Abstract
Acclimation of microbial communities exposed to p-nitrophenol (PNP) was measured in laboratory test systems and in a freshwater pond. Laboratory tests were conducted in shake flasks with water, shake flasks with water and sediment, eco-cores, and two sizes of microcosm. The sediment and water samples used in the laboratory experiments were obtained from the pond. After a 6-day acclimation period, PNP was biodegraded rapidly in the pond. When the pond was treated with PNP a second time, biodegradation began immediately. The acclimation periods in laboratory test systems that contained sediment were similar to that in the pond. The acclimation period was threefold longer in shake flasks without sediment. PNP was biodegraded more slowly by microbial communities acclimated in the laboratory than it was in the pond, and the rate of biodegradation varied with the type of test. The number of bacteria able to mineralize PNP increased by 3 orders of magnitude in the pond during the acclimation period. Similar increases accompanied acclimation in the laboratory systems.
