A granular enzyme composition is produced, having reduced tendencies to form dust and leave residue, and exhibiting improved stability and delayed release characteristics. The granular composition comprises a core, an enzyme layer and an outer coating layer. The enzyme layer, and optionally the core and outer coating layer, contain a vinyl polymer. The vinyl polymer is preferably a hydrolyzed polyvinyl alcohol or copolymer thereof. The hydrolyzed polyvinyl alcohol has varying degrees of hydrolysis in the core, enzyme layer and outer coating layer. Also disclosed are methods for making such enzyme-containing granules, the methods having greatly reduced processing time.

The invention relates to use of a water dispersible isophthalic acid polymer as a dust free coating on particulates. The particles provide a timed release of the contents of the particle which allows for reduced amounts of active agents on the coatings and less interference between active agents in the coating or environment and the particulates.

Disclosed are methods for the recovery and purification of naturally produced chymosin. In particular, disclosed are methods for the recovery and purification of chymosin from aqueous solutions containing chymosin, pepsin and other contaminants.

Processes for the recovery of naturally produced chymosin

Disclosed are methods for the recovery of microbially produced chymosin. In particular, disclosed are methods for the recovery of chymosin from the fermentation beer arising from culturing microorganisms which have been engineered so as to produce chymosin. Also disclosed are methods for the selective recovery and subsequent purification of microbially produced chymosin.
