Abstract

Exploring optimal supplement strategy of polyphenolics-abundant herbal extracts for bioenergy stimulation in microbial fuel cells

Bor-Yann Chen

This sequential examination uncovered the ideal technique to enhance concentrates of polyphenolics plentiful restorative spices and Camellia tea as electron transports (ESs) for invigorating bioenergy age in microbial energy units (MFCs). Apparently, Camellia sinensis (L.) Kuntze and Syzygium aromaticum were promising electroactive ESs. Moderate temperature (ca. 65°C) and slightly alkaline pHs (~10) were electrochemically feasible conditions for herbal extraction. Ideal substance of polyphenolics rich spices and tea removes with maximal electrochemical exercises could be steadily acquired. Force thickness of MFC enhanced with Camellia green tea concentrate could fundamentally build ca.176%, suggesting that unfermented green tea extract would be the most appropriate ESs. As correlation analysis indicated that total phenolic contents and electron shuttling capabilities were all electrochemically associated. Also, compound structure is emphatically influenced whether cancer prevention agent exercises of polyphenolics bountiful home grown concentrates could be reversibly changed to be electron transporting capacities (e.g., replacement designs). Dihydroxyl substiutuents of ortho or para to one another were likely encouraging for electron-transporting, yet not for meta substituents. In addition, bioelectrochemical treatment upon therapeutic home grown concentrates (e.g., cyclic electron giving and pulling back procedures) may give an electroactive choice to weaken natural biotoxicity to completely communicate bioenergy-carrying exercises in applications (e.g., bioenergy extraction and home grown drug).
