Bacterial isolates were collected directly from the water column or in F/2 enrichments to induce diatom blooms. Particles were individually picked, rinsed with 0.22-μm-pore-size filtered seawater, and plated on ZoBell 2216E plates to isolate attached bacteria. Free-living bacteria were isolated from seawater filtrate (pore size, 1.0 μm) on ZoBell 2216E plates. Organisms whose designations are not listed were isolated from seawater with no visible particles.
