In Purple nonsulfur photosynthetic bacteria, carbon dioxide fixation has been intensively investigated, and through the Calvin reductive pentose phosphate pathway by ribulose 1,5-bisphosphate carboxylase/ oxygenase, this organism can produce organic compounds such as sugar from carbon dioxide. However, very little is known about the physicochemical properties and functional potentials of organic compounds produced from carbon dioxide by photosynthetic bacteria. Therefore, this study is focused on analyzing the properties of organic compounds and the impact on physiological activation of other microorganisms by carbon dioxide fixed organic compounds. The organic compounds was hydrolyzed by a mixture of cellulose and b-glucosidase because of its structural complexity, and after supplementation of mixed hydrolytic enzymes, we could get the increased yields of glucose, galactose and arabinose. In addition, the impact of organic compounds produced by carbon dioxide fixation was assessed by the growth rate and fermentation efficiency of Saccharomyces cerevisiae and Clostridium acetobutylicum. We found that physiological activation of two microorganisms was induced under the supplemented condition by organic compounds. The data provide strong evidence that carbon dioxide fixed organic compounds have the multifunctional potential to substantially increase the physiological activity of other organisms.
