Abstract
We investigated the effect of Chlorpyrifos on a bacterial community. In accordance with results of other groups treatment with Chlorpyrifos in normal concentrations seems to be without influence on the majority of bacteria. But in contrast to previous results we found by SSCP-fingerprinting that few bacteria among Arthrobacter and Klebsiella/Serratia were influenced over few months. The sequence behind the increased bands 1 and 2 in two Arthrobacter-fingerprints (Abb. 1) matched Arthrobacter sulfureus with a similarity of 100%. The decreased band 1 of Klebsiella/Serratia-fingerprints (Abb. 2) in summer was identified as an uncultured agricultural soil bacterium. The increased band 2 seems to be another uncultured bacterium. No shifts were found for Pseudomonas and Streptomyces. So it seems that some species benefited from this treatment whereas other species were inhibited. Now the following question arises. Are direct or indirect influences on soil bacteria responsible for changes in the community¿
