Trametes versicolor laccase oxidation of gallic acid toward a polyconjugated semiconducting material

This study is concerned with the successful synthesis of a semiconducting polyphenol in high yield (82%) from Trametes versicolor laccase-mediated oxidative polymerization of the naturally abundant gallic acid. The determined KM was 0.418 mM, thus showing high affinity of this enzyme for the substrate. The polymer can be solubilized in water up to 150 mg mL−1, whereas it presents poor solubility in organic solvents. The molecular structure...
