Abstract:  This paper offered a method to get organic chromium nutrient by cultivating chromium-enriched yeast.It was found that the solution of low consistency promoted the growth of yeast,and with increasing the chromium concentration in culture,the chromium content of chromium-enriched yeast would increase.The solution of chromium-enriched and normal brewer’s yeast was measured by ultraviolet spectrometry with in 200～320nm wavelength range.A characteristic ultraviolet absorption peak appeared at 260nm.The organic chromium was about 97.6% of the total chromium in chromium-enriched yeast.
