Deep-sea sponge grounds as nutrient sinks: Denitrification is common in boreo-Arctic sponges
Rooks, Christine; Fang, James Kar-Hei; Mørkved, Pål Tore; Zhao, Rui; Rapp v/dødsbo, Hans Tore; Xavier, Joana R; Hoffmann, Friederike (Journal article; Peer reviewed, 2020-03)Sponges are commonly known as general nutrient providers for the marine ecosystem, recycling organic matter into various forms of bioavailable nutrients such as ammonium and nitrate. In this study we challenge this view. ... -
Indigenous Ammonia-Oxidizing Archaea in Oxic Subseafloor Oceanic Crust
Zhao, Rui; Dahle, Håkon; Ramírez, Gustavo A.; Jørgensen, Steffen Leth (Journal article, 2020-03-10)Oceanic ridge flank systems represent one of the largest and leastexplored microbial habitats on Earth. Fundamental ecological questions regarding community activity, recruitment, and succession in this environment remain ... -
Microbial inventory of deeply buried oceanic crust from a young ridge flank
Jørgensen, Steffen Leth; Zhao, Rui (Peer reviewed; Journal article, 2016-05-27)The deep marine biosphere has over the past decades been exposed as an immense habitat for microorganisms with wide-reaching implications for our understanding of life on Earth. Recent advances in knowledge concerning this ... -

Nitrifier abundance and diversity peak at deep redox transition zones
Zhao, Rui; Hannisdal, Bjarte; Mogollon, Josè M.; Jørgensen, Steffen Leth (Peer reviewed; Journal article, 2019-06-14)More than half of the global ocean floor is draped by nutrient-starved sediments characterized by deep oxygen penetration and a prevalence of oxidized nitrogen. Despite low energy availability, this habitat hosts a vast ...
