However, when this gallotannin, a polymeric phenol, is attacked by tannase produced through enzymatic activity by native plants and rhizospheric microbes, toxic gallic acid is produced and released in the root zone, exacerbating the invasive Phragmites' noxiousness.
Alternatively, gallic acid can be produced by the microbial hydrolysis of tannic acid by tannase (tannin-acylhydrolase B 3.
This early colonization of fungi in tannin-rich mangrove leaves may be due to the fact that the fungi like Aspergilli are capable of producing tannase enzyme to degrade tannin (William et al.
An Aspergillus protein or enzyme known as tannase breaks down the tannin and unlocks the gallic acid.
