ABSTRACT

The results of our experiments showed that the 5'-terminal sequences of 23S rRNAs can be used to distinguish different genera of actinomycetes, including the genera Streptomyces, Micromonospora, Amycolatopsis, and Saccharomonospora. There are small differences (<1%) among the sequences of some strains belonging to the genera Streptomyces (two strains) and Saccharomonospora (seven strains). On the basis of the results of morphological and biochemical analyses, strain 9022 belongs in the genus Saccharomonospora; however, there are distinct differences in the cell wall compositions and the 5' termini of the 23S rRNA sequences of this strain and members of the genus Saccharomonospora. Hence, strain 9022 cannot be classified in the genus Saccharomonospora.
