Table 2. Bacteria predominant in small and large N. salina cultivation systems.

A) Ten most abundant bacterial orders identified in small growth systems. B) Ten most abundant bacterial orders identified in large growth systems. Zero values represent relative abundances less than 0.05%. Ph, Phylum (for phylum abbreviations, see Table 1). Heat maps are formatted separately for each growth system as in Table 1. Σ, total abundance of these ten orders in each system. Σ_{(Saprospirales + Cytophagales)}, combined abundance of the orders Saprospirales and Cytophagales in each system. Σ_{(Cytophagales + Flavobacteriales)}, combined abundance of the orders Cytophagales and Flavobacteriales in each system.
