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.
