Abstract

Inhibitory effects of an anti-microbial agent on a model activated sludge system were examined. Using microbial counts and14CO2 evolution from radiolabeled starch and cellulose, inhibitory effects of small concentration increments of HgCl2 could be monitored as could the rapid recovery of microbial viability after 24 h. Mercury dissipation accounted for part of this recovery but bacterial resistance to mercury is also implicated.
