This spectrum shows two different
kinds of proteorhodopsin proteins
identified in the study.
One proteorhodopsin absorbs in
the green range of light;
the other absorbs in the
blue range of
light.

Ribosomal RNA probes developed by DeLong's
research lab are used
to identify the SAR86 bacterial group in
seawater samples
(SAR86 bacteria glow red with the rRNA
probe).

Special bottles mounted on a CTD rosette can be
deployed from a ship to collect seawater samples from which oceanic
bacteria can be extracted.
