In 25 strains a low phytase activity, 0.10 – 0.62 μmol phosphate released per min per mg protein, was found. High activity (2.61 μmol/min per mg protein) was found in the strain identified as Enterococcus hirae. Phytase activity was cell associated, being higher in the cell extract than in the cell walls. Extracellular phytase activity and cell-associated phosphatase activity were not detected. Phytase activity was optimal around pH 5.0. Other bacteria with a high phytase activity may be present in the rabbit caecum but remain to be identified.
