ALVARADO-CASTILLO, Gerardo et al. OBTAINING SCLEROTIA OF MOREL MUSHROM (Morchella esculenta) IN DIFFERENT CULTURE MEDIA. INCI [online]. 2008, vol.33, n.7, pp.532-536. ISSN 0378-1844.

Morchella esculenta is an edible mushroom of high commercial value and obtaining sclerotia is considered important for its cultivation. In this work, the growth of the IE-750 strain was studied in eight solid and six liquid culture media. Parameters assessed were mycelial growth, production of biomass, and ability to produce sclerotia and their biomass. The best mycelial growth was obtained in the treatment containing compost extract (T7: 53.87cm²), while the highest production of biomass was recorded in the treatment containing yeast (T3: 80.3mg). Treatments with poultry manure and compost showed 40 and 80% of sclerotia in solid and liquid media, respectively, and the highest sclerotia biomass was recorded in the compost treatment (solid medium). Sclerotia were obtained in periods of 9-12 days (solid medium) and 7-9 days (liquid medium).
