Abstract
In industrial production, the precursor of
l
-ascorbic acid (L-AA, also referred to as vitamin C), 2-keto-
l
-gulonic acid (2-KLG), is mainly produced using a classic two-step fermentation process performed by
Gluconobacter oxydans
,
Bacillus megaterium
, and
Ketogulonicigenium vulgare
. In the second step of the two-step fermentation process, the microbial consortium of
K. vulgare
and
B. megaterium
is used to achieve 2-KLG production.
K. vulgare
can transform
l
-sorbose to 2-KLG, but the yield of 2-KLG is much lower in the monoculture than in the coculture fermentation system.
