Bioremediation of oil contaminated land

Abstract

An intensive laboratory investigation was undertaken in order to establish the feasibility and strategy for treating soil contaminated with oil at a refinery site.

Phytoremediation

“…Popular methods include soil moisture probes that measure the electrical conductivity of the soil, lysimeters that collect water that passes through the root zone, and tensiometers that measure soil matric potentials related to soil water content. Other methods include gamma densitometry, neutron moderation, resistance blocks, and time-domain reflectometry [102,103].…”

“…Physiochemical factors that determine the suitability of the soil environment as microbial habitats, and thus, sites for biodegradation are given in Table 2. Bacteria are the principal microbiota that mineralize many organic contaminants with numerous studies documenting their degradation capabilities [82,[96][97][98][99][100][101][102][103][104][105][106][107][108][109][110][111][112]. The predominant microorganisms are Pseudomonas, Mycobacterium,Actinobacter,Flavobacterium,Arthrobacter,Bacillus,and Nocardia [11,83,113].…”

Evaluation of the performance of two commercial starters on the bioremediation of soils contaminated with mineral oil and HCH (Hexachlorocyclohexane)

“…Atlas (1981), working with kerosene, reported a rate around 0.2 g kerosene-kg soil'.day-' under his best conditions (kerosene is more readily biodegradable than used mineral oil). Ellis et al (1990) obtained under their best conditions a biodegradation rate of 0.05 g oil-kg soil-'-day-'. Finally, found an optimum biodegradation rate around 0.18 g oilkg soil'eday-'.…”

The influence of oil contaminated soil on the quality of surface waste water

“…Biological methods of soil treatment with the use of hydrocarbon oxidizing microorganisms are widely used among the well known techniques (Schussler 1986;Gerbhardt 1987;Ellis et al 1990;Margesin et al 2000;Beškoski et al 2011).…”
