✦ Synopsis


Penicillium variabile P 16 immobilized on polyurethane sponge produced gluconic acid in presence of rock phosphate, the latter being simultaneously solubilized during five repeated batches. A total production of 42, 60, and 90 g gluconic acid/l was obtained for 3, 7, and 14 g rock phosphate/l, respectively. Accordingly, soluble phosphorus concentration increased with gluconic acid production, reaching a maximum of 350 mg/l at the 3d batch in medium supplemented with 14 g rock phosphate/l.
