A purple nonsulfur photosynthetic bacteria, Rhodobacter sphaeroides, through the Calvin reductive pentose phosphate pathway by ribulose 1,5-bisphosphate carboxylase/oxygenase, can produce organic compounds such as sugar, amino acid, nucleic acid, vitamin and bio-active substances from carbon dioxide. Therefore, this study is focused on the production of amino acids under different light conditions in Rhodobacter sphaeroids wild type and mutant type (MBTLJ-8), and the impact on physiological activation of other microorganisms by various compositions of organic compounds produced from R. sapheroids wild type and MBTLJ-8. In this result, the high content of various amino acids in mixed organic compounds could be obtained from the MBTLJ-8 mutant strain, comparing to wild type, In addition, the addition of the mixed organic compounds into culture media of Escherichia coli BL21 gave the effect on the enhancement of growth rate of E. coli. Therefore, MBTLJ-8 provides the strong evidence that photosynthetic production of mixed organic compounds have the functional potential to increase the physiological activity of other organisms. |
