摘要：

A new cell immobilization technique using polyvinyl alcohol crosslinked with sodium nitrate was developed. This new technique can simultaneously eliminate the agglomeration of PVA beads and the toxicity of boric acid caused by the PVA-boric acid and PVA-orthophosphate methods. Alcaligenes eutrophus was immobilized using four different PVA entrapment processes. The stability, swelling, relative mechanical strength and denitrification activity of the PVA beads were compared in this study.
