The Influence Of Salinity Concentration On Power Generation And Microbial Viability In Deep Sea Sediment Microbial Fuel Cells

---

The deep-sea ecosystem is a largely unexplored environment with unique chemical and physical
conditions that impact the organisms living there. Deep-sea sediments contain a diverse population
of electroactive bacteria (EABs) that have the potential to generate electricity in microbial fuel cells
(MFCs). This study aims to investigate the influence of salinity concentration on bacterial viability and
power generation in deep-sea sediment microbial fuel cells (SMFCs). Three deep-sea SMFCs with
different salinity concentrations (33 g/L, 35 g/L, and 38 g/L) were constructed and evaluated for their
current density, power density, and electrochemical impedance spectroscopy (EIS). Viable cell
enumeration techniques were employed to quantify the remaining live cells, and cell morphology
was observed through microscopy. The power density decreased with increasing salinity, and the
internal resistance of the deep-sea SMFCs increased with higher salinity. Highest current density and
power density was found at salinity concentration of 33 g/L at 240.6547 mA/m
