Summary

Alginate entrapped Pseudomonas denitrificans have been compared with cells confined in the outer space of a hollow-fiber membrane unit with respect to continuous denitrification of water. The hollow-fiber unit had a higher productivity as well as a stability similar to that of the alginate unit. A reduction of cell-leakage in the eluate was found in the hollow-fiber unit. The nitrogen gas produced could be removed by circulating the cell containing fluid over a hydrophobic membrane.
