The present disclosure relates to a method for the incorporation of formaldehyde into biomass comprising the following enzymatically catalyzed steps: (1) condensation of pyruvate with formaldehyde into 4-hydroxy-2-oxobutanoic acid (HOB); (2) amination of the thus produced 4-hydroxy-2-oxobutanoic acid (HOB) to produce homoserine; (3) conversion of thus produced homoserine to threonine; (4) conversion of the thus produced threonine into glycine and acetaldehyde or acetyl-CoA; (5) condensation of the thus produced glycine with formaldehyde to produce serine; and (6) conversion of the thus produced serine to produce pyruvate, wherein said pyruvate can then be used as a substrate in step (1). The disclosure also relates to enzymes for catalyzing the corresponding enzymatic reactions and recombinant microorganisms which express the enzymes for catalyzing the corresponding enzymatic reactions.

Provided herein are compositions with enhanced protein content, proteins with high solubility, protein combinations and methods for the preparation thereof.

The present invention relates to the identification of a new class of fatty acid decarboxylases and its uses, in particular for producing alkanes/alkenes from fatty acids.

The present application provides a process for the preparation of -methylene--butyrolactone, said process comprising the steps of: a) acetylating the C1-hydroxyl group of isoprenol to yield isoprenyl acetate; b) forming 4-acetoxy-2-methylene-butan-1-ol from said isoprenyl acetate by whole cell biotransformation, said step comprising: i) contacting a cell (CB) with a culture medium containing said isoprenyl acetate or with a culture medium contiguous with an organic phase containing said isoprenyl acetate under conditions that enable the cell to form 4-acetoxy-2-methylene-butan-1-ol from isoprenyl acetate; and, ii) optionally isolating the resultant 4-acetoxy-2-methylene-butan-1-ol, wherein said cell (CB) exhibits activity of at least one alkane monooxygenase enzyme which catalyzes the formation of 4-acetoxy-2-methylene-butan-1-ol from isoprenyl acetate; c) oxidizing said 4-acetoxy-2-methylene-butan-1-ol to yield 4-acetoxy-2-methylene butyric acid; and, d) converting said 4-acetoxy-2-methylene butyric acid to -methylene--butyrolactone by hydroxylysis to -hydroxy--methylenebutyric acid and subsequent cyclization of said -hydroxy--methylenebutyric acid.

The invention provides non-naturally occurring microbial organisms containing butadiene or 2,4-pentadienoate pathways comprising at least one exogenous nucleic acid encoding a butadiene or 2,4-pentadienoate pathway enzyme expressed in a sufficient amount to produce butadiene or 2,4-pentadienoate. The organism can further contain a hydrogen synthesis pathway. The invention additionally provides methods of using such microbial organisms to produce butadiene or 2,4-pentadienoate by culturing a non-naturally occurring microbial organism containing butadiene or 2,4-pentadienoate pathways as described herein under conditions and for a sufficient period of time to produce butadiene or 2,4-pentadienoate. Hydrogen can be produced together with the production of butadiene or 2,4-pentadienoate.
