Escherichia coli K12의 Lysine 요구성 돌연변이체의 분리
강판조 ( Pan Jo Kang ),이형환 ( Hyung Hoan Lee ) 건국대학교 기초과학연구소 1980 理學論集 Vol.6 No.-
Escherichia coli K12을 nitrosoguanidine으로 처리한 후에 Auxotrophic mutant 들을 분리하였다. 1. 영양소로서 아미노산 lysine을 요구하는 4개의 돌연변이체를 분리하여 냈다. 2. 위의 4개의 돌연변이체는 또한 penicillin 저항성을 가지고 있다.
Escherichia coli RY13의 Auxotrophic Mutant의 분리와 요구성 연구
李炯煥,姜判祚 건국대학교 교육대학원 1982 敎育論叢 Vol.2 No.-
Escherichia coli RY13 were cultivated in Nutrient broth at 37℃ and mutagenized with Nitrosoguanidine. From the mutagenized cells, 47 auxotrophic mutants were selected. Four mutants out of 47 auxotrophs did not require any amino acids at all, but 43 mutants out of them required all kinds of amino acids.
테트라히드로디시크로펜타디엔의 아다만탄으로의 전위반응에 대한 금속희토류교환 제올라이트 촉매의 활성과 선택성
趙容錫,姜判祚 西原大學校 基礎科學硏究所 1992 基礎科學硏究論叢 Vol.6 No.-
Bifunctional catalysts metals on supported on Y zeolite exchanged by rare-earth ion (RE*), have high catalystic activity for the synthesis of adamantane from tetrahydrocyclopentadiene(TCD) in the presence of hydrogen and hydrogen chloride. These catalysts were prepared by the impregnation of metal salts with RE-Y zeolite. Their activity was measured by the batch reactor system. The TCD conversion consists of two reactions, the rearrangement of TCD to adamantane and hydrocracking to ring opening products(C??H?? isomer). No tarry materials were produced in the TCD conversion over bifunctional catalysts in the presence of hydrogen. The activity of metals supported on RE-Y for hydrocracking of TCD varied in proportion to the %d character of the metals. While for the rearrangement, it was independent of the %d character of the metals. In the case of a binary system of platinium and Rhenium the maximum activity for both reaction was observed at Re/(re+Pt) = 0.24. Furthermore poisoning by atomic sulfure on a bifunctional catalyst, the activity for the hydrocracking of TCD was depressed.
Isolation of Lysine-requiring Auxotrophic mutants of Escherichia coli K12

Escherichia coli K12을 nitrosoguanidine으로 처리한 후에 Auxotrophic mutant들을 분리하였다. 1. 영양소로서 아미노산 lysine을 요구하는 4개의 돌연변이체를 분리하여 냈다. 2. 위의 4개의 돌연변이체는 또한 penicillin 저항성을 가지고 있다. 1.Four auxotrophic mutants of Escherichia coli K12 requiring lysine as a nutritional factor were isolated from minimal salts media. 2. The four mutants are also penicillin-resistant.
