Antibacterial and antioxidant polyphenols-chitosan agents have been elaborated through the adsorption of green tea and black tea extracts into chitosan. Their incorporation leads to an enhancement of the inhibitory effect of the biopolymer against the gram-negative and gram-positive bacteria. Voltammetry at a rotating disk electrode reveals a difficulty of the reduction of oxygen in the presence these complexes.

Abstract


Antibacterial and antioxidant polyphenols-chitosan agents have been elaborated through the adsorption of green tea and black tea extracts into chitosan. Their incorporation leads to an enhancement of the inhibitory effect of the biopolymer against the gram-negative and gram-positive bacteria. Voltammetry at a rotating disk electrode reveals a difficulty of the reduction of oxygen in the presence these complexes.
