“烟草超氧化物歧化酶(SOD)的提取”是华南农业大学生物系光合作用研究室受广东省南雄县烟草研究所委托的研究项目。经过8个多月的研究之后,于1993午3月通过广东省高教局科技成果鉴定。该项研究以烟草低次等烟叶为原料,采用生物化学方法提取 SOD,得到了酶结晶,该结晶达到了电泳纯,活力回收率达16%。通过研究,建立了烟草 Tobacco superoxide dismutase (SOD) extraction is a research project entrusted by Nanxiong County Tobacco Research Institute of South China Agricultural University. After more than eight months of research, in March 1993 by the Guangdong Provincial Higher Education Bureau scientific and technological achievements appraisal. In this study, low-level tobacco leaves were used as raw materials, and biochemical methods were used to extract SOD. The enzyme was crystallized and the crystal reached electrophoretic purity. The recovery rate of vitality reached 16%. Through research, tobacco was established
