Figure 4. Cross diagram of the temperature-pressure dependence of P. phosphoreum ANT-2200.

(A) Extrapolated-contour diagram of the temperature-pressure dependence for both the growth rate (r, h⁻¹) and the maximum population density (K, OD_{600 nm}) for P. phosphoreum ANT-2200. The cross coefficient C_r–K is defined as: 0<C_r–K<1. (B) Standard deviation associated to the C_r–K coefficient. The grey circles indicate parameter values used to extrapolate the contours. Size is proportional to their values. The black circle corresponds to the in situ conditions for the strain. Isolines define zones with same level of values.
