Cdc5 gene is necessary for the g2 / m transition. cells with mutations in cdc5 can not finish the g2 / m transition, then die ; overexpression of cdc5 can shorten g2, the cell cycle as well. it also makes cells lessening
1976年, nurse等在篩選裂殖酵母( s . pombe )細胞周期進程突變體的過程中得到了基因cdc5 ,后來經實驗證明cdc5對細胞周期g2期到m期的轉換是必需的: cdc5突變后造成細胞無法完成g2 m轉換而死亡;過量表達cdc5會縮短g2期,同時縮短整個細胞周期,並導致細胞變小。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。
