      Study on selenium enrichment process of Lactobacillus rhamnosus under satt stress. (English)
    • نبذة مختصرة :
      Taking Lactobacillus rhamnosus as the research object? the selenium content and selenium enrichment rate of Lactobacillus rhamnosus were measured by inductively coupled plasma emission spectrometry (ICP-OES). On the basis of single factor experiment，response surface optimization was applied to optimize the process conditions. The optimum process was as follows ： salt concentration 9 %，culture pH 6. 5 and culture temperature 37 曟.The selenium enrichment rate was 65. 35%? which increased by 437. 63 (J-g/g and 14. 7% com­pared with the unstressed group.
