  4. Monofunctional alkylating agent n - methyl - n ' - nitro - n - nitrosoguanidine ( mnng ) is a widely spread environmental mutagen and carcinogen that targets dna and proteins to generate adducts. among the adducts, o6 - alkyl guanine is the predominant mutagenic lesion because of its mispairing properties, which can eventually lead to chromosomal aberrations, point mutations, and cell death. this lesion also appears to be involved in tumor initiation, particularly in gastric carcinogenesis

  7. The paper adopted the common breeding way by series of mutagen treating to the yeast ' s cell and spheroplast. finally, the excellent mutant 75l 3555 was obtained. its nature of the production was determined and it can product ethanol on the condition of 40 and have high fermentative speed and stable production. on the other hand, the test was made that the best fermentative condition was found. in the malt juice, adding 0. 02 % k + or 0. 03 % a13 + can increase the production strikingly and adding some degree concentration trahalose can increase the production too and cut short the time of taming. in the study of using molasses producting ethanol, we can obtain high productivity contained the following composition : nitrogen source 1. 5 % maize and 0. 075 % ( nh4 ) 2so4

    本實驗以常規的育種方法，通過對酵母細胞懸液和原生質體進行一系列誘變，經過大量的篩選，最終選育出一株耐高溫高產菌株75l _ （ 3566 ） ，並對其進行了生產性能的測定。 75l _ （ 3566 ）在40條件下，濃度為20 bx的麥芽汁發酵液中，產酒率高達11 . 5 ，而且發酵速度快，發酵周期可縮短12h ，其生產性能穩定，可以適應大部分以澱粉質為原料的生產廠家的需要。同時本實驗對75l _ （ 3566 ）進行了發酵條件優化的初步研究。
