a Fold enrichment of strains relative to Escherichia in the Jewel Lake enrichment. Open symbols are strains that use carbon sources the Escherichia cannot utilize. b Nitrite and ammonium concentrations of the Jewel Lake enrichment alone (dark gray symbols) or bioaugmented with Klebsiella (orange symbols) or Pseudomonas (blue symbols) with D-glucose, citrate or L-sorbose as the sole carbon source. c For genomes that encode the L-sorbose utilization genes (sorABE), we show how often they are expected to be nitrite accumulators or nitrate ammonifiers (DNRA) based on the presence or absence of respiratory nitrate reductase genes (napA, narG) and respiratory nitrite reductase genes (nirS, nirK, nrfA). Because L-sorbose utilization is best studied in Enterobacteriaceae, we show results separately for this group than for other prokaryotes (Other). We found no predicted dentrifiers that have the sorABE genes. Data are from 27,941 prokaryotic genomes on Annotree (“Materials and methods”).
