Streptomyces

How does an antibiotic-producing Streptomyces sp. prevent killing itself by its own antibiotics?

It would be resistant to its own antibiotic by not containing the antibiotic target. Of course I am not sure how the Streptomyces sp. antibiotic works.

the Streptomyces genus produces more than 500 types of antibiotics, with a lot of different targets. But considering that some inhibit such basic processes like protein synthesis, I would say it is much more probable that they simply have an intracellular enzyme that breaks down the antibiotic.

I guess that Streptomyces have their own beta-lactamase :D

not all antibiotics have the beta-lactam ring...
