Background: Succinic acid can be used as a precursor of many industrially important chemicals and has an extensive application range to apply in different industrial areas, such as pharmaceutical and food industry. Objective: In this work, we isolated a strain of B. megaterium which produces succinic acid in optimized czapek medium for its production. Methods: A study of the production of this organic acid was realized in different media adding insoluble phosphate sources to czapek medium. Results: Two Bacillus strains ELI 24 and ELI30 that were isolated from soil in Mexico were fully characterized as Bacillus megaterium and B. thuringiensis. B. megaterium ELI 24 was proved to secrete succinic acid which was clearly identified by spectroscopic methods, such as 1H and 13C NMR, and X-ray analysis. Conclusion: This organic acid could improve the solubility of insoluble phosphate, which could help in the growth of plants.

ABSTRACT Comparative analysis of the genomes of mixed-acid-fermenting Escherichia coli and succinic acid-overproducing Mannheimia succiniciproducens was carried out to identify candidate genes to be manipulated for overproducing succinic acid in E. coli. This resulted in the identification of five genes or operons, including ptsG, pykF, sdhA, mqo, and aceBA, which may drive metabolic fluxes away from succinic acid formation in the central metabolic pathway of E. coli. However, combinatorial disruption of these rationally selected genes did not allow enhanced succinic acid production in E. coli. Therefore, in silico metabolic analysis based on linear programming was carried out to evaluate the correlation between the maximum biomass and succinic acid production for various combinatorial knockout strains. This in silico analysis predicted that disrupting the genes for three pyruvate forming enzymes, ptsG, pykF, and pykA, allows enhanced succinic acid production. Indeed, this triple mutation increased the succinic acid production by more than sevenfold and the ratio of succinic acid to fermentation products by ninefold. It could be concluded that reducing the metabolic flux to pyruvate is crucial to achieve efficient succinic acid production in E. coli. These results suggest that the comparative genome analysis combined with in silico metabolic analysis can be an efficient way of developing strategies for strain improvement.
