        The increase of CO2 in the atmosphere by fossil-fuel combustion has been recognized as a major cause of global warming. Thus many studies on CO2 removal from the combustion gas have been performed, and recently the techniques for biological CO2 fixation by photoautotrophs have also been developed, In this study, extensive screening was conducted to obtain micoorganism with high capability in fixing CO2, and its characteristics was investigated. As a result, a chemoautotrophs identified as a Aeromonas sp. strain JS-1 was isolated from the fresh water. The isolated strain used the molecular hydrogen and CO2 as an energy and a carbon source, respectively. Growth characteristics, which will be used in the development of a continuous culture system related in CO2 fixation, were examined in batch cultivation under conditions of various CO2 and NaCl concentrations, temperature, and pH. The results of the examination showed that the isolated strain had a good growth to high CO2 concentration(40%), indicating applicable in removing CO2 discharged from industries.

      • 단기배양을 통한 말초혈액 CD34 양성세포의 체외증폭

        박상준,김철희,배광봉,김현수,김종숙,윤환중,조덕연,김삼용 충남대학교 의과대학 지역사회의학연구소 1997 충남의대잡지 Vol.24 No.1

        Background: It is suggested that clinical practice in the areas of bone marrow transplantation and gene therapy might rely on the ex vivo expansion of hematopoietic stem/progenitor cells. However, the condition for ex vivo expansion of hematopoietic progenitor cells is not well established. The authors pursued a series of experiments to define the proper conditions for the expansion of hematopoietic cells in the short-term liquid suspension culture of mobilized peripheral blood CD34+ cells. Methods: 1.0ml cultures were initiated with 9×10^3 PB CD34+ cells, which were isolated from PB mononuclear cells (MNCs) by high-gradient cell sorting, in 12 well plates with the various combinations of hematopoietic growth factors(HGF). The following recombinant human HGFs were used: stem cell factor(SCF) 100ng/ml, granulocyte colony-stimulating factor(G-CSF) 100ng/ml, GM-CSF(granulocyte, macrophage colony-stimulating factor) 100ng/ml, interleukin-1 beta(IL-1B) 1ng/ml, interleukin-3(IL-3) 20ng/ml, interleukin-6 (IL-6) 100ng/ml. At the end of culture, colony-forming cells were evaluated by semisolid clonogenic assay. Results: 1) Using the high-gradient magnetic sorting system, CD34^+ cells were isolated with a yield of 40 3% 2) In 7 day culture of PB CD34^+ cells(9×10^3 cells), nucleated cells expanded mean 10×10^3(range, 9 to 20×10^3) with the addition of SCF alone, 35×10^3(range, 10 to 60×10^3) with SCF plus G-CSF plus GM-CSF, and 130×10^3(range, 40 to 300×10^3) with the combination of SCF, G-CSF, IL-1, IL-3, IL-6, GM-CSF. In 14 day culture, nucleated cells expanded 10×10^3 to 1,860×10^3 with combination of human hematopoietic growth factors. 3) In 10 day culture without medium change of PB CD34^+ cells, CFU-GM numbers expanded 16. 5 fold(range, 7 to 59 fold) with the addition of SCF plus G-CSF plus Il-1 plus IL-3, 31.3 fold(range, 20.5 to 101.1 fold) with the combination of SCF, G-CSF, IL-1, IL-3, GM-CSF. In 14 day culture with or without medium change of PB CD34^+ cells was inferior to 10 day culture for CFU-GM expansion. 4) There was no significant difference for CFU-GM expansion between five growth factors(SCF,G-CSF,IL-1,IL-3,GM-CSF) and six growth factors(five growth factors plus IL-6). Conclusion: The authors could confirm that short-term suspension culture of peripheral blood CD34+ cells could expand hematopoietic progenitor cells. Ten-day culture with medium change of CD34+ cells with the addition of five growth factors, i.e. SCF, G-CSF, IL-1B, IL-3, and GM-CSF, might be the most efficient in this system.
