Transfer of the waterfall source isolate Pectobacterium carotovorum M022 to Pectobacterium fontis sp. nov., a deep-branching species within the genus Pectobacterium Oulghazi, Said and Cigna, Jérémy and Lau, Yin Yin and Moumni, Mohieddine and Chan, Kok Gan and Faure, Denis,, 69, 470-475 (2019), doi = https://doi.org/10.1099/ijsem.0.003180, publicationName = Microbiology Society, issn = 1466-5026, abstract= Pectobacterium carotovorum M022T has been isolated from a waterfall source in Selangor district (Malaysia). 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., language=, type=
