16S phylogeny of the Streptomycetaceae Why? Hypothesis those claiming the same antibiotic in different species “are mistaken in species identification or the nature of the antibiotic” Krassilnikov5 best producers of natural product antibiotics are members of the actinomycetes, and according to Hugenholz et al. (1998), approximately 30% or more of these have been discovered at one time or another. This has been the result of some fifty years worth of intense antibiotic screening programs conducted by pharmaceutical industry natural products scientists Strohl, 2004 To address this hypothesis, for Streptomyces, need to be able to address the relationship of strains to one another For example, a survey of the literature linked the “species” names Streptomyces antibioticus, S. griseus and S. hygroscopicus, with the production of 13, 32, and 46 different structural types of natural products, respectively. Examples of compounds produced by strains characterized as S. hygroscopicus include rapamycin, spectinomycin, bialophos, hygromycin, and a variety of polyethers.Strohl 2004

16S phylogeny of the Streptomycetaceae Tree generation • Downloaded 7,610 pre-aligned streptomycete 16S from RDP in Genbank FASTA format (in 2010) – remove 17 ambiguous sequences • Edit labels to exclude invalid characters and consist of a unique numeric code, the species name, the strain name, the culture collection number and the Genbank sequence code • Generate the pairwise alignment distance matrix • Calculate the RDP alignment distance matrix and compare the pairwise and multiple alignment distances • Repeat • Manually re-align and calculate the distance matrix • Calculate a tree (NJ-Jukes & Cantor initially then Maximum Likelihood) • Sort the sequences to tree order • Until the total distance in the distance matrix stops decreasing
