This study analyzed the production of tannase by Aspergillus sp. GM4 under solid-state fermentation (SSF) using different vegetable leaves (mango, jamun and coff ee) and agricultural residu es (coffee husks, rice husks and wheat bran). Among the substrates used jamun leaves yielded high tannase production. The Plackett-Burman design was conducted to evaluate the effects of 12 independent variables on the production of tannase under SSF using jamun leaves as substrate. Among these variables, incubation time, potassium nitrate and tannic acid had significant effe cts on enzyme production. A lower incubation time was fixed and supplementation with potassium nitrate and tannic acid were optimized using the Central Composite Design. The best conditions for tannase prod uction were: incubation time of 2 days; tannic acid at 1.53% (w w -1 ) and potassium nitrate at 2.71% (w w -1 ). After the optimization process, tannase production increased 4.65-fold, which showed that the statistical ex perimental design offers a practicable approach to the implementation of optimization of tannase production. 2015 artículo científico 1679-9291 https://www.redalyc.org/articulo.oa?id=307239651004 en http://www.redalyc.org/revista.oa?id=3072 Acta Scientiarum.
