A new perspective on microbes formerly known as nitrite-oxidizing bacteria

H Daims, S Lücker, M Wagner - Trends in microbiology, 2016 - cell.com
Nitrite-oxidizing bacteria (NOB) catalyze the second step of nitrification, nitrite oxidation to
nitrate, which is an important process of the biogeochemical nitrogen cycle. NOB were …

Global observing needs in the deep ocean

LA Levin, BJ Bett, AR Gates, P Heimbach… - Frontiers in Marine …, 2019 - frontiersin.org
