Mycotic flora in vermicultures and intestines of Eisenia andrei
Nováková, Alena ; Pižl, Václav
In spring and autumn 2000, microscopic fungi associated with fresh and processed substrates and with the intestines of Eisenia andrei were studied in three vermiculture plants differing in their productivity. 119 species and 6 forms of microscopic fungi were isolated. Of those, 97 taxa were recorded from vermiculture substrates and 76 taxa from worm intestines. In vermiculture substrates, Aspergillus fumigatus, A. niger, Geotrichum candidum, Penicillium expansum and P. roquefortii were dominant among taxa isolated by soil dilution plate method, and Rhizopus stolonifer was most frequently isolated by soil washing technique. A. fumigatus, Mucor circinelloides f. circinelloides and P. expansum predominated in the intestines of earthworms. Processed vermiculture substrates regularly yielded higher numbers of cultivable micromycetes (CFU-counts) than fresh ones. The CFU-counts of earthworm intestines were close to those of processed substrates in two vermiculture plants studied. In the third plant, however, intestinal CFU-count was the same as that found in fresh vermiculture substrate.
