Incapability of Gluconobacter oxydans to produce tartaric acid.

The dependence of tartaric acid production by Gluconobacter oxydans ssp. oxydans ATCC 19357 and G. oxydans ssp. suboxydans ATCC 621 on vanadate was investigated. It was found with both organisms that tartaric acid could only be produced in a medium containing vanadate (NH(4)VO(3)). A proposed intermediate of the tartaric acid metabolism in G. oxydans, 5… (More)
