The present invention relates to a new strain of Clostridium acetobutylicum modified to be unable to produce hydrogen and its use for the continuous production of bulk chemicals such as lactate, 1,3-propanediol, ethanol, butanol, isobutanol, 1,3-butanediol, acetate, acetone, isopropanol, 3-hydroxy-3-methylbutyrate and isobutene at high yield.

Disclosed is a mutant strain having the ability to produce polyhydroxybutyrate. The novel strain has a significantly high growth rate and an improved ability to produce PHB compared to existing PHB-producing cyanobacterial strains. Therefore, the novel strain is suitable for use in the production of PHB and the development of various products using PHB. In addition, the novel strain is useful as a photosynthetic strain for developing a PHB production process using industrial flue gas due to its ability to produce PHB from only CO.sub.2 without any additional organic carbon source. Also disclosed is a method for producing polyhydroxybutyrate using the mutant strain.

This document relates to using bidirectional, multi-enzymatic scaffolds to biosynthesize cannabinoids in recombinant hosts.

Methods of using microorganisms to make chemicals and fuels, including carboxylic acids, alcohols, hydrocarbons, and their alpha-, beta-, and omega-functionalized derivatives are described. Native or engineered thiolases are used condense a growing acyl-ACP and acetyl-ACP in combination with type II fatty acid synthesis. The resulting fatty acid biosynthesis cycle has an ATP yield analogous to the functional reverse β-oxidation cycle.

Provided is a method of producing at least one omega-hydroxyl fatty acid, the method comprising: (a) contacting at least one alkane with at least one recombinant yeast cell in an aqueous medium, wherein the yeast cell is capable of oxidising the alkane to the corresponding omega-hydroxyl fatty acid and the yeast cell comprises a reduced fatty acid degradation capacity.

Described are a genetically modified microorganism and corresponding methods and products. The genetically modified microorganism may include a first gene that encodes an acyl transferase and a second gene that encodes a peptide or protein. One or both of the first and second gene may be heterologous. The genetically modified microorganism may include a modified acyl-CoA biosynthetic pathway configured for one or more of: inducible biosynthesis of an acyl-CoA and over-accumulation of the acyl-CoA. The genetically modified microorganism may be effective upon fermentation to cause acylation of the peptide or protein by the acyl transferase using the acyl-CoA to provide a N-acylated peptide or protein product.

The invention provides non-naturally occurring microbial organisms containing a fatty alcohol, fatty aldehyde or fatty acid pathway, wherein the microbial organisms selectively produce a fatty alcohol, fatty aldehyde or fatty acid of a specified length. Also provided are non-naturally occurring microbial organisms having a fatty alcohol, fatty aldehyde or fatty acid pathway, wherein the microbial organisms further include an acetyl-CoA pathway. In some aspects, the microbial organisms of the invention have select gene disruptions or enzyme attenuations that increase production of fatty alcohols, fatty aldehydes or fatty acids. The invention additionally provides methods of using the above microbial organisms to produce a fatty alcohol, a fatty aldehyde or a fatty acid.
