  • Patent number: 10011854
    Abstract: The present disclosure relates to an engineered microbe capable of improved productivity of fatty acid or fatty acid derivative. An NAD+-dependent 3-oxoacyl-ACP reductase or NAD+-dependent 3-oxoacyl-CoA reductase replaces or supplements the native NADP+-dependent 3-oxoacyl-ACP reductase so as to utilize the higher availability of NAD+ rather than NADP+ in the cell. Higher production, yield and titer of fatty acids are therefore obtained. Such microbes can be combined with other mutations to further improve yield of fatty acids or fatty acid derivatives.

  • Patent number: 9988649
    Abstract: The present invention relates to processes for producing ethanol from lignocellulosic hydrolysates comprising hexoses, pentoses and acetic acid, whereby genetically modified yeast cells are use that comprise an exogenous gene encoding an acetaldehyde dehydrogenase and a bacterial gene encoding an enzyme with NAD+-linked glycerol dehydrogenase activity.

  • Patent number: 9957533
    Abstract: Provided is a mutant of propionyl-CoA transferase from Clostridium propionicum that can convert lactate into lactyl-CoA with high efficiency in a method of preparing a polylactate (PLA) or PLA copolymer using microorganisms. Unlike conventional propionyl-CoA transferase which is weakly expressed in E. coli, when a mutant of propiony-CoA transferase from Clostridium propionicum is introduced into recombinant E. coli, lactyl-CoA can be supplied very smoothly, thereby enabling highly efficient preparation of polylactate (PLA) and PLA copolymer.
