Interactions Between DDT and River Fungi

Abstract

Concentrations of p,p'-DDT between 0.1 and 60 mug/ml enhanced the growth rate of Heliscus submersus, and concentrations greater than 2 mug/ml had a similar effect on Tetracladium setigerum, Varicosporium elodeae, and Clavariopsis aquatica. The rate of growth of each fungus increased with increased DDT concentration.
