“…This reflects that the sedimentary organic matter in the deeper layers is electrochemically active due to oxidative degradation and natural bioturbation [12]. In the mangrove-covered zone, this degradation may occur through hydrolysis or bacterial respiration, which may be enhanced by oxygenation produced by the mangrove rhizosphere [29][30][31]. In the mudflat zone, the organic matter degradation may be facilitated by oxygenation driven by tidal and hydrological regime energies in this study area [8,21].…”

In order to determine the organic matter redox state in relation to specific sources in mangrove sediments, two 60 cm-long sediment cores were collected from mangrove-covered and mudflat zones within a mangrove forest in Peru. Sediment subsamples from these cores were analyzed to determine δ13C values and C:N ratios, whereas two redox indices, namely, electrochemical (fEAOM) and spectroscopical (A1650/A3400) indices, were taken from a previous study and correlated with the geochemical indices obtained from this work. These indices may provide accurate information on sedimentary organic matter diagenesis by oxidative processes through its redox state. The results show that the electrochemical index (fEAOM) and the spectroscopical index (A1650/A3400) for mangrove-covered sediments exhibited a positive correlation with δ13C values and a negative correlation with C:N molar ratios. These correlations suggest that the more labile sedimentary organic matter derived from non-terrestrial sources is in a more oxidized state than that derived from mangrove vegetation. However, this was not valid for mudflat zones, where non-significant correlations between geochemical indices were observed. Furthermore, the results suggest that the redox state of the organic matter deposited over time is dependent on source mixing influences, being better preserved in the presence of mangrove-derived organic matter.

“…Several EAB strains have been identified in a large variety of natural ecosystems such as marine sediments, soils, seawater, fresh water, domestic and industrial wastewater [20], activated sludge and sewage sludge [21]. Further other sources have been also reported as garden compost [22], manure [23], wetland [24] and mangrove [25]. All these ecosystems can be used as sources of primary inoculum for selection and isolation of EAB.…”
