Abstract:
Provided herein are methods and compositions useful for detecting the production of compounds in a cell, for example, a microbial cell genetically modified to produce one or more such compounds at greater yield and/or with increased persistence compared to a parent microbial cell that is not genetically modified. In some embodiments, the methods comprise contacting a solution with a fluorescent dye that directly binds the recombinantly produced compound, wherein the solution comprises a plurality of cells recombinantly producing the compound; and detecting the fluorescent dye under spectral conditions suitable for the selective detection of the fluorescent dye bound to the recombinantly produced compound.
Abstract:

Abstract:
The present invention relates to a transformed eukaryotic cell comprising one or more nucleotide sequence(s) encoding acetyl-CoA acetyltransferase, 3-hydroxybutyryl-CoA dehydrogenase, 3-hydroxybutyryl-CoA dehydratase, butyryl-CoA dehydrogenase, alcohol dehydrogenase or acetaldehyde dehydrogenase and/or NAD(P)H-dependent butanol dehydrogenase, whereby the nucleotide sequence(s) upon transformation of the cell confer(s) the cell the ability to produce butanol. The invention also relates to a process for the production of butanol.
Abstract:
The present invention relates to recombinant host cells polynucleotides and polypeptides, methods for their production, and methods for their use in production of hydrocarbons. Disclosed herein are methods, compositions and hosts for synthesizing hydrocarbons and derivatives thereof. In one non-limiting embodiment, the methods, compositions and hosts are used to synthesize hydrocarbons comprising one or more isoprene units as depicted in Formula I as well as salts or derivatives thereof. An aspect of the present invention relates to a genetically engineered host capable of producing hydrocarbons or derivatives thereof via a mevalonate (MVA) pathway.
Abstract:
The present disclosure provides recombinant bacteria with elevated production of ethanol and/or n-butanol from ethylene. Methods for the production of the recombinant bacteria, as well as for use thereof for production of ethanol and/or n-butanol are also provided.
Abstract:
This disclosure describes enzymes from the type II (a discrete set of enzymes) fatty acid synthesis ("FAS") pathway that can be used in combination with thiolases to operate a functional reversal of the β-oxidation cycle. A combination of thiolases with one or more of 3-oxoacyl-[acyl-carrier-protein] reductase (FabG, others), 3-hydroxyacyl-[acp] dehydratase (FabA, FabZ, others), and enoyl-[acyl-carrier-protein] reductase (FabI, FabK, FabL, FabV, others) yields a functional reversal of the β-oxidation cycle. If only one or two enzymes are used, the remaining enzymes will be traditional beta oxidation enzymes. Once this cycle is coupled with the appropriate priming and termination pathways, the production of carboxylic acids, alcohols, hydrocarbons, amines and their α-, β-, and ω-functionalized derivatives from renewable carbon sources can be achieved.
