Abstract

Facultative CO2 and N2 fixing bacteria are a special class of microorganisms that can simultaneously fix CO2 and N2 from the atmosphere and use it as a carbon source and nitrogen source, respectively. Discovery of useful metabolites from these microbes would be analogous to turning waste into wealth, as it would not only reduce production costs, but also provide an environmentally safe alternative to inorganic fertilizers. In this study, some common metabolites, including extracellular polysaccharides, extracellular proteins, lipids, alcohols, ketones, and esters were detected from thirty three facultative CO2 and N2 fixing bacteria using preliminary methods, such as the phenol - acid method, Coomassie brilliant blue method, method of loss of weight, and gas phase chromatography. The results showed that there are 4 types of facultative fixed CO2, N2 bacteria that can produce extracellular polysaccharides, 6 types that can produce extracellular protein, 4 types that can produce lipids, 2 types that can produce ethanol, 1 type that can produce acetone, and 2 types that can produce esters. This information will provide a theoretical basis for future research and applications.
