 CDC - Streptomyces bikiniensis Bacteremia
We describe the isolation of Streptomyces bikiniensis from multiple blood cultures in a single patient over the course of 1 week, further illustrating that Streptomyces is pathogenic and a cause of bacteremia even in the absence of overt clinical symptoms and risk factors.
The Streptomyces isolate was susceptible to vancomycin, amikacin, cotrimoxazole, erythromycin, cephazolin, and tetracycline and was resistant to ampicillin, penicillin, oxacillin, and clindamycin.
Streptomyces isolated from blood cultures should not be dismissed as contaminants without careful consideration of the clinical situation; the isolation of Streptomyces from repeat blood cultures strongly suggests a pathogenic role.

 Streptomyces
The genome of Streptomyces coelicolor has recently been fully sequenced at the Sanger centre in the UK, Nature 417, 141 -147, Bentley et al (1)
S coelicolor is a soil bacterium that has many different metabolic processes and biotransformations that allow it to live under a wide range of conditions in the soil and use a wide range of metabolic pathways to, for example, degrade insoluble remains of other organisms.
So we see that functionality and DNA has been added to genome of S coelicolor since its divergence from M tuberculosis and C diphtheriae; evidence which stand in contradiction to the claim that information cannot be added to the genome through evolution.

 CiteULike: Posttranslational processing of the xylanase Xys1L from Streptomyces halstedii JM8 is carried out by ...   (Site not responding. Last check: )
The xylanase Xys1L from Streptomyces halstedii JM8 is known to be processed extracellularly, to produce a protein of 33.7 kDa, Xys1S, that retains catalytic activity but not its cellulose-binding capacity.
The genes of two of these extracellular serine proteases, denominated SpB and SpC, were cloned from Streptomyces lividans 66 (a strain commonly used as a host for protein secretion), sequenced, and overexpressed in S. lividans; both purified proteases were able to process Xys1L in vitro.
The involvement of serine proteases in xylanase processing-degradation in vivo was demonstrated by co-expression of the xylanase gene (xysA) and the gene encoding the serine protease inhibitor (SLPI) from S. lividans.

Streptomyces rimosus K-0K-02 had serine alkaline protease, leucine aminopeptidase, and trypsin-like protease that were stable from pH 4.5 to 9.0 (Renko et al., 1981, 1989; Vitale et al., 1986).
Streptomyces rimosus K-0K-02 had a leucine aminopeptidase stable up to 70°C and had a trypsin-like protease that was stable up to 40°C (Vitale et al., 1986; Renko et al., 1989).

 Discussion
Streptomyces that produce antibiotics are generally found in soil.
This does not mean that Streptomyces was not present in the other samples, but perhaps our protocol was not the best method for isolating Streptomyces in natural soil samples.
The other samples of Streptomyces may in fact be antibiotic producing, but more testing is required to discover the variety of strains present and the strength of each antibiotic produced by Streptomyces.
