PROPOSAL OF 6 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 [= DSM 201431), Aureobacterium schleiferi sp. nov. (type strain, IFO 15075 [= DSM 204891), 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.
