Description
Ben Niu, Yiming Sun, Yongwu Niu, and Shan Qiao wrote this research paper, published in 2024. It pairs ultrasound with rhamnolipids, a soap made by bacteria, to strip Bacillus cereus biofilms off surfaces far better than either treatment manages alone.
This spore-forming bacterium's biofilms are a stubborn cause of food contamination and lost product. The biosurfactant alone removed about sixty-three percent of biofilm at its best dose. A low dose plus twenty minutes of ultrasound matched that. The strongest pairing, full dose and a full hour of sound, cleared nearly seventy-nine percent. Microscope images showed torn biofilm, deformed cells, and the slime matrix gone. The combination also suppressed the cells' metabolism, clumping, and surface grip, and starved new biofilm of its sugars and proteins. Ultrasound worked by opening the film so the soap could penetrate.
