Abstract: A plurality of isolated polynucleotide sequences encoding enzymes of the astaxanthin pathway is disclosed. The polynucleotides include: (i) a polynucleotide which encodes Phytoene dehydrogenase (crtI) and a first transcriptional regulatory sequence; (ii) a polynucleotide which encodes Beta-lycopene cyclase (lcy-B) and a second transcriptional regulatory sequence; (iii) a polynucleotide which encodes Beta-carotene ketolase (crtW) and a third transcriptional regulatory sequence; and wherein the first, second and third regulatory sequence are selected such that the expression of the Icy-B and the crtW is greater than a level of expression of the crtI. Methods of generating astaxanthin using the plurality of polynucleotide are also disclosed as well as bacterial cells comprising high levels of astaxanthin.

Abstract: A microorganism which is genetically modified so that it produces a first essential biomass precursor by metabolizing CO2 using a recombinant carbon fixation enzyme is disclosed. The microorganism produces a second biomass precursor by metabolizing an organic carbon source and not by metabolizing CO2. The microorganism does not use the organic carbon source for producing the first essential biomass precursor.

Abstract: An isolated microorganism is disclosed being genetically modified to express pyruvate formate lyase (PFL) or 2-ketobutyrate formate lyase, wherein acetyl-CoA of the microorganism is converted to pyruvate in the presence of formate in a single step reaction, wherein the net flux of the reaction is in the direction of pyruvate synthesis.Uses of the microorganism and products comprising same are also disclosed.
