Monopotassium phosphite

CAS: 13977-65-6

Monopotassium phosphite is a toxic substance with a strong inhibitory effect on bacteria, microorganisms and autotrophs. Monopotassium phosphite is structurally similar to hypophosphite, whereas monopotassium phosphite has an additional potassium ion. It can be found in high concentrations in the cells of microalgae such as Botryococcus braunii. Monopotassium phosphite inhibits the growth of bacteria by inhibiting the transfer of phosphorus from ATP to other compounds and by altering the structure of bacterial cell membranes. Monopotassium phosphite also inhibits the growth of fungi, algae and plants that require phosphate for their metabolic processes (i.e., photosynthesis).
