Using genomic and phenotypic tests, we re-examined the taxonomical position of this strain. Based on 14 concatenated housekeeping genes (fusA, rpoD, rpoS, acnA, purA, gyrB, recA, mdh, mtlD, groEL, secY, glyA, gapA and rplB), multi-locus sequence analysis revealed that strain M022T falls into a novel clade separated from the other Pectobacterium species. The in silico DNA–DNA hybridization and average nucleotide identity values were lower than the 70 and 95 % threshold values, respectively. In addition, by combining genomic and phenotypic tests, strain M022T may be distinguished from the other Pectobacterium isolates by its incapacity to grow on d(+)-xylose, l-rhamnose, cellobiose and lactose. Strain M022T (=CFBP 8629T=LMG 30744T) is proposed as the type strain of the Pectobacterium fontis sp. nov., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.003180
