Sulfur-rich deposits associated with the deep submarine volcano Fani Maore support broad microbial sulfur cycling communities.

ABSTRACT:

Background

In 2018, the island of Mayotte located in the western Indian ocean, has experienced a seismo-volcanic crisis linked to the birth of an impressive intraplate submarine volcano at the east of the island. This volcano, named Fani Maoré, which has not yet been the subject of microbiological studies, triggered the largest submarine eruptive event ever recorded. Close to the volcano's summit is a singular meter-size structure containing abundant native sulfur mineralizations. While a wide variety of ecosystems, with more or less well documented microbial communities, are found in active volcanoes on the ocean floor, knowledge on microbial communities hosted in habitats such as sulfur-rich intraplate volcanoes, that are not located on hotspots, remains limited.
