The study includes several perspectives:

1. feasibility assessment upon production of functional chemical contents in herbal extracts via electro-fermentation;
2. electrochemical performance evaluation of bioenergy extraction using medicinal herbs;
3. maximal electroactive expression of microalgal metabolites in microalgal and bacterial cocultures for value-added production;
4. treatability study of using polyphenolics content or different electrochemically active species for electro-fermentation;
5. abiotic treatment upon recalcitrant or non-biodegradable chemicals by advanced oxidation (e.g., electro-oxidation).
