Abstract Tannin acyl hydrolase as the common name of tannase is an inducible extracellular enzyme that causes hydrolysis galloyl ester and depside bonds in tannins, yielding gallic acid glucose. The main objective this study to find a novel produced by Acinetobacter Baumannii . A number optimization steps were followed order improve highest production tannase. In present study, A. baumannii iso...

Introduction and Aim: Tannase an inducible extracellular microbial enzyme is extensively produced by different fermentation techniques finds wide applications in food, pharmaceutical textile industries. The present investigation focused on tannase production from Aspergillus niger through submerged (SmF) solid-substrate (SSF) using media. was also induced tamarind seeds. Methods Materials: grow...

Extracellular tannase and gallic acid were produced optimally under submerged fermentation at 37 (0)C, 72 h, pH 5.0, 10 %(v/v) inoculum and 4 %(w/v) of the agroresidue pomegranate rind (PR) powder by an Aspergillus niger isolate. Tannic acid (1 %) stimulated the enzyme production by 245.9 % while with 0.5 % glucose, increase was marginal. Tannase production was inhibited by gallic acid and nitr...

The effects of phytase and tannase enzyme treatment sorghum-based broiler diets on ileal villi characteristics were evaluated in Cobb 500 broilers. A total three sorghum levels, 0, 50, 100%, with 4 levels; 5% phytase, phytase+tannase combination used to develop 12 different dietary treatments. Three hundred sixty broilers randomly allocated the treatments a completely randomized design experime...

The faeB gene encoding a second feruloyl esterase from Aspergillus niger has been cloned and characterized. It consists of an open reading frame of 1644 bp containing one intron. The gene encodes a protein of 521 amino acids that has sequence similarity to that of an Aspergillus oryzae tannase. However, the encoded enzyme, feruloyl esterase B (FAEB), does not have tannase activity. Comparison o...
