Image:Flickr/Ashley TaylorI don't know about you, but after accidentally farting in a stranger's face during a math lecture (don't ask), I dream of a future where fart-neutralizing pants are readily available. But before we can design these desperately needed products, we must first develop realistic artificial farts with which to test them. That's where these Danish scientists come in. They used common lab strains of different species of bacteria to develop a "recipe" that yields a realistic fart odor when grown anaerobically. Artificial fart scientists, we salute you!Design of artificial foetor flatus based on bacterial volatile compounds. "INTRODUCTION: Excessive flatulence can be a huge social problem. The purpose of this study was to design artificial flatus from bacterial volatile compounds to stimulate research into neutralizing measures. MATERIAL AND METHODS: Anaerobic bacteria, representing a broad spectrum, from a recognized international culture collection were included. The strains were incubated in an anaerobic jar. After 24 hours the lid was removed, and the odour was evaluated by a specialist in clinical microbiology. RESULTS: Four different anaerobic strains were chosen for further studies based on their individual odours. In total, seven different combinations of two or three strains were tested. The combination of Bacteroides fragilis ATCC 25285, Clostridium difficile ATCC 700057 and Fusobacterium necrophorum ATCC 25286 was chosen as it had a suitably foul odour. CONCLUSION: It is possible to design artificial flatus from bacterial volatile compounds. The method is easy and inexpensive and can stimulate further research into neutralizing measures."
