Microcosm Study

چکیده
Abbott (1966) described microcosms as miniaturized ecosystems. Among the oldest and most specialized examples of the microcosm technique were bioassay systems, such as that found in the standard BOD determination. Abbott also noted that, due to the unpredictability and complexity of natural systems, in situ experiment results were often vague and inconclusive, and many researchers had successfully used microcosm systems to simplify experimental conditions in their investigations of natural systems. In addition, he noted that, although microcosms do not reproduce natural systems precisely, they provide the advantage of allowing researchers to investigate under controlled conditions.

Draft Guidance Document on Simulated Freshwater Lentic Field Tests (Outdoor Microcosms and Mesocosms)
1. Outdoor microcosms and mesocosms are useful in risk assessment when lower-tier and higher-tier laboratory studies (single-species and multi-species) indicate potential risks. They can be an important tool in bridging the gap between these studies and in attempting to understand and predict what may occur in the natural environment subjected to these risks. Every microcosm or mesocosm study s...

متن کاملSemicontinuous microcosm study of aerobic cometabolism of trichloroethylene using toluene.
A semicontinuous slurry-microcosm method was applied to mimic trichloroethylene (TCE) cometabolic biodegradation field results at the Que-Jen in-situ pilot study. The microcosm study confirmed the process of aerobic cometabolism of TCE using toluene as the primary substrate. Based on the nucleotide sequence of 16S rRNA genes, the toluene-oxidizing bacteria in microcosms were identified, i.e. Ra...
