Doxorubicin is an anthracycline-family polyketide compound with a very potent anti-cancer activity, typically produced by Streptomyces peucetius. In order to increase doxurubicin productivity, a semi-industrial doxorubicin-producing Streptomyces strain named BR-Dox was cultured in a R2YE liquid medium containing CaCO3, and then converted to a cell wall-free protoplast using lysozyme treatment method, followed by PEG-mediated cell wall regeneration.
