Project: Coupling of carbonate cycling and redox reactions in the bioturbated zone of marine sediments (Carbonate cycling bioturbated zone)


Abstract

In this study, we examine cable bacteria metabolic activity and growth dynamics using the functional expression of net electrogenic activity revealed by pH patterns, inferred reaction rate distributions, and filamentous cell abundance. We demonstrate in experimental microcosms, the potential for substantial cable bacteria activity in Mn- and Fe-depleted carbonate muds from Florida Bay, USA, and document their biogeochemical impacts in the near absence of Mn and Fe.

The detailed data plot figures are given in Yin, H., Aller, J.Y., Furman, B.T., Aller, R.C., and Zhu, Q. (2022).  Cable bacteria activity and impacts in Fe and Mn depleted carbonate sediments.  Marine Chemistry 246, 104176.  doi.org/10.1016/j.marchem.2022.104176
