Short Communication


An organophosphate-degrading soil isolate of Pseudomonas sp. A3, immobilized at 5% (wet wt/v) cell mass in 3% (w/v) sodium alginate beads, detoxified 99% of 1 mm methylparathion in 48 h. The beads were re-usable for five batches, the sixth batch only giving 73% methylparathion removal.
