Abstract: As well as from Paraguayan soil samples of a stevia plantation as from samples
of Belgian soils that never had contact with stevia or steviol glycosides bacterial
consortia were derived that hydrolysed steviol glycosides to steviol. This activity
was not influenced by heating (20 min. 80 °C) or boiling (10 min. 100 °C) the
soil samples. The type of steviol glycosides that were hydrolysed as well as the
hydrolytic pathway of the hydrolysis was highly influenced by the conditions of
the incubation. Prolonged incubation with one of the consortia yielded a two new
compounds designated as Monicanone en dihydromonicanone. Full chemical
characterization showed that this compounds were formed from steviol by removing
the A-ring.
