Hochsch., Diss., 1998 AB - In the last years the biodegradation of polycylic aromatic hydrocarbons (PAH) for the bioremediation of polluted soils was studied. Important for a successfull remediation is the degradation of the high molecular weight PAH, a major class of carcinogenic and persistent organic compounds. So the aim of this work was to study the biodegradation of the 5-ring benzo[a]pyrene (BaP) as a priority pollutant of the high molecular weight PAH. With the use of 14C labeled BaP the degradation could be quantified. The biodegradation of this PAH is assumed to be limited by the low water solubility of this compound. A non-ionic surfactant increased the concentration of BaP in the culture medium because of solubilization. The influence of this solubilization on the biodegradation was investigated. A mixed culture of microorganisms isolated from a PAH-contaminated soil was able to degrade 14C labeled BaP in mineral medium by cometabolism with phenanthrene, fluoranthene, anthracene and pyrene as sources of C and energy.
