Comparative analysis of 16S rRNA gene sequences showed that this bacterium displayed <95 % similarity to all described species of the genera of the family Alcaligenaceae. It grouped within the radiation of the genus Alcaligenes, but showed only 93.0–94.8 % similarity to type strains of members of this genus (Alcaligenes faecalis subsp. parafaecalis, 94.8 %; Alcaligenes faecalis subsp. faecalis, 94.2 %; Alcaligenes faecalis subsp. phenolicus, 93.4 %). This discrimination was supported by chemotaxonomic differences. The polyamine pattern consisted of the predominant compound putrescine, moderate amounts of spermidine and minor to trace amounts of spermine and cadaverine; 2-hydroxyputrescine was not detectable. The quinone system was ubiquinone Q-8 with minor amounts of Q-7. The polar lipid profile was composed of the major lipids diphosphatidylglycerol and phosphatidylethanolamine and moderate amounts of phosphatidylglycerol and an unknown phospholipid; minor lipids were also detected. The fatty acid profile, with large amounts of C16 : 0 and C17 : 0 cyclo and the absence of C12 : 0 2-OH as hydroxylated fatty acid, also differed significantly from those reported for Alcaligenes species. On the basis of these data, it is proposed that strain CCUG 53761AT represents a novel genus and species, for which the name Paenalcaligenes hominis gen. nov., sp. nov. is proposed. The type strain of Paenalcaligenes hominis is CCUG 53761AT =CCM 7698T.", }
