青霉菌之种美国青霉素即配尼西林的生产量及供给量已较最近以前又增加了一倍,这不是说把工厂扩大了,或是机械增加了;它完全是实验研究的结果,是青霉菌胞子用紫外线照射后所得的新霉种,能产生惊人的改进。科学家的解释是:霉菌胞子和植物子实中的遗传因子,经过紫外线照射之后,起了一种尚未完全明白和不易预测的变化,因此从这种胞子或子实所生成的霉菌或植物,它们的性质也随着变更。X 光线也能够引起这种变化。青霉菌胞子连续数代经过这些处理,结果生成一新变种,可能使每C.C.培养液中含有近千个单位的青霉素;回忆在一九四○年英国学者最初研究时代,同容量中仅有两个单位。
The species of penicillin The production and supply of penicillin, that of niceptin, in the United States has doubled compared to its predecessor. This does not mean that the plant has been expanded or the machinery has been increased. It is entirely the result of experimental research that is green New molds obtained after the mold cells have been irradiated with UV light can produce amazing improvements. Scientists explain: mold cells and plant seed in the genetic factors, after UV irradiation, played a not yet fully understand and unpredictable changes, so from these cells or fruit mold or plant, they The nature is also changing. X rays can also cause this change. After several generations of Penicillium spores, these treatments led to the creation of a new variant that would probably contain nearly a thousand units of penicillin per CC broth; recalling that during the initial study of British scholars in 1940, only two A unit.
