Three actinomycete strains isolated from soil, ‘
Streptomyces candidus subsp.
azaticus’ IFO 13803
T (T=type strain) and ‘
Nocardiopsis streptosporus’ IFO 14362
T were found to contain both LL- and
meso-2, 6-diaminopimelic acid (A
2pm) in their cell wall peptidoglycans and supposed to belong to new members of
Streptomyces, yielded by unification of the genus
Kitasatosporia with the genus
Streptomyces. Based on the phenetic and DNA-DNA hybridization studies, these strains were considered to belong to new species of the genus
Streptomyces. We propose the names
Streptomyces cochleatus sp. nov. for the species represented by the soil isolate M-5
T (=IFO 14768
T) and
S. paracochleatus sp. nov. for the soil isolate M-13
T (=IFO 14769
T), and
S. azaticus sp. Nov. for strain IFO 13803
T. ‘
Nocardiopsis streptosporus’ IFO 14362
T and ‘
Kitasatosporia brunnea’ IFO 14627
T were included in
S. phosalacinea. ‘
K. melanogena’ IFO 14327
T, ‘
K. cystarginea’ IFO 14836
T and ‘
K. kifunense’ IFO 15206
T were new species belonging to the genus
Streptomyces. ‘
K. clausa’ IFO 15240
T was supposed to belong to a maduromycete. ‘
K. papulosa’ and ‘
K.
grisea’ are synonymous, and should be reclassified as a species belonging to the cluster consisting of original
Streptomyces species.
