摘要
研究了富铬酵母的培养方法，发现培养基中低浓度的铬（<100mg/kg）对酵母生长起促进作用，且随着铬浓度的增加酵母对铬的富集作用亦增加。用200～320nm波长范围对富铬酵母及普通酵母溶液进行紫外扫描，发现在260nm处有一特征的吸收峰。富铬酵母中有机铬占总铬量的97.6%.
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.
