History

In 2001 while on a date near some horse stables, engineer David Whitlock was asked why horses roll in the dirt. Not knowing the answer, he studied soil samples and hypothesized that the ''

Nitrosomonas eutropha ''Nitrosomonas eutropha'' is an ammonia-oxidizing, Gram-negative bacterium from the genus of ''Nitrosomonas''. Starting in 2014, it was being tested by the biotech company AOBiome AOBiome is a Boston-based biotech company focused on transf ...

'' that he found present was a key species as these bacteria feed on ammonia and thus could provide a symbiotic ammonia processing function for horses and other vertebrates. To test this theory he suspended the bacteria in water and coated himself with them and then stopped bathing in order to give the AOB a chance to colonize his body. Whitlock has reported in national media that he has not had a shower in over 10 years, but washes his hands before eating, with a number of journalists confirming that he does not smell bad as a result. Whitlock has speculated, along the lines of the “

AOBiome's cosmetic partner Mother Dirt is therefore the first skincare company to formulate products that support the growth of healthy bacteria.

Clinical trials

AOBiome is developing topical biologics for the treatment of inflammatory conditions, specifically looking at the therapeutic properties of ammonia-oxidizing bacteria. AOBiome started its Phase 2 clinical trial for adult acne in 2015. AOBiome has received attention for its prospective interventional study on the link between a bacteria-infused topical spray and
