  1. aIdentification results on genus and species level; species identifications are only tentative
  2. bThe frequency of identified isolates based on rep-clustering and partial 16S rRNA gene sequence analysis with cut-off value of 98.5 % similarity with type strains of validly published prokaryotic names in EZTaxon database. The percentage of total number of isolates of each genus is listed in the last column
