S ummary Out of sixteen trace elements tested for the growth of this fungus, only Fe, Zn and Mn are found essential whereas the rest of the trace elements are not found essential for its growth. The fungus requires an optimum concentration of 1–10 ppm Fe and Zn and of 100 ppm Mn for its growth. Concentrations of the essential trace elements beyond the optimum level inhibit the growth of this fungus progressively. However, 200 ppm Zn completely inhibits the growth of this fungus.
