by the strong colonization of the pathogen hypha by the yeast
cells (see arrows in Fig. 5C, D, G and H), was also observed. Mycoparasitism is one of the mechanisms involved in phytopathogen
biocontrol and the present study indicated that the yeasts parasitize
C. gloeosporioides hyphae and cause physical damage, possibly due
to the production of hydrolyte enzymes that degrade the hyphae
cell walls, such as -1,3-glucanase. The yeast penetration of walls
with marked concavity formation on hypha cell walls is highlighted
by arrows in Fig. 5G and H
