Figure 1From: Biodiversity of poly-extremophilic Bacteria: Does combining the extremes of high salt, alkaline pH and elevated temperature approach a physico-chemical boundary for life? Correlation of [Na + ] optimum and pH or temperature optima of extreme halophiles. Figure 1a. Correlation between [Na+] optimum and pH optimum. [Na+] optimum (M) is plotted against pH optimum; number of microorganisms at each locus is plotted on z-axis as indicated by color coding; no representation (zero) is indicated in the darkest shade.Figure 1b. Correlation between [Na+] vs. temperature optima. [Na+] optimum (M) is plotted against temperature optimum (°C); number of microorganisms at each locus is plotted on z-axis as indicated by color coding; no representation (zero) is indicated in the darkest shade.Back to article page
