example 1

[0138]In this example, oxyhydrogen microorganisms that accumulate high lipid content and / or other valuable compounds such as polyhydroxybutyrate (PHB) to are grown on an inorganic medium with CO2 as the carbon source and hydrogen acting as the electron donor while oxygen provides the electron acceptor. Oxyhydrogen microbes such as these can be used in certain embodiments of the present invention in converting C1 chemicals such as carbon dioxide into longer chain organic chemicals.

[0139]Static anaerobic reaction vessels were inoculated with Cupriavidus necator DSM 531 (which can accumulate a high percentage of cell mass as PHB). The inoculum were taken from DSM medium no. 1 agar plates kept under aerobic conditions at 28 degrees Celsius. Each anaerobic reaction vessel had 10 ml of liquid medium DSM no. 81 with 80% H2, 10% CO2 and 10% O2 in the headspace. The cultures were incubated at 28 degrees Celsius. The Cupriavidus necator reached an optical density (OD) at 600 nm of 0.98 and a ...

Abstract

Compositions and methods for a hybrid biological and chemical process that captures and converts carbon dioxide and/or other forms of inorganic carbon and/or CI carbon sources including but not limited to carbon monoxide, methane, methanol, formate, or formic acid, and/or mixtures containing CI chemicals including but not limited to various syngas compositions, into organic chemicals including bio-fuels or other valuable biomass, chemical, industrial, or pharmaceutical products are provided. The present invention, in certain embodiments, fixes inorganic carbon or CI carbon sources into longer carbon chain organic chemicals by utilizing microorganisms capable of performing the oxyhydrogen reaction and the autotrophic fixation of CO2 in one or more steps of the process.
