Sterilization

Study finds Bunsen burners fail to sterilize lab workspaces, may worsen contamination

A study published in Microbiology Spectrum tested the long-held belief that Bunsen burners create protective convection currents that clear bacteria from lab benches. Researchers led by microbiologist Hannah Gavin used a visible strain of bacteria, Gordonia rubripertincta, to show the burners did not reduce contamination and in some cases spread it further across surfaces.
