Abstract/OtherAbstract:
Ketogulonicigenium vulgare DSM 4025, known as a 2-keto-L-gulonic acid producing strain from L-sorbose via L-sorbosone, surprisingly produced L-ascorbic acid from D-sorbitol, L-sorbose, L-gulose, and L-sorbosone as the substrate under a growing or resting condition. As the best result, K. vulgare DSM 4025 produced 1.37 g per liter of L-AA from 5.00 g per liter of L-sorbosone during 4 h incubation time at 30 degrees C under the resting cell condition having 5.70 g per liter of wet cells. The precursor of L-AA formation from D-sorbitol and L-sorbose, except for L-gulose, was thought to be the putative furanose form of L-sorbosone. This is the first time it is reported that bacteria can produce vitamin C via L-sorbosone.
