Phosphate availability modulates the weathering effectiveness and molecular response of Caballeronia mineralivorans PML1(12).

ABSTRACT:

Backgrounds

Minerals and rocks are important reservoirs of nutrients for the soil biota because of their nutritive contents of P, K or Mg. In nutrient-poor environments such as forest soils, microorganisms capable of mobilizing these nutrients gain an ecological advantage. Acidification-based mineral weathering is one of the mechanisms used by these bacteria, but the molecular players involved and their regulation remain poorly characterized.

Methods

To fill these gaps, we considered the effective mineral weathering bacterial strain Caballeronia mineralivorans PML1(12). On the basis of the hypothesis that nutrient availability conditions the effectiveness of bacterial mineral weathering, we considered the impact of different nutrients (i.e., Mg, K and P) typically contained
