Biocontrol of green mold decay of citrus has been studied extensively in the past,
and unlike some strains of bacteria, P. polymyxa is not normally regarded as the human pathogen
Compared with yeast, bacterial biocontrol agents survive in the microenvironments needed to prevent disease and quickly become non-detectable on the surface of the fruit.
This may be advantageous for consumers who are concerned with pesticide residues .
These properties together with endospore forming potential enables P. polymyxa strain SG-6 to resist a wide range of environmental stresses.
