Abstract

Aspergillus tamarii IMI388810 (B) a tannic acid degrading fungus was isolated from soil inundated by effluent of a tannery at Oji River local Government Area of Enugu State, Nigeria. It was identified by
CABI Bioscience, United Kingdom as A. tamarii with accession number of IMI 388810 (B). This fungus produced tannase in a fermentation medium M containing tannic acid as the only carbon source. Time course of enzyme synthesis by the fungus showed that the enzyme production followed logarithmic growth phase with maximum enzyme yield being obtained after 6 days corresponding to the culture pH of 3.8.
