“…The available informnation relating to PCB and PHE stress on heterotrophic bacterial pop-ulation indicates variable, but minor, stress effects. In examining the effects of PCB on pure cultures of environmental isolates, PCB has demonstrated both inhibitory and stimulatory effects (6,7,20,27). In a sense, this investigation supports both types of observations.…”

“…Others have shown that PCBs inhibited growth ofselected pure cultures ofbacteria when added to liquid growth medium (2). Sensitivity of bacteria at PCB concentrations lower than 1 mg/liter (1 ppm) has not commonly been reported, however, and information concerning the physiological basis of PCB toxicity in bacteria is meager.…”

A number of marine bacterial isolates from both near-shore and open-ocean environments were tested for growth inhibition with exposure to low concentrations (1 to 100 ,ug/liter) of Aroclor 1254, a commercial mixture of polychlorinated biphenyls (PCBs). Of over 17 bacterial cultures tested, growth of only two openocean isolates, one a pseudomonad and the other a tetrad-forming coccus, was consistently inhibited by Aroclor at concentrations as low as 10 ,ug/liter (10 ppb). Growth inhibition was dose dependent over a concentration range of 10 to 100

“…The relationship between increasing organic toxicant concentration and lag time has been observed in bacterial species capable of biodegrading other compounds. These include bacterial species capable of degrading p-nitrophenol (Wiggins and Alexander 1988), polychlorinated biphenyls (Bourquin and Cassidy 1975), and a variety of agricultural pesticides (Parker and Doxtader 1982;Lappin et al, 1985). The lag time noted prior to observable degradation is believed to be a function of both the time required for acclimation and the accumulation of sufficient microbial biomass to obtain measurable rates (Topp et al, 1988).…”

The effects of chromium (or chromate, as supplied by CrO3) on a pentachlorophenol‐degrading Flavobacterium sp. (ATCC 53874) were examined in a liquid bacterial growth medium. Cr6+ concentrations ⩾ 5.0 μg mL−1 caused the complete inhibition of bacterial growth. The EC25, EC50, and EC75 calculated after 96 h of incubation were 0.44, 1.44, and 3.82 μg mL−1, respectively. Cr6+ caused an irreversible reduction in total cell yield during the 21‐day incubation. Cr6+ also elicited an increase in the lag time recorded before there was measurable pentachlorophenol (PCP) degradation by this bacterium. There was also an increase in the overall time required for complete degradation of PCP to nondetectable levels. A similar response was noted with all PCP concentrations examined from 10 to 100 μg mL−1. However, a more pronounced response occurred at the lower PCP concentrations. The significance of these data relative to the in situ use of PCP‐degrading bacteria for site bioremediation is outlined. © 1994 by John Wiley & Sons, Inc..

Effect of Polychlorinated Biphenyl Formulations on the Growth of Estuarine Bacteria1

Abstract: Polychlorinated biphenyl formulations inhibited the growth of certain estuarine bacteria. The sensitive strains, although exhibiting some similar physiological characteristics, contained both gram-positive and gram-negative bacteria.
