A novel extracellular low-temperature active phytase from Bacillus aryabhattai RS1 with potential application in plant growth.

Bacillus aryabhattai RS1 isolated from rhizosphere produced an extracellular, low temperature active phytase. The cultural conditions for enzyme production were optimized to obtain 35 U mL of activity. Purified phytase had specific activity and molecular weight of 72.
