Fig. 4From: Integrated isotope-assisted metabolomics and 13C metabolic flux analysis reveals metabolic flux redistribution for high glucoamylase production by Aspergillus niger The distribution of metabolites pools between A. niger DS03043 (left column) and CBS513.88 (right column). The bar graphs with black frames indicate the significant difference (P value <0.05) in pool size of metabolites for the two strains. All metabolite pool sizes were measured in at least triplicate measurements. The P values were obtained from two-tailed T test statistical analyses. The upper and lower numbers represent the absolute flux values (mmol/gDCW h) through each reactions in A. niger DS03043 and CBS513.88 respectivelyBack to article page
