Bench-scale production of enzymes from the hydrocarbonoclastic bacteria Alcanivorax borkumensis and biodegradation tests

Enzymatic degradation tested on two different polycyclic aromatic hydrocarbons (PAHs) contaminated groundwaters showed 37.4% removal after 5 days with a degradation rate of 196.6 ppb day−1 and 82.8% removal after 10 days with a degradation rate of 217.54 ppb day-1 for the 1st site and an almost complete biodegradation with 95% removal and 499.02 ppb day−1 removal rate after only 5 days for the 2nd site.
