Abstract

Insoluble enzymatically active particles are produced by forming an intimate mixture of a jellifying protein such as gelatin and microbial cells containing an enzyme such as glucose isomerase, passing the mixture through a die to produce threads, passing the threads into cold water to jellify the threads, contacting the jellified threads with a crosslinking agent and cutting the resultant crosslinked threads into pieces.
