From: Functional expression and evaluation of heterologous phosphoketolases in Saccharomyces cerevisiae
Phosphoketolase activity correlates with increased acetate accumulation and reduced growth rate and biomass formation. a Maximal acetate accumulation and maximum specific growth rate measured in cultivations of xfpk expressing strains. b Acetate accumulation and optical density measurements during whole growth phase. The legends refer to the xfpk genes expressed in strains AB1, AB3, AB5 and AB6. pSP-GM1 harboring strain AB10 served as negative control. Triangles correspond to acetate measurements and circles optical density. Strains were grown in shake flasks with minimal medium containing 2% glucose. The results shown are averages from three biological replicates; error barss indicate the standard deviation
