Rapid assay for amidohydrolase (urease) activity in environmental samples

The use of microplate technology for enzyme assays has made it economical to measure a wide range of activities in environmental samples. Urease is one of the most widely measured soil enzyme activities, but current methods are cumbersome. We have developed a rapid, safe and sensitive assay that can be performed on microplates.
