Propanediol utilization (PDU) operon in PAL227 and PAL113 encodes for key proteins in the production of short-chain fatty acids. The heatmap of gene frequency is based on the annotations of P. americana isolate genomes and publicly available Lachnospiraceae genomes. The colors in the rows indicate the host from which each genome was isolated. Complete PDU operon maps of PAL113 and PAL227 are illustrated in supplementary figure S4 (Supplemental Materials online).
