FIG 4.

Metabolic pattern of 3-(methylthio)-1-propanol and dimethyl disulfide at days 3 and 10. (a) Schematic depicting the metabolic profile of the microbiota. The red solid lines represent reactions carried out by Lactobacillus, black solid lines represent reactions carried out by Saccharomyces, green solid lines represent reactions by other genera, and the black dashed lines represent chemical reactions. Different colored areas show different modules. A, S, and E represent sulfur sources from aspartate, serine, and sulfite, respectively. M, cysteine to methionine; C, methyl cycle; L, methionine catabolism. (b) Heatmap showing the transcription level. The boxes on the left side of heatmap show the microbiota, and boxes on the right side represent corresponding enzymes. A complete list of the transcription levels of genes encoding enzymes can also be found in Table S3, Data Set S1, and Fig. S4. CoA, coenzyme A; PLP, pyridoxal phosphate.
