Proposal of six new species in the genus Aureobacterium and transfer of Flavobacterium esteraromaticum Omelianski to the genus Aureobacterium as Aureobacterium esteraromaticum comb. nov.

Twelve strains placed in the genera Flavobacterium, Pseudomonas, and Aureobacterium, including soil isolates, were characterized taxonomically. On the basis of morphological, physiological, and chemotaxonomic data, as well as DNA-DNA hybridization data, we propose that 11 of these strains should be classified in the genus Aureobacterium as new combinations or new species, as follows: Aureobacterium esteraromaticum comb. nov. (type strain, IFO 3751 [= ATCC 8091]), Aureobacterium arabinogalactanolyticum sp. nov. (type strain, IFO 14344), Aureobacterium keratanolyticum sp. nov. (type strain, IFO 13309), Aureobacterium luteolum sp. nov. (type strain, IFO 15074 [= DMS 20143]), Aureobacterium schleiferi sp. nov. (type strain, IFO 15075 [= DMS 20489]), Aureobacterium terrae sp. nov. (type strain, IFO 15300), and Aureobacterium trichothecenolyticum sp. nov. (type strain, IFO 15077 [= JCM 1358]). Whereas the peptidoglycan type of members of this genus is considered to be B2beta, the new species A. keratanolyticum was shown to have a new peptidoglycan type, murein variation B2alpha. An emended description of the genus Aureobacterium is presented.
