The effect of DDT and PCB on lipid metabolism in E. coli and B. fragilis

E. Coli and bacteroides fragilis, principal human enteric aerobic and anaerobic bacteria, were cultured with suitable controls in the presence of .01 and .10 ppm of DDT and PCB. DDT increased E. Coli growth at the .01 level, but had no detectable effect at .10 ppm. Total lipid content was not signif...

Description
Summary:E. Coli and bacteroides fragilis, principal human enteric aerobic and anaerobic bacteria, were cultured with suitable controls in the presence of .01 and .10 ppm of DDT and PCB. DDT increased E. Coli growth at the .01 level, but had no detectable effect at .10 ppm. Total lipid content was not significantly altered by either DDT or PCB. DDT at .01 ppm depressed B. Fragilis growth, but had no significant effect on lipid levels. PCB increased B. Fragilis growth at the .10 ppm level, but significantly depressed lipid synthesis at both concentrations.
