Figure 6. MDH activity in strain ΔmxaF grown on the methanol and succinate media with Ca²⁺ and/or La³⁺.

Cells were grown aerobically in succinate (white bar) and methanol (gray bar) media with 30 µM Ca³⁺, La³⁺, and Ca²⁺+La³⁺ at 30°C. n.d.: not detected, and n.g.: no growth. Results are shown as means with standard deviations (n = 3).
