摘要: 通过培养产朊假丝酵母比较RNA与蛋白含量的变化,评价加入培养基中的T-2毒素与硒的细胞毒性和生理活性.试验表明,5ppm T-2毒素明显抑制产朊假丝酵母的生长,1ppm硒对生长的促进作用显著,且可完全拮抗5ppm T-2毒素的毒性.Abstract: The changes of RNA and protein synthesis by cultures of Candida utilis(Henneb.)L. et Kreger V. R., resulting in the evaluation of the cell toxicities and physiological activities of T-2 toxin and selenium added in the culture were compared. Our experimental findings indicate the striking growing failure in the yeast receiving 5 ppm T-2 toxin, and the growth to be accelerated markedly and the toxicities of 5 ppm T-2 toxin to be antagonized completely in the yeast receiving Ippm selenium.
