Fig. 6From: Metabolic engineering of methylotrophic Pichia pastoris for the production of β-alanineThe effects of strengthening PEP carboxylation on β-alanine production. A Growth profiles of recombinant strains; B β-alanine production in recombinant strains at the end of fermentation. Three parallel flasks are tested for each strain.
