Abstract
The aim of this work was to test the suitability of microbiological methods for the ecotoxicological evaluation on the example of soils of two sites (I and II) (more and less contaminated and situated in Saxony-Anhalt, Germany). Contents of Zn, Pb, Cd, Ni, Cr, and Cu in soil ranged 787-210, 210-110, 8-1, 49-12, 130-17, and 161-70 mg kg-1, respectively being significantly higher in site I. The sites differ also in respect to pH (5.2-7.5), C org (5.66-8.27%) and type of soil. The parameters tested were following: substrate-induced respiration (SIR), activity of luminous bacteria, substrate utilization patterns on BIOLOG ECO-and GN-plates, and phospholipid fatty acid (PLFA) profiles. The respiratory coefficient QR, peak respiratory maximum and BIOLOG ECO-plates were suitable for an ecotoxicological assessment of contaminated soils. QR values (> 0.3) and peak maximum values (> 40 h) indicated stress of soil microorganisms at the most heavy metal contaminated site (site I). PLFA analysis can be used to detect various environmental stresses in the soil. The trans/cis ratio of monosaturated fatty acids (> 0.1) and the fungal/bacterial biomass ratio were able to distinguish the stress conditions in soils connected with heavy metal contamination. With increasing heavy metal content in soils the PLFA pattern are changed directionally.
