Blocking competitive pathways and integration
of the Ehrlich pathway
in 26s rDNA sites to improve 2-PE production. (a–c) Cell growth,
2-PE titers, phenylacetate titers, and 2-PE yield of blocking competitive
pathways. (d) Screening of the productive strains based on 24-well
deep plate cultivations. (e,f) 2-PE titer and yield by further validating
productive strains with integration of the Ehrlich pathway in flask
cultivations. 1, strain po1fk4–1; 2, strain po1fk4–2; 3, strain po1fk4–3; 4,
strain po1fk4–4; 5, strain po1fk4–5; 6, strain po1fk4–6; 7, strain po1fk4–7; 8, strain po1fk4–8; 9, strain po1fk4–9; 10, strain po1fk4–10; 11, strain po1fk4–11; 12, strain po1fk4–12. All experiments were
performed in triplicate and error bars show standard deviation (SD).
