英文摘要: Abstract(#br) Background(#br)In the industry, the conventional two-step fermentation method was used to produce 2-keto- l -gulonic acid (2-KGA), the precursor of vitamin C, by three strains, namely, Gluconobacter oxydans , Bacillus spp. and Ketogulonicigenium vulgare . Despite its high production efficiency, the long incubation period and an additional second sterilization process inhibit the further development. Therefore, we aimed to reorganize a synthetic consortium of G. oxydans and K. vulgare for one-step fermentation of 2-KGA and enhance the symbiotic interaction between microorganisms to perform better.(#br) Results(#br)During the fermentation, competition for sorbose of G. oxydans arose when co-cultured with K. vulgare . In this study, the competition between the two microbes was...
