Abstract: The growth and interaction of Gluconobacter oxydans and Bacillus megaterium in Vc two step fermentation have been studied.The results showed that there is a kind of coordinate symbiosis between G. oxydans and B. megaterium during the fermentation,which could promoted 2-Keto-L-gulonic acid (2KGA) symthesis. The efficiency on the synbiosis would vary as the conditions of fermentation were different and were improved by the environmental factors.
