To understand sulfuric acid speleogenesis (SAS) it is of upmost importance to know how fast H2S is oxidised to sulfuric acid by bacteria when the upwelling water rich in H2S encounters water from the surface that contains oxygen. It is also important to know where this happens and what are the concentrations ofH2S in the upwelling waters. It is possible that bacteria exist in narrow fracture with about a few hundred µm aperture width?

and Ilenia D'Angeli of Univ. Bologna
Bacteria are strongly involved for sure.
Dreybrodt Wolfgang ,
Regards from Spain, I hope that you are well!!
We are working in the presence of bacteria in hypogenic caves fault-related with a low value of atmospheric oxygen and a high concentration of CO2 inside. We are in an initial state but working in the role of bacteria in this environment. I have attached our last work of the role of methane, which is directly related to the activity of bacteria in these places, and the role in the hypogenic speleogenisis. We have recognized some species of archaea and bacteria. I will contact you with one of our PhD student (Tamara Martin) and his advisor with your question. Also, I have attached our last congress abstract sent to the missed EGU.
Best regards
