Other claims from this paper (15)
- Observation Wheat, barley and sorghum phytases had an optimal pH of 5.0.
- Observation Maize germ phytase had an optimal pH of 5.5.
- Observation Wheat and barley phytases had an optimal temperature of 55oC.
- Observation Sorghum and maize germ phytase had an optimal temperature of 50oC.
- Intervention effect Soaking and germination did not alter optimal phytase pH or temperature.
- Observation Phytase activity was maximal at 2.0 mM sodium phytate for wheat, barley and sorghum.
- Observation Maize germ phytase activity was maximal at 1.5 mM sodium phytate.
- Observation Phytase Km and Vmax varied among the 96 h germinated cereal grains.
- Observation Phytase activity declined beyond two hours incubation for wheat, barley and maize germ.
- Observation Sorghum phytase activity declined after more than one hour incubation.
- Intervention effect Added Ca2+ caused a smaller reduction in phytase activity than other metal ions.
- Intervention effect Other metal ions variably reduced cereal phytase activity.
- Intervention effect Wheat phytase activity increased 5.4-fold after 120 hours germination.
- Intervention effect Sorghum phytase activity increased 7.3-fold after 120 hours germination.
- Intervention effect Maize germ phytase activity increased 6.9-fold after 96 hours germination.
