heal.abstract Olive mill wastewater (OMW) is rich in potentially toxic organics precluding its disposal into water receptors. However, land application of diluted OMW may result in safe disposal and fertilization. In order to investigate the effects of OMW on the structure of soil fungal groups, OMW was applied daily to pepper plants growing in a loamy sand and a sandy loam at two doses for a period of 3 months (total OMW equivalents 900 and 1800 m3 ha-1). Nitrogen (N) fertilization alleviated N scarcity and considerably enhanced plant biomass production; however, when applied in combination with the high OMW dose, it induced plant stress. OMW applications resulted in marked changes in the denaturing gradient gel electrophoresis patterns of soil basidiomycete communities, while concurrent N fertilization reduced these effects. In contrast, the ascomycete communities required N fertilization to respond to OMW addition. Cloning libraries for the basidiomycete communities showed that Cryptococcus yeasts and Ceratobasidium spp. dominated in the samples treated with OMW. In contrast, certain plant pathogenic basidiomycetes such as Thanatephorus cucumeris and Athelia rolfsii were suppressed. The observed changes may be reasonably explained by the capacity of OMW to enrich soils in organic substrates, to induce N immobilization and to directly introduce OMW-derived basidiomycetous yeasts. © 2009 Federation of European Microbiological Societies.
