[The viability of species of microscopic fungi in nitrate-polluted water].

It has been found out, that contamination of marine and river water and soil with nitrates significantly influence the viability of microscopic fungi living there. This influence was positive when the nitrates content was moderate (from 0.2 to 2 g/l), extremely high concentrations of nitrates (20 g/l) lead to the inhibition of fungi growth and to their death.
