초록

독소루비신 고 생산성 산업균주인 BR-Dox의 충분한 양의 세포를 얻어내기 위해 R2YE 배지를 사용하였으며, 방선균의 포자형성이 잘 일어나는 R2YE 배지의 각 성분별로 첨가한 결과, CaCO$_3$를 첨가하였을 때 인위적인 원형질체 유도에 적합한 양의 세포를 얻어낼 수 있었다. 독소루비신 생합성 능력이 향상된 균주를 선별하기 위해 BR-Dox를 배양하여 세포를 인위적으로 원형질체로 유도하여 세포벽을 재생시킨 결과, 특이적으로 독소루비신 색소로 추정되는 붉은 색을 많이 내는 콜로니를 선별하여 정성 및 정량분석을 수행하였다. 선별된 파생균주 BR-Dox4와 BR-Dox6의 경우 TLC 정성분석 및 HPLC 정량분석 결과, BR-Dox에 비해 각각 25.2%, 12.2%의 생산성이 향상되었다. 본 연구결과는 인위적 원형질체 도입과 세포벽 재생을 통한 새로운 개념의 방선균 균주개량 방법을 제시하고, 이를 이용한 독소루비신 고생산성 균주개발의 가능성을 제시하였다.

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 CaCO$_3$, and then converted to a cell wall-free protoplast using lysozyme treatment method, followed by PEG-mediated cell wall regeneration. Among several protoplast-regenerated Streptomyces BR-Dox strains, two independent isolates named BR-Dox4 and BR-Dox6 were visually selected using thin layer chromatography (TLC) based on the pigment overproducing phenotype. Comparing with Streptomyces BR-Dox parental strain, two protoplast-regenerated strains, BR-Dox4 and BR-Dox6 exhibited 25.2％ and 12.2％ higher doxorubicin productivity analyzed by high pressure liquid chromatography (HPLC), respectively. This result suggests that a protoplast-regeneration of an antibiotics-producing Streptomyces strain should be a promising strain development approach for antibiotics overproduction in Streptomyces species.
