Fig. 2: Expected and observed label distribution in GC-MS measurements of amino- and fatty acids.
From: Chemoorganoautotrophic lifestyle of the anaerobic enrichment culture N47 growing on naphthalene
The expected A and observed B results of experiments with 13C-labeled naphthalene and the expected C and observed D results of experiments with 13CO2. Red lines indicate an expected increase by 2 mass units resulting from degradation of fully labeled naphthalene into acetyl-CoA and the position of the two labeled carbon atoms. A thin red line indicates that the found labeling is not as high as it was expected. Blue dots indicate an increase by 1 mass unit (M+1) and the position of the labeled carbon atom. The columns next to the amino or fatty acids show the measured ratio of M+2 (red) and M+1 (blue). With 1: naphthalene, 2: acetyl-CoA, 3: exemplary fatty acid, 5: alanine.
