Abstract: | Zoosporic fungi constitute a large group of true fungi which inhabit freshwater, brackish, marine and soil ecosystems. In
general, very little is known about the effects of antifungal substances on the growth and survival of most species. This
review focuses on experimental research with those isolates which have been studied, especially in some species of Synchytrium, Olpidium, Batrachochytrium, Allomyces, Blastocladiella, Neocallimastix. These genera represent genetically diverse groups. Although the research discussed here is restricted to a small sample,
some general conclusions can be reached about zoosporic fungi as a whole. Like many other eukaryotic microorganisms, zoosporic
fungi are sensitive to a large number of antibiotics, fungicides, surfactants, bacterial metabolites, metabolic poisons, proteins,
heavy metals and other antifungal substances. These include substances commonly released into the environment for the control
of plant and animal diseases, for increasing production of domestic animals and in the form of waste products from industry.
It is possible that the release of antifungal substances into the environment might cause significant changes in the community
structure of zoosporic fungi as well as of other groups of microorganisms which play significant roles in food web dynamics
and ecosystem complexity. However, this needs documentation by quantitative studies. For these reasons, extensive research
on the effects of antifungal substances is much needed. |
