发酵速度 meaning in English

fermentation rate
fermenting rate

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
本实验以常规的育种方法，通过对酵母细胞悬液和原生质体进行一系列诱变，经过大量的筛选，最终选育出一株耐高温高产菌株75l _ ( 3566 ) ，并对其进行了生产性能的测定。 75l _ ( 3566 )在40条件下，浓度为20 bx的麦芽汁发酵液中，产酒率高达11 . 5 ，而且发酵速度快，发酵周期可缩短12h ，其生产性能稳定，可以适应大部分以淀粉质为原料的生产厂家的需要。同时本实验对75l _ ( 3566 )进行了发酵条件优化的初步研究。
