“…These data are in accordance with the results obtained in this work, but the enzymatic activities obtained in this study were relatively higher than those reported by Batra and Saxena (2005) [22] and [23]. According to Aguilar et al (2007) [4], tannases are induced and expressed at different levels, with patterns of production depending on the strain and cultivation conditions.…”

“…There was no relationship between the enzyme activity observed for SmF and the diameter of hydrolysis of tannic acid in the plate assay. Similar results were observed by Batra and Saxena (2005) [22], when analyzed the production of tannase by Aspergillus acolumaris. [23] reported the importance of checking the results obtained through the plate assay to minimize the loss of microorganisms which had good production of tannase under SmF and recommended the association of the quantitative selection with the plate assay.…”

“…Batra and Saxena (2005) [22], studied the potential of this enzyme production by fungi belonging to the genera Aspergillus and Penicillium. The authors observed that A. niger produced hydrolysis halo of tannic acid with 21 mm of diameter and an enzymatic activity of 1.65 U/mL, while A. fumigatus presented halo of hydrolysis with 65 mm of diameter and activity of 8.65 U/mL after 24 h of cultivation.…”

Tannin acyl hydrolase (EC 3.1.1.20), called tannase, is an enzyme of great biotechnological interest for applications in food, chemical, beverage and pharmaceutical industries. Therefore, the objective of this study was to isolate, select and identify strains of endophytic fungi from rich tannin plants collected in the Caatinga, as well as, the optimization of culture conditions for the best producers. Sixteen endophyte fungi were isolated from the barks of mastic (Myracrodruon urundeuva Allemão), angico (Anadenanthera colubrina Vell.), barauna (Schinopsis brasiliensis Engl.), cajueiro (Anacardium occidentale L.) and catingueira (Caesalpinia pyramidalis Tul). All strains showed ability of using tannic acid as carbon source. The species A. niger and A. fumigatus isolated from angico and cajueiro, respectively, presented the highest enzyme production. The optimum conditions for the production of tannase by A. niger were 24 h cultivation in Khanna medium containing 2% tannic acid, in the absence of nitrogen source, at 37 °C. A. fumigatus showed increased production of tannase when cultured in mineral medium for 24 h using 2% tannic acid as carbon source and peptone as additional nitrogen source, at 37 ºC. The optimum apparent temperature and pH of activity for the enzymes produced by both fungal species were 30 ºC and 4.0, respectively.

A biochemical characterization of the tannase from a Paecilomyces variotii strain isolated in São Paulo, Brazil was carried out. Paecilomyces variotii is a strain obtained from the screening of five hundred fungi that were tested for their production of tannase. The enzyme produced was partially purified using ammonium sulfate precipitation followed by ion exchange chromatography, diethylaminoethyl (DEAE)-Sepharose. Effects of temperature and pH on the activity of crude tannase crude and purified tannase was studied. K m was found to be 0.61 µmol and V max = 0.55 U/mL. Temperature of 40 to 65ºC and pH 4.5 to 6.5 were optimum for tannase activity and stability; it could find potential use in the food-processing industry. The effects of different inhibitors, surfactants and chelators on the enzyme activity were also studied.

“…Tannase is also used in the preparation of instant tea, wine, beer and coffee-flavored soft drinks and also as additive for detannification of food. Many fungi, such as Aspergillii, Penicillii, Fusaria, and Trichoderma [3][4][5][6] as well as yeast like Candida sp., and Saccharomyces cerevisiae [7] have been reported to be tannase producers. On the other hand, few bacteria are known to produce tannase and include certain species of Bacilli, Corynebacterium sp., Lactobacillus sp., and Serratia sp., [8,9].…”

Abstract:A study on optimization of submerged fermentative production of tannase by Aspergillus niger was carried out. Aspergillus niger (MTCC 3557) was used for maximum production of Tannase enzyme and the factors affecting the production were optimized. The optimum conditions for maximum tannase enzyme production in the Submerged Fermentation (SmF) using Aspergillus niger was obtained with an initial tannic acid concentration of 3% (w/v) at 35°C, Initial pH of 5.5 and a fermentation period of 96h.The substrates Betalnut husk and Plantain flower gave a maximum tannase production of 19.3 U/ml and 17.89 U/ml respectively.
