture of aliphatic and, to a lesser extent, aromatic compounds. These compounds can be measured and described in terms of TPH carbon ranges. Toxicity factors published by USEPA and other part...
