PINTO, Gustavo A.S.; LEITE, Selma G.F.; TERZI, Selma C.  and  COURI, Sonia. Selection of tannase-producing Aspergillus niger strains. Braz. J. Microbiol. [online]. 2001, vol.32, n.1, pp. 24-26. ISSN 1517-8382.  http://dx.doi.org/10.1590/S1517-83822001000100006.

The aim of this work was to select strains of Aspergillus niger for tannase production. Growth of colonies in plates with tannic acid-containing medium indicated their ability to synthesize tannase. Tannase activity was also measured in solid-state fermentation. A. niger 11T25A5 was the best tannase producer (67.5 U.g^-1/72 hours of fermentation).

Keywords : tannase; Aspergillus niger; screening solid-state; fermentation.
