Abstract

The invention provides a composite catalyst containing rhodococcus fermentation broth and application thereof.The composite catalyst comprises the rhodococcus fermentation broth and a component A. The component A is selected from one or more of glycerin, glutaraldehyde, gelatin, methylparaben and polyethylene glycol. According to the composite catalyst, the storage stability of a single rhodococcus whole-cell catalyst can be remarkably improved, so that the single rhodococcus whole-cell catalyst can still maintain relatively high catalytic activity after being stored for a long time, and the problem that the production cost is increased due to inactivation of the catalyst is effectively solved.
