Sea Yeast

Sea Yeast is a kind of single cellular organism that exists in the seas of the world, mostly common on the Calm Belts.

Fermentation
Sea Yeast are able to fermentate generally everything around them in the water into differing compounds, but namely Sea Yeast are able to produce a compound with characteristics similar to kairoseki. It is able to negate devil fruit only on great quantities but in general is simply very good at disguising them from marine predators. Their common name of Sea Yeast plays from this ability despite not being really stereotypical yeast, as their preferred method of obtaining sustenance is by respiration.

Respiration
Sea Yeast are nothing short of the super-sayan version of mitochondria. Sea Yeast is able to produce energy several degrees higher from oxygen and aerobic respiration in general then any normal cell can on every circumstance. This ability of Sea Yeast is barely understood because science in general isn't advanced enough to understand the full process.

Effects on the human body
Consumption of Sea Yeast is in general beneficial, Sea Yeast however will not be digested by the body and will naturally be assembled into the metabolism, namely into places they can supply the body with energy.

Sea Yeast and human cells in general work in a symbiotic relationship, in trade for shelter and a steady supply of food and oxygen the Sea Yeast supplies the body with massive amounts of energy. This symbiotic relationship is the basis of Jibuki's superhuman benefits, and is the largest and most important component of the training regime.

Furthermore as the by product of Sea YEast fermentation becomes trapped within the body those who have consumed Sea Yeast are inherently unable to utilize a devil fruit, but instead are able to negate the effects of them with touch alone.
