Heterotrophic (non-pigmented) bacteria abundances determined by flow cytometry (post-cruise/on-shore analysis) from samples collected on R/V Melville cruise MV1008 in the Costa Rica Dome in 2010 (CRD FLUZiE project)

Abstract

Non-pigmented bacteria abundances from preserved (0.5% paraformaldehyde) frozen samples run on a Beckman-Coulter Altra flow cytometer after staining with Hoechst 33342 DNA stain and excitation with 200 mW UV and 1W 488 nm laser light. Bacteria discriminated based on DNA content (450±40 nm), as well as forward and 90° side light scatter parameters. Samples were collected on the MV1008 cruise in the Costa Rica Dome (CRD) region of the Eastern Tropical Pacific Ocean.
