Optimization of production of chlamydospores of the nematode-trapping fungus Duddingtonia flagrans in solid culture media.

The large-scale production of nematophagous fungi as agents of biological control is one of the main challenges to be commercially used. In order to improve growth of microorganism in a culture medium, the addition of growth inducer is common. At the moment, the action of their addition in the mycelia growth and sporulation rate of nematophagous fungi is not known.
