 "Stenotrophomonas" species range from common soil organisms ("S. nitritireducens") to opportunistic human pathogens ("S. maltophilia"), the molecular taxonomy of the genus is still somewhat unclear.The most common species, "S. maltophilia" is very versatile and can be beneficial for plant growth and health, can be used in agriculture, biocontrol, bioremediation and phytoremediation strategies as well as the production of biomolecules of economic value.On the other hand, some of "S. maltophilia" strains are pathogenic to humans with multidrug resistant profile.
