Analysis of P. pastoris differential gene expression between SDEM and SDEG culture. (A) Differential gene expression between P. pastoris SDEM and SDEG culture, analyzed by the ‘R’ (DESeq) software. (B) Metabolic pathway analysis of differentially expressed genes between SDEM and SDEG culture. Genes denoted by red font are up-regulated in SDEM condition compared to SDEG condition. Genes denoted by green font are down-regulated.
