Do marine bacteria degrade. alpha. -hexachlorocyclohexane stereoselectively
- Univ. Hamburg (West Germany)
The enantiomeric ratio of a chiral organic pollutant has been determined gas chromatographically for the first time at low concentrations as encountered in a North Sea water sample by using heptakis (3-O-butyryl-2,6-di-O-pentyl)-{beta}-cyclodextrin as a chiral stationary phase. As an example, the separation of the enantiomers of {alpha}-hexachlorocyclo-hexane ({alpha}-HCH) is shown herein. However, the method is expected to be generally applicable to many environmental problems that are related to chiral biogenic and anthropogenic substances and chiral degradation products. The potential of this experimental approach for a discrimination between enzymatic and nonenzymatic processes in marine and terrestric ecosystems is discussed.
