Inhibition of inter-microbial predation by chlorinated hydrocarbons

ABSTRACT TIDAL or estuarine regions have traditionally served as sinks for municipal sewage. Some microbial predators in the sea feed on the enteric bacteria contained in such sewage1.

Recently, the concentration of chlorinated hydrocarbons in the sea, especially in estuarine regions, has increased although it remains considerably below the concentration which directly

affects the viability of predators or intestional pathogens. But, estuarine chlorinated hydrocarbon concentrations are within a factor of 20 of those which we have observed to inhibit the

chemotactic response of marine bacteria2. Because bacterial predators are chemotactic specifically to exudates of their prey3, inhibition of chemotaxis by chlorinated hydrocarbons may

directly affect estuarine self-purification rates. We report here the impact of two chlorinated hydrocarbons, at concentrations observed to inhibit chemotaxis4, on enteric bacteria

predation. Access through your institution Buy or subscribe This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your institution Subscribe to
