Abstract
Alcaligenes eutrophus was successfully recovered from high cell densit y broths by pre-treatment with polyaluminium hydroxide chloride silica te as a coagulant at 36 - 90 mg Al/l. The optimum pH range for cell co agulation was 10-12. Subsequent centrifugation (45 x g) and filtration (pore size 0.5 mm) gave a cell recovery of higher than 90%. The energ y demand for cell recovery with the coagulant was only 3-11% of that w ithout it.
