AbstractOxygen deficient zones (ODZs) are subsurface marine systems that harbor distinct microbial communities, including populations of the picocyanobacteria Prochlorococcus that can form a secondary chlorophyll maximum (SCM), and low-oxygen tolerant strains of the globally abundant heterotroph Pelagibacter (SAR11). Yet, the small labile molecules (metabolites) responsible for maintaining these ODZ communities are unknown.

INTRODUCTION Picocyanobacteria contribute greatly to primary production, especially in oligotrophic regions (Rii et al., 2016). Prochlorococcus and Synechococcus are abundant under different ocean regimes, with Prochlorococcus dominating in the oligotrophic ocean nominally from 40° N to 40° S, and Synechococcus extending to both cold and high nutrient regimes (Flombaum et al., 2013).
