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.
