Bacteria Probiotic Deodorants

Is there anyone you know of currently working on a probiotic deodorant? I know of some probiotic deodorants that use shelf-stable probiotics designed for the gut (mostly lactobacillus and bifidobacterium strains). This might have a temporary effect but I know that the long-term survival of gut bacteria on the skin is very unlikely. I was was thinking of making my own probiotic deodorant with prebiotic starches, and a super broad-spectrum probiotic (General Biotic's Equilibrium) mixed with an oral probiotic (Evora Plus) in hopes that one of the 118 strains will hold, but it seems unlikely given how different those ecosystems are. If you don't know of any commercially available or r&d-stage probiotic deodorants, could you tell me which of commercially available shelf-stable probiotic strains that are more likely to survive in the underarm environment?
