The Growth-Favoring Range

No microbe grows at every heat or every acidity. Each one has a lowest point, a best point and a highest point. Move both sliders. The top chart shows who the heat favors. The lower chart shows who the acid favors. The last panel puts the two together for a common pathogen.

Most microbes that make people ill are mesophiles and neutrophiles. This meter multiplies the two scores for one of them, an Escherichia coli type cell. Heat alone is not enough. The acid has to suit it too.
