:1. Introduction
2. Results and Discussion
2.1. Combined Over-Expression of ZWF1 and SOL3 Improves the NADPH Supply and Thus Increases α-Farnesene Production in P. pastoris X33-30*
2.2. Inactivation of Glucose-6-Phosphate Isomerase Disturbs the Cell Growth and Thus Negatively Affects α-Farnesene Biosynthesis in P. pastoris X33-31
2.3. Low Intensity Expression of POS5 from S. cerevisiae Balances the NADPH/NADH Ratio and Thus Promotes α-Farnesene Biosynthesis in P. pastoris
2.4. Overexpression of Adenine Phosphoribosyltransferase Enhances the Precursor AMP Supply and Thus Increases the ATP Availability and α-Farnesene Production in P. pastoris
2.5. Deletion of NADH-Dependent Dihydroxyacetone Phosphate Reductase Elevates the Intracellular NADH Level and Thus Elevates the Intracellular ATP Level and α-Farnesene Production in P. pastoris
