  • Publication number: 20110289632
    Abstract: Isolated genes and amino acid sequences encode methylketone synthase 2 (MKS2) enzymes from tomato plants, including, ShMKS2 and SlMKS2. When expressed recombinantly in bacteria and other host cells, the MKS2 enzymes produce methylketones of various carbon chain lengths ranging from C7 to C20 from 3-ketoacyl intermediate substrates. Methylketones are known to have important roles in protecting plants against pests, and also as flavor compounds, and can be used as stockfeed in the chemical industry.

  • Publication number: 20100196964
    Abstract: The present invention relates to a process for the production of an aqueous glucose solution from maize or maize kernels. The invention also relates to a glucose solution obtainable by this process, and to its use for the production of organic compounds. The process according to the invention comprises: a) fractionating dry milling of maize kernels, where the maize kernels are separated into a maize-starch-comprising endosperm fraction and a high-oil germ fraction and, if appropriate, a bran fraction; b) enzymatic liquefaction and saccharification of the maize starch in an aqueous suspension of the endosperm fraction, which gives an aqueous glucose solution comprising maize gluten; and c) depletion of the maize gluten and, if appropriate, any bran present from the aqueous glucose solution.

  • Publication number: 20100190225
    Abstract: Provided is a method of producing D-psicose using a D-psicose epimerase derived from Agrobacterium tumefaciens. Provided are a protein having an amino acid sequence of SEQ ID NO:1 and having a psicose 3-epimerase activity, a gene encoding the protein, a recombinant expression vector containing the gene, and a method of producing D-psicose by reacting the protein produced on a mass scale with D-fructose. The method of producing D-psicose is an environmentally friendly method using a new enzyme, in which an inexpensive substrate is used, and the activity of the enzyme can be retained for a prolonged time period. Thus, the method can be efficiently used for the mass production of D-psicose.

  • Publication number: 20100184173
    Abstract: A non-naturally occurring microbial organism having a methyl ethyl ketone pathway includes at least one exogenous nucleic acid encoding a methyl ethyl ketone pathway enzyme expressed in a sufficient amount to produce methyl ethyl ketone. The methyl ethyl ketone pathway includes a ?-ketothiolase, a ?-ketovalerate decarboxylase and an enzyme selected from the group consisting of a ?-ketovaleryl-CoA hydrolase and a ?-ketovaleryl-CoA transferase. Alternatively, the methyl ethyl ketone pathway includes a 2-methylacetoacetyl-CoA thiolase, a 2-methylacetoacetate decarboxylase and an enzyme selected from the group consisting of a 2-methylacetoacetyl-CoA hydrolase and a 2-methylacetoacetyl-CoA transferase. Either pathway can further include a methyl ethyl ketone reductase to produce 2-BuOH. A method for producing methyl ethyl ketone or 2-BuOH includes culturing these non-naturally occurring microbial organisms under conditions, and for a sufficient period of time, to produce methyl ethyl ketone or 2-BuOH.

  • Publication number: 20100137647
    Abstract: Methods are disclosed for forming heptan-4-one, and, optionally, heptan-4-ol, from fermentable sugars. The sugars are fermented using a bacteria or yeast that predominantly forms butyric acid. The butyric acid is subjected to catalytic ketonization conditions to form heptan-4-one, with concomitant loss of water and carbon dioxide. The heptan-4-one can be subjected to catalytic hydrogenation to form heptan-4-ol, an either of these can be included in gasoline compositions. In one aspect, the fermentable sugars are derived from lignocellulosic materials such as wood products, switchgrass, or agricultural wastes, which are delignified to form lignin, cellulose and hemicellulose. The cellulose and hemicellulose can be depolymerized to form glycose and xylose, either or both of which can be fermented by the bacteria.
