A study published in PLOSone back in September analyzed the microbial-fighting capability of … well, microbes. The authors evaluated the efficacy of cleaning hospital rooms with food-grade Bacillus subtilis, Bacillus pumilus, and Bacillus megaterium. The authors concluded that cleaning hospitals rooms with these organisms reduced the number of hospital-acquired-infection-causing organisms on surfaces.
It’s an intriguing idea, and not that out of the box; lots of antimicrobial agents are derived from other microorganisms (I’m looking at you, penicillin). It’ll be interesting to see where other researchers take this.
