Study of Complexes of Tannic Acid with Fe(III) and Fe(II)

open access: yesJournal of Analytical Methods in Chemistry, 2019
UV-Vis absorption spectra of tannic acid were gained at pH 1.0∼9.0. Due to the pH value dependence of complex, the stoichiometry of tannic acid with iron ions was tested in buffer solution by the mole ratio method.

Identification of a Conserved Transcriptional Activator-Repressor Module Controlling the Expression of Genes Involved in Tannic Acid Degradation and Gallic Acid Utilization in Aspergillus niger

open access: yesFrontiers in Fungal Biology, 2021
Tannic acid, a hydrolysable gallotannin present in plant tissues, consists of a central glucose molecule esterified with gallic acid molecules. Some microorganisms, including several Aspergillus species, can metabolize tannic acid by releasing gallic ...

Evaluating the Toxic Effects of Tannic Acid Treatment on Hyphantria cunea Larvae

open access: yesInsects, 2022
Simple Summary The high concentration of tannic acid in the needles of larch, a non-host plant, was inferred to be the root cause of the antifeedant activity displayed by Hyphantria cunea towards larch needles.

Silicic Acid-Mediated Formation of Tannic Acid Nanocoatings [PDF]

open access: yesLangmuir, 2019
Tannic acid (TA) adheres to a broad variety of different materials and forms versatile surface coatings for technical and biological applications. In mild alkaline conditions, autoxidation processes occur and a firm monolayer is formed. Up to now, thicker coatings are obtained in only a cross-linked multilayer fashion.
