Fig. 4: Flow-cytometric characterization of microorganisms from BLM1.
From: Evolutionary stasis of a deep subsurface microbial lineage

A Oxidoreductase activity and (B) nucleic acid content analyzed by flow cytometry at BLM1 site in California. Identified cells are color-coded, with CDA colored red and enlarged for visual recognition. The Y-axis is fluorescence. The X-axis is estimated diameter of the sorted cells, derived from the forward light scatter.
