High-throughput screening for gene libraries expressing carbohydrate hydrolase activity.
A simple and fast method is described allowing screening of large number of Escherichia coli clones (4000 per day) for the presence of functional or improved carbohydrate hydrolase enzymes. The procedure is relatively cheap and has the advantage that carbohydrate degrading activity can be directly measured using liquid cultures grown in microtiter plates without the need of separation or purification steps.
