As much as 60% of the nitrogen found in "Mimosa pudica" can be attributed to the fixation of N2 by bacteria. "Burkholderia" "phymatum" STM815T and "Cupriavidus" "taiwanensis" LMG19424T are beta-rhizobial strains of diazotrophs that are highly effective at fixing nitrogen when coupled with "M. pudica". "Burkholderia" is also shown to be a strong symbiont of "Mimosa pudica" in nitrogen-poor soils in regions like Cerrado and Caatinga.
