Synthetic methylotrophy to liquid fuels and chemicals

1. A method for producing a metabolite, comprising growing a non-naturally occurring microbe in a medium comprising methanol, wherein the non-naturally occurring microbe expresses heterologous methanol dehydrogenase (MDH) and one or more heterologous ribulose monophosphate (RuMP) pathway enzymes, wherein the heterologous MDH is Bacillus stearothermophilus MDH, wherein the one or more heterologous RuMP pathway enzymes comprise Bacillus methanolicus 3-hexulose-6-phosphate synthase (HPS) and Bacillus methanolicus 3-hexulose-6-phosphate isomerase (PHI), wherein the non-naturally occurring microbe is derived from Escherichia or Corynebacterium , and wherein the methanol contributes to at least 40% of the carbon source for the non-naturally occurring microbe, whereby the metabolite is produced.

2. The method of claim 1 , wherein the metabolite is selected from the group consisting of 4-carbon chemicals, diacids, 3-carbon chemicals, higher carboxylic acids, alcohols of higher carboxylic acids, and polyhydroxyalkanoates.

3. The method of claim 1 , wherein the metabolite is n-butanol.

4. The method of claim 1 , further comprising modifying the gene of heterologous MDH or any one of the one or more heterologous RuMP pathway enzymes, whereby the yield of the metabolite is improved.

5. The method of claim 1 , further comprising fixing CO 2 .

6. The method of claim 1 , wherein the non-naturally occurring microbe is grown at a temperature higher than 37° C.

7. The method of claim 1 , wherein the non-naturally occurring microbe is grown anaerobically.

8. The method of claim 1 , whereby at least 40% of the carbon in the metabolite is derived from the methanol.

9. The method of claim 1 , wherein the metabolite is an amino acid or tricarboxylic acid (TCA) intermediate having a carbon at the fourth position derived from the methanol, wherein the TCA intermediates are selected from the group consisting of succinate, succinyl-CoA, alpha-ketoglutarate, isocitrate, citrate, oxaloacetate, malate and fumarate.

10. The method of claim 1 , further comprising producing a metabolite by the non-naturally occurring microbe, and incorporating carbon from methanol into the metabolite, wherein at least 40% of the carbon in the metabolite is derived from the methanol.

11. The method of claim 1 , wherein the non-naturally occurring microbe is derived from Escherichia.

12. The method of claim 1 , wherein the non-naturally occurring microbe contains a deletion of an frmRAB operon.

13. The method of claim 1 , wherein the non-naturally occurring microbe expresses one or more heterologous pentose-phosphate pathway (PPP) enzymes.

14. The method of claim 13 , wherein the one or more heterologous PPP enzymes consist of heterologous phosphofructokinase (PFK), heterologous fructose bisphosphate aldolase (FBA), heterologous transketolase (TKT), heterologous fructose/sedoheptulose biphosphatase (GLPX), heterologous transaldolase (TAL), heterologous ribose-5-phospate isomerase (RPI) and heterologous ribulose phosphate epimerase (RPE).

15. The method of claim 1 , wherein the non-naturally occurring microbe expresses one or more heterologous cyclic formaldehyde dissimilation enzymes.

16. The method of claim 15 , wherein the one or more heterologous cyclic formaldehyde dissimilation enzymes consist of heterologous glucose-6-phosphate isomerase (PGI), glucose-6-phosphate-1-dehydrogenase (ZWF), 6-phosphogluconolactonase (PGL), and 6-phosphogluconate dehydrogenase (GND).
