Arthrobacter spp. 와 Pseudomonas putida 의 세포융합에 의한 난분해성 방향족 화합물 분해세균의 균주개량
Improvement of the Strains Degrading Recalcitrant Aromatic Compounds by Cell Fusion Between Arthrobacter spp. and Pseudomonas putida
초록
합성세제 분해능이 월등한 Pseudomonas putida 와 프탈산에스테르를 분해하는 Arthobacter spp. 의 세포융합을 통해 합성세제와 프탈산에스테르의 분해능을 모두 갖는 융합균주를 개발하였다. Ampicillin-Lysozyme-EDTA 에 의한 각 균주의 원형진체 생성율은 98.4%-99.9% 이었고 원형질체의 재생율은 5-8%이었다. Fusogen으로 40%PEG4000 을 이용하였을 때 효과적으로 융합이 이루어졌으며 융합율은
To develope the new strains of microorganisms having the degradative ability for various aromatic hydrocarbons. spheroplast cell fusions were performed with Arthrobacter spp. degrading phthalate ester and Pseudomonas putida degrading alkylbenzen sulfonate(ABS) and the characteristics of the fusants were investigated. The spheroplasts of P. putia KUD15 and Arthrobacter sp. were formed effectively by lysozyme-EDTA treatment and by Ampicillin-lysozyme-EDTA treatment. respectively. The Spheroplast formation frequency and the regeneration frequency of the strains were 98-99% and 5-8%, respectively. For cell fusion. 40% PEG6000 was used as a fusogenic agent and the formation frequencies of fusion product were
