  • Patent number: 10494654
    Abstract: A microbial cell is used for producing at least one fatty acid ester, wherein the cell is genetically modified to contain (i) at least one first genetic mutation that enables the cell to produce at least one fatty acid and/or acyl coenzyme A (CoA) thereof by increased enzymatic activity in the cell relative to the wild type cell of malonyl-CoA dependent and malonyl-ACP independent fatty acyl-CoA metabolic pathway, wherein the fatty acid contains at least 5 carbon atoms; and (ii) a second genetic mutation that increases the activity of at least one wax ester synthase in the cell relative to the wild type cell and the wax ester synthase has sequence identity of at least 50% to a polypeptide of SEQ ID NO: 1-8 and combinations thereof or to a functional fragment of any of the polypeptides for catalyzing the conversion of fatty acid and/or acyl coenzyme A thereof to the fatty acid ester.

  • Patent number: 4690897
    Abstract: Method for transforming anaerobic microorganisms. Anaerobic microorganisms are induced to form L-forms. Genetic material capable of inducing the desired phenotype is introduced into the L-forms, after which the L-forms may be caused to regenerate their cell wall. These methods are also useful for obtaining desired biological products. Additionally, shuttle vectors capable of transforming both aerobic and anaerobic microorganisms are set forth.
