Abstract
In this paper, a simple and effective method using sodium metasilicate as precursor and amine as additive was first reported to immobilize recombinant nitrilase, for efficient production of 2-hydroxy-4-(methylthio) butanoic acid from 2-hydroxy-4-(methylthio) butanenitrile. High immobilization recovery of enzyme activity (above 90 %) was achieved. The immobilized enzyme displayed better thermal stability, pH stability and shelf life compared to free nitrilase. Moreover, it showed excellent reusability and could be recycled up to 16 batches without significant loss in activity. 200 mM 2-hydroxy-4-(methylthio) butanenitrile was completely converted by the immobilized enzyme within 30 min, and the accumulation amount of 2-hydroxy-4-(methylthio) butanoic acid reached 130 mmol/g of immobilized beads after 16 batches. These encouraging results demonstrated the efficiency of the new technology for nitrilase immobilization, which has great potential in preparation of 2-hydroxy-4-(methylthio) butanoic acid.
