Paenibacillus polymyxa is a Gram-positive bacterium capable of fixing nitrogen. The species may also be known as Bacillus polymyxa. It is found in soil, plant roots, and marine sediments. Strains of this species were also isolated from cod intestines by students at the University of Tromsø in February 2009. Some strains of P. polymyxa produce polymyxin antibiotic compounds. Surfactant complexes isolated from P. polymyxa have been shown to be effective in disrupting biofilms of Bacillus subtilis, Micrococcus luteus, Pseudomonas aeruginosa, Staphylococcus aureus and Streptococcus bovis.
|COGEM released a comprehensive database of pathogenicity assessment of around 2575 bacterial species in 2011. The database ranks the pathogenicity of species on a scale of 1 to 4. Paenibacillus polymyxa ranks 1 on this scale: The species or strain does not belong to a recognized group of
disease-invoking agents in humans or animals and/or has an extended history of safe usage under conditions
