Inositol Phosphate Phosphatases of Microbiological Origin. The Isolation of Soil Bacteria Having Inositol Phosphate Phosphatase Activity

Abstract

The isolation of three soil bacteria exhibiting inositol phosphate phosphatase activity is described. One isolate, a member of the genus Pseudomonas, had pronounced phytase activity but the others had not. The latter were slightly active against pentaphosphates, however, and they easily dephosphorylated tetraphosphates and lower esters.
