Biosurfactant - Producing Bacte- Ria Found in Contaminated and Uncontaminated Soils
نویسنده
چکیده
Microbially produced surfactants have been studied for microbially enhanced oil recovery (MEOR) and the bioremediation of hydrocarbons. However, most of these studies have used biosurfactants produced by one of a small number of pure-culture microbes isolated in a laboratory. In previous work, we determined that biosurfactant-producing microorganisms were naturally present at two hydrocarbon-impacted sites. In this study, we examine the prevalence of biosurfactant producers in uncontaminated soils. Biosurfactant-producing bacteria were found to constitute a significant proportion (up to 35%) of aerobic heterotrophs. Biosurfactant producers were isolated. Isolates were identified primarily as strains of Bacillus and Pseudomonas.

Distribution of biosurfactant-producing bacteria in undisturbed and contaminated arid Southwestern soils.
Biosurfactants are a unique class of compounds that have been shown to have a variety of potential applications in the remediation of organic- and metal-contaminated sites, in the enhanced transport of bacteria, in enhanced oil recovery, as cosmetic additives, and in biological control. However, little is known about the distribution of biosurfactant-producing bacteria in the environment. The g...

Total petroleum hydrocarbon (TPH) contaminations in soils may be toxic to human, plants and cause groundwater contamination. To achieve maximum TpH- reduction and to establish successfull stable vegetation cover in phytoremediation method, various criteria must be considered to choose the plants carefully. In this study, germination and subsequent growth of seven plants were tested in three soi...
متن کاملRemediation of Chromium-Contaminated Soils Using Pseudomonas aeruginosa Strain BS2
The bioremediation of chromium-contaminated soil by a rhamnolipid biosurfactant produced by Pseudomonas aeruginosa strain BS2 has been explored through column studies using uncontaminated soil spiked with toxic concentrations of heavy metals i.e. 1000 mg/kg chromium. Results on removal of chromium from the spiked soil by using di-rhamnolipid and tap water have shown a high potential of di-rhamn...

متن کاملPotential nitrification rate as a tool for screening toxicity in metal-contaminated soils.
A potential nitrification rate test (PNR) was used to identify metal toxicity in field-contaminated soils. The test was applied to metal salt-spiked soils, to 27 uncontaminated soils, and to 15 soils that are contaminated by former metal smelting activities. Four agricultural soils (pH 4.5-6.6) were spiked with various rates of CdCl2 (0-200 mg Cd/kg dry wt) or ZnCl2 (0-3,000 mg Cd/kg dry wt) an...
