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: The present invention relates to novel nucleic acid sequences encoding bacterial xylose isomerases that upon transformation of a eukaryotic microbial host cell, such as yeast, to confer to the host cell the ability of isomerising xylose to xylulose. The nucleic acid sequences encode xylose isomerases that originate from bacteria such as Eubacterium sp., Clostridium cellulosi and others. The invention further relates to fermentation processes wherein the transformed host cells ferment a xylose-containing medium to produce ethanol or other fermentation products.

摘要: Provided herein is a genetically engineered microbe which accumulates citramalate. In one embodiment, the microbe includes an exogenous polynucleotide encoding a citramalate synthase which catalyzes the condensation of acetyl CoA and pyruvic acid. Optionally, the microbe also includes a second exogenous polynucleotide encoding a citrate synthase which catalyzes the condensation of acetyl CoA and oxaloacetate, and the citrate synthase activity in the microbe is reduced compared to a control microbe. In one embodiment, the citrate synthase includes at least one amino acid substitution in the acetyl-CoA binding pocket, the mobile loop, the NADH binding site, and the oxaloacetate binding site, or a combination thereof. Also provided herein are methods for using the genetically engineered microbe, including a method for producing citramalate. The method can further include isolating the citramalate.

摘要: A method of preserving a biomass. The method comprises adding an acid solution to a biomass comprising microalgae to form an acidified microalgae biomass composition. The acidified microalgae biomass composition is stored under anaerobic conditions without inoculating the acidified microalgae biomass composition with bacteria. An additional method of preserving a biomass comprises storing the acidified microalgae biomass composition under anaerobic conditions and exposing the acidified microalgae biomass composition to carbon dioxide, nitrogen, or a combination thereof to produce a coproduct comprising succinic acid. Yet another method of preserving a biomass comprises storing the acidified microalgae biomass composition under anaerobic conditions and in the presence of carbon dioxide. A preserved biomass is also disclosed.
