    Effect of addition ofPseudomonas aeruginosa UG2 inocula or biosurfactants on biodegradation of selected hydrocarbons in soil (1992)
    Springer
    Journal of industrial microbiology and biotechnology 10 (1992), S. 87-93 
    Details
    ISSN: 1476-5535
    Keywords: Availability ; Biosurfactant ; Biodegradation ; Bioemulsifier ; Hydrocarbon ; Persistence ; Pseudomonas aeruginosa ; Solubility

    Notes: Summary A laboratory study was undertaken to assess the effect of adding eitherPseudomonas aeruginosa UG2 cells or the biosurfactants produced by this m microorganism on the biodegradation of a hydrocarbon mixture in soil at 20°C over a 2-month incubation period. The addition of 100 μg of UG2 biosurfactants per g soil significantly enhanced the degradation of tetradecane, hexadecene and pristane but not 2-methylnaphthalene, the most water-soluble of the hydrocarbons. Addition of UG2 cells at densities of 106, 107, and 108 per g soil did not have a significant effect on biodegradation of the hydrocarbon mixture.

    Evaluation of microbial surfactants for recovery of hydrophobic pollutants from soil (1993)
    Springer
    Journal of industrial microbiology and biotechnology 11 (1993), S. 163-170 
    Details
    ISSN: 1476-5535
    Keywords: Acinetobacter calcoaceticus ; Bioemulsifier ; Biosurfactant ; Hydrophobic ; Hydrocarbon ; Pseudomonas aeruginosa ; Partitioning ; Recovery ; Remediation ; Soil

    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Summary Several microbially produced biosurfactants were evaluated for their ability to remove hydrophobic compounds from soil. The biosurfactants produced byPseudomonas aeruginosa UG2 andAcinetobacter calcoaceticus RAG-1 displayed the best results, with recovery of [14C]hexachlorobiphenyl from soil slurries of 48.0 and 41.9%, respectively.P. aeruginosa UG2 produced higher levels of extracellular biosurfactants than four otherP. aeruginosa strains.P. aeruginosa UG2 culture filtrate containing biosurfactants enhanced the recovery of several other individual hydrocarbons and polychlorinated biphenyl compounds, as well as several hydrocarbons in a mixture, from soil. The results, suggest that biosurfactants produced byP. aeruginosa UG2 have the potential for remediation of hydrophobic pollutants in soil environments.
