Figure 1. Growth of the wild-type strain AM1 on methanol or succinate media supplemented with Ca²⁺ or/and La³⁺.

The growth of strain AM1 on methanol or succinate media supplemented with Ca²⁺ (black circle), with La³⁺ (gray circle), with Ca²⁺+La³⁺ (white circle) and without Ca²⁺ and La³⁺ (white square). The concentration of Ca²⁺ and La³⁺ in the medium are 30 µM each. Points on the graphs depict average data from three biological replicates.
