Thiobacillus thioparus, Azotobacter chroococcum, Rhizobium leguminosarum, Aspergillus niger, Paramecium caudatum, Colpidium sp., and a mixed culture of soil ciliates were not adversely influenced nor stimulated by the presence of dimethyl 2,3,5,6-tetrachloroterephthalate (DCPA). Soil from plots treated 7 years at 5.0 ppm showed no accumulation of DCPA. Plate counts of actinomyces, bacteria, and molds from field and laboratory-treated soils showed no adverse effect. A mixed culture of soil algae and fungi grew significantly more in the presence of DCPA.
