Smart fungus - Pythium oligandrum
Pythium oligandrum is a microscopic fungus that was documented between the years of 1930–1932 by American scientist Charles Dreschler. In 1965, effective strains of Pythium oligandrum were isolated from the soil by Czech scientist Dasa Vesely, who dealt mainly with plant protection.
Pythium oligandrum parasitically consumes other microscopic fungi and uses them for its maintenance and survival. Pythium oligandrum penetrates it's parasitic hyphae into the microorganism and deposits nitrogen, carbon and sterols for use in its own reproduction process.
Due to its specific characteristics, this organism is classified in the kingdom Chromista–Stramenopila. Pythium oligandrum produces zoosporangia containing 8 to 40 moving zoospores that actively seek parasitic fungi.
Besides formation of fungal filaments and characteristic spiny-walled oospores, Pythium oligandrum produces different enzymes during its metabolism. Enzymes are primarily aimed at facilitating the penetration of hyphae into the fungal microorganisms. The moment Pythium oligandrum has nothing left to feed on it becomes dormant without sustenance for its survival.
