ABSTRACT
Soil fungi play a key role in decomposition processes that mineralize and recycle plant nutrients. In the soil environment, fungi interact with a complex microbial community, including bacteria, actinomycetes (actinobacteria) and with small invertebrates. Fungi are also an important part of the food chain within the soil environment, mainly for the soil-inhabiting mesofauna (Bonkowski et al, 2000). In agro-ecosystems, plant pathogens act in soil and the rhizosphere causing reduction of yield and quality (Wainwright, 1988; Lodge, 1993).
