摘要： An engineered microorganism(s) with novel pathways for the conversion of short-chain hydrocarbons to fuels and chemicals (e.g. carboxylic acids, alcohols, hydrocarbons, and their alpha-, beta-, and omega-functionalized derivatives) is described. Key to this approach is the use of hydrocarbon activation enzymes able to overcome the high stability and low reactivity of hydrocarbon compounds through the cleavage of an inert C—H bond. Oxygen-dependent or oxygen-independent activation enzymes can be exploited for this purpose, which when combined with appropriate pathways for the conversion of activated hydrocarbons to key metabolic intermediates, enables the generation of product precursors that can subsequently be converted to desired compounds through established pathways. These novel engineered microorganism(s) provide a route for the production of fuels and chemicals from short chain hydrocarbons such as methane, ethane, propane, butane, and pentane.

摘要： An engineered microbe that contains a designed platform for the conversion of one-carbon substrates to chemical products is described. The designed platform embodies a new metabolic architecture that consolidates carbon fixation, central metabolism, and product synthesis into a single pathway. This is made possible by the key finding that 2-hydroxyacyl-CoA lyase, an enzyme in the α-oxidation pathway, is capable of catalyzing the C—C bond formation between formyl-CoA and aldehydes of different chain lengths, allowing for the elongation of the carbon backbone of said aldehyde by one-carbon units. These novel microbes present an opportunity for the production of chemicals from single-carbon feedstocks such as carbon dioxide, carbon monoxide, formate, formaldehyde, methanol or methane.

摘要： The invention relates to the development of appropriate cultivation conditions for a bacteria to grow anaerobically (fermentatively) on a glycerol substrate. The method requires culturing bacteria having a functional 1,2-propanediol pathway and a functional type II glycerol dehydrogenase-dihydroxyacetone kinase pathway in a culture medium containing high concentrations of glycerol, a neutral to mildly acidic pH, low levels of potassium and phosphate, and high levels of CO2, such that glycerol is thus converted into a desirable product, such as ethanol, —hydrogen, formate, succinate, or 1,2-propanediol.

摘要： The production of substituted 2-hydroxyacyl-CoA molecules by a novel reaction is described. The reaction involves the condensation of formyl-CoA with a carbonyl-containing molecule. Such carbonyl-containing molecules include a substituted aldehyde and a ketone. The reaction is catalyzed by enzymes using a TPP-dependent mechanism. Also described is the production of unsubstituted and substituted 2-hydroxyacyl-CoA molecules comprising the condensation of formyl-CoA with a carbonyl-containing molecule, wherein the condensation is catalyzed by a prokaryotic HACL. The 2-hydroxyacyl-CoA can be converted to chemical products having broad applications by using enzyme catalysts. The combination of enzyme catalysts comprises novel biochemical reaction pathways that can be deployed either as polypeptides in a reaction buffer or genetically encoded in recombinant microorganisms.
