Abstract
Petroleum oil as a vast source of energy widely used in the whole world in several sectors especially in industry and transportation. The leakage or contamination of oil from pipeline, tank, and industry as a form of oil sludge with soil can produce major environmental and health hazard. Bioremediation is one of the most economical and environmentally safe technology to prevent this contamination though it takes longer time. This paper reviews the basic processes involved in bioremediation, types and the factors affecting it. This study includes some previously adopted different bioremediation methods varies with different process material such as refinery treatment sludge, sewage sludge, microbial organism, bulking agents and different chemical additives. The comparison of these methods is presented in respect of the removal efficiency of an entire process as well as the TPH (Total Petroleum Hydrocarbon), aliphatic, aromatic, resins, asphaltene fraction of oil sludge within the different period of time.

Petroleum is the major source of energy for various industries and daily life. Releasing petroleum into the environment whether accidentally or due to human activities is a main cause of soil pollution. Soil contaminated with petroleum has a serious hazard to human health and causes environmental problems as well. Petroleum pollutants, mainly hydrocarbon, are classified as priority pollutants. The application of microorganisms or microbial processes to remove or degrade contaminants from soil is...

Objective: In order to study the microbial remediation of oil contaminated soil. Methods: The method of soil composting was adopted. G-40, G-94 and G-40 G-94 were added into the soil with 2% oil, adding 20% bran and adding distilled water to keep the soil water content in 35%, and it was incubated at 35℃. After sampled, the alkali hydrolysable nitrogen, available phosphorus and oil content were measured. Result: The oil removal rates of G-40, G-94 and G-40 G-94 treatment groups were 29.08%, 31.0...

Abstract Petroleum hydrocarbons are the most widespread contaminants in the environment. Soil contamination with crude oil tank bottom sludge (COTBS) represents a significant risk to both human and environmental health. Current traditional approaches only partially resolve the issue as they are inefficient, expensive, not environmentally friendly and leave behind unwanted products; hence, there is an urgent need to develop an environmentally friendly and cost effective solution to address this i...

Liamocins are unique heavier-than-water “oils” produced by certain strains of the fungus Aureobasidium pullulans. Liamocins have antibacterial activity with specificity for Streptococcus sp. Previous studies reported that liamocin yields were highest from strains of A. pullulans belonging to phylogenetic clades 8, 9, and 11, cultured on medium containing sucrose. In this study, 27 strains from these clades were examined for the first time for production of liamocins from agricultural biomass sub...

Environmental pollution has been on the rise in the past few decades owing to increased human activities on energy reservoirs, unsafe agricultural practices and rapid industrialization. Amongst the pollutants that are of environmental and public health concerns due to their toxicities are: heavy metals, nuclear wastes, pesticides, green house gases, and hydrocarbons. Remediation of polluted sites using microbial process (bioremediation) has proven effective and reliable due to its eco-friendly f...

ABSTRACTThe remediation technologies of soils contaminated with petroleum products are developed in two main directions: the first one encompasses searching for new effective bioagents and the other one explores the ways to activate those microorganisms present in the soil that are capable of degrading oil. The objective of this research was to determine if it is possible to increase the effectiveness of biodegradation of petroleum products by using chemical additives. The soil was supplemented ...

Abstract A field bioremediation of oil sludge contaminated soil was conducted by landfarming treatment with added cotton stalks in the Shengli oil field. The ability of landfarming treatment was evaluated to reduce petroleum hydrocarbons and restore soil quality. For 39-month landfarming, the initial concentration of total petroleum hydrocarbons (TPH) was 12.57 mg g −1 for oil sludge contaminated soil. The removal efficiency of TPH, saturated fraction and aromatic fraction was 68.48%, 90.04% and...

Oil sludge is a viscous material consisting of resin, asphaltene, sand, and water, which is usually formed at the bottom of oil reservoir tanks. Asphaltene and resin contents of oil sludge make it more resistant to biodegradation. Disposal of oil sludge is the main problem of oil industry; discharge of oil sludge into the soil causes damage to the environment. Bioremediation is an efficient, cheap, and environmentally friendly method for oil-sludge treatment. The aim of this study was to investi...

A lab-scale experiment was set up to investigate the efficiency of addition 5% (w/w) individually of three different organic solid waste amendments to enhance the rate of degradation at 5% and 15% diesel oil in polluted soil during 18 weeks. A total of 81% and 42% oil loss was recorded in soil amended with soycake at 5% and 15% oil pollution, respectively. The measured δ13C signature of CO2 evolved from amending contaminated soil varied between –24 and –28‰. First-order kinetic model demonstrate...

Oil sludge is a thick viscous mixture of sediments, water, oil and hydrocarbons, encountered during crude oil refining, cleaning of oil storage vessels and waste treatment. Polycyclic aromatic hydrocarbons (PAHs), which are components of crude oil sludge, constitute serious environmental concerns, as many of them are cytotoxic, mutagenic and potentially carcinogenic. Improper management and disposal of oil sludge causes environmental pollution. The adverse effects of oil sludge on soil ecology a...
