The April 2020 Journal of the Federation of American Societies for Experimental Biology contains study results from researchers at New Jersey City University on the use of hempseed oil extract as an anti-biofilm agent, key to the inhibition of dangerous pathogenic microbes:
Biofilm formation is an important virulence factor and a crucial step in the pathogenesis of bacterial infection for certain microorganisms. Bacteria attaching to surfaces and forming biofilms are resistant to antibiotic treatment and antimicrobial agents, which makes them difficult to eradicate. Worldwide, an increasing number of pathogenic bacteria and yeast have been gaining antibiotic and anti‐fungal resistance. This is a critical problem for public health as millions of people acquire infections from pathogenic antibiotic resistant microorganisms such as Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa, and Candida albicans. For many years now, scientists have been looking for natural alternatives like herbs, oils, and seed extracts to control the rise of antibiotic resistant microbial infections and support better health. Chia, Flax, and Hemp seed oil extracts have been found to support skin health and improve immunity and cardiovascular function. However, very little is known about their effects on the growth of pathogenic microorganisms. The purpose of this study is to test these oil‐seed‐extracts for anti‐biofilm properties. Using the biofilm assay we were able to show that Chia seed oil extract and Hemp seed oil extract had the most effective anti‐biofilm properties against P. aeruginosa and S. epidermidis. Preliminary chemical characterization of these oils was initiated to determine the active fraction displaying anti‐biofilm properties. Additional testing will be done to further characterize the active compound in each of these oils.
