Isolation of Aspergillus niger from three varieties of Bambara nuts for simultaneous production of phytase and tannase

The aim of this work was to isolate strain of Aspergillus niger for simultaneous production of phytase and tannase enzymes. In this study, A. niger strains were isolated from Bambara nuts (Vigna subterranea) of three different color seed coats. Growth of colonies in plates with tannic acid and phytic acid sodium salt-containing media indicate their ability to synthesize both enzymes. The strain...
