Biotechnology and Bioengineering, 1974
AbstractThe enzyme tannase has been immobilized on an inorganic support by covalent attachment. This immobilized enzyme was characterized and half‐lives determined. Since this enzyme has application in the treatment of tea cream, experiments were also carried out to determine the effect of tea on enzyme half‐life.

Tannase production by Paecilomyces variotii
Bioresource Technology, 2007Surface response methodology was applied to the optimization of the laboratory scale production of tannase using a lineage of Paecilomyces variotii. A preliminary study was conducted to evaluate the effects of variables, including temperature ( degrees C), residue (%) (coffee husk:wheat bran), tannic acid (%) and salt solutions (%) on the production of

Purification and characterization of tannase and tannase gene from Enterobacter sp.
Process Biochemistry, 2011Abstract Tannase of Enterobacter sp. was purified and characterized at molecular level. It was found to be 90 kDa in molecular weight. The purified enzyme showed maximum activity at 40 °C. The enzyme was also found to be active in acidic range of pH.

Spectrophotometric assay of tannase
Phytochemistry, 1970Abstract The synthesis of the o, m and p-nitrophenyl esters of gallic acid and 3-O-methylgallic acid is described. The use of the p-nitrophenyl esters as substrates in a spectrophotometric assay of the enzyme tannase is described.

Tannases: Production, properties, applications
Biocatalysis and Agricultural Biotechnology, 2018Abstract Microbial tannases are industrially important enzymes belong to the family of esterases which catalyze the generation of gallic acid and glucose by the degradation of polyphenolic compounds such as tannins. In spite of wastewater treatment and gallic acid production, tannases have wide application in the processing of food, beverage and ...

Applied Microbiology and Biotechnology, 2006
An extracellular tannase (tannin acyl hydrolase) was isolated from Paecilomyces variotii and purified from cell-free culture filtrate using ammonium sulfate precipitation followed by ion exchange and gel filtration chromatography. Fractional precipitation of the culture filtrate with ammonium sulfate yielded 78.7% with 13.6-folds purification, and ...

Crystal Structure of Tannase from Lactobacillus plantarum
Journal of Molecular Biology, 2013Tannins are water-soluble polyphenolic compounds in plants. Hydrolyzable tannins are derivatives of gallic acid (3,4,5-trihydroxybenzoic acid) or its meta-depsidic forms that are esterified to polyol, catechin, or triterpenoid units. Tannases are a family of esterases that catalyze the hydrolysis of the galloyl ester bond in hydrolyzable tannins to ...

Novel Trends for Use of Microbial Tannases
Preparative Biochemistry and Biotechnology, 2014Tannases, mainly produced by microorganisms, are able to hydrolyze gallotannins, ellagitannins, complex tannins, and gallic acid esters into gallic acid, ellagic acid, glucose, or alcohols, and also synthesize gallic acid esters using tannic acid or gallic acid with a variety of alcohols in nonaqueous media.

Tannase production by Bacillus licheniformis
Biotechnology Letters, 2000Bacillus licheniformis KBR 6 produced maximum extracellular tannase activity at 0.21 U ml−1 with 1.5% (w/v) tannic acid either in the absence or presence of glucose (1 g l−1) after 18–21 h growth though the organism did not attain maximum growth until 36 h.
