Silica glass-entrapped lipase was prepared by the sol-gel method using tetramethoxysilane, and its esterification activity in n-hexane was examined for isoamylbutyrate formation. The hydrogel preparation containing a large amount of water exhibited enough activity. Although the activity of xerogel-e

The sol-el fi method, usin 6 a mixture of tetramethoxysilane (TMOS) and methyltrimet ox P silane (MTrM S) as the silicon alkoxide precursor, has been applied to entrapment o lipase catalyzing esterification reactions in organic media. Increasing molar ratio of MTrMOS to TMOS led to formation of opaq
## Abstract Die Methode zur Bestimmung der Carbamate basiert auf der die AktivitΓ€t von Acetylcholinesterase hemmenden Wirkung dieser Stoffe. Die Verwendung von radioaktiv markiertem Acetylcholin als Substrat, die anschlieΓende extraktive Abtrennung der hydrolytisch gebildeten radioaktiven EssigsΓ€ur
