Effect of Nitrogen Source and Inorganic Phosphate Concentration on Methanol Utilization and PEX Genes Expression in Pichia pastoris

Figure 1

Quantitative analysis of the relative expression levels of PpDAK, PpDHAS, PpFLD, and PpFGH and PpPEX5, PpPEX14, PpPEX8, and PpPEX1 genes depending on the nitrogen source in the medium. MN medium contained ammonium sulphate and 1% methanol. MP medium contained proline and 1% methanol.
