Genome-Based Taxonomic Classification of the Phylum Actinobacteria

The application of phylogenetic taxonomic procedures led to improvements in the classification of bacteria assigned to the phylum Actinobacteria but even so there remains a need to further clarify relationships within a taxon that encompasses organisms of agricultural, biotechnological, clinical, and ecological importance. Classification of the morphologically diverse bacteria belonging to this large phylum based on a limited number of features has proved to be difficult, not least when taxonomic decisions rested heavily on interpretation of poorly resolved 16S rRNA gene trees. Here, draft genome sequences of a large collection of actinobacterial type strains were used to infer phylogenetic trees from genome-scale data using principles drawn from phylogenetic systematics. The majority of taxa were found to be monophyletic but several orders, families, and genera, as well as many species and a few subspecies were shown to be in need of revision leading to proposals for the recognition of 2 orders, 10 families, and 17 genera, as well as the transfer of over 100 species to other genera. In addition, emended descriptions are given for many species mainly involving the addition of data on genome size and DNA G+C content, the former can be considered to be a valuable taxonomic marker in actinobacterial systematics. Many of the incongruities detected when the results of the present study were compared with existing classifications had been recognized from 16S rRNA gene trees though whole-genome phylogenies proved to be much better resolved. The few significant incongruities found between 16S/23S rRNA and whole genome trees underline the pitfalls inherent in phylogenies based upon single gene sequences. Similarly good congruence was found between the discontinuous distribution of phenotypic properties and taxa delineated in the phylogenetic trees though diverse non-monophyletic taxa appeared to be based on the use of plesiomorphic character states as diagnostic features.

“…Streptomyces azureus ATCC 14921 is categorized in the blue-spore Streptomyces cyaneus cluster and is known to be a thiostrepton producer ( 4 ). The thiostrepton resistance gene ( tsr ), which is a selective marker often used in the genetic engineering of actinomycetes, was isolated from the strain ( 5 , 6 ).…”

Lomofungin is a new antimicrobial agent obtained from the culture broth of Sireptomyces lomondensis sp. n. UC-5022. Lomofungin is an acidic, olive-yellow, crystalline compound which inhibits, in vitro, a variety of pathogenic fungi, yeasts, and gram-positive and gram-negative bacteria. Streptomyces lomondensis sp. n. produces a new antibiotic designated lomofungin [referred to in U.S. Patent 3,359,165 as lomondomycin (U-24,792)]. Bergy (unpublished data) characterized lomofungin as an acidic, olive-yellow, crystalline compound with the molecular formula C15H1oN206 and a molecular weight of 314. The compound is soluble in dimethyl formamide, alkaline water, acidic acetone, and acidic methyl ethyl ketone. It is only slightly soluble in water, methanol, cyclohexane, acetone, ether, and ethyl acetate. Lomofungin does not melt below 320 C. This paper describes the organism, the fermentation conditions, the paper chromatogram characterization, and some of the biological properties of the antibiotic. MATERIALS AND METHODS Culture. S. lomondensis was characterized by the methods cited by Dietz (2).
