From: Surfactant-associated bacteria in the near-surface layer of the ocean

Relative abundance of surfactant-associated genera observed during the experiment shown in Fig. 3.
Genus-level taxonomic assignments of 16S rRNA gene were used to determine relative abundance of the potential surfactant producers and decomposers and non-producer/decomposers in each location (SML and SSW stand for sea surface microlayer and subsurface water, respectively).
