摘要
利用啤酒酵母对钒的富集作用制备钒酵母,并对钒酵母中钒的含量进行分析。结果表明,钒酵母中有机钒含量可达到474.9μg/g,紫外扫描光谱分析,钒酵母在311nm处有一特征吸收峰,红外光谱分析,钒酵母有多处特征吸收峰的变化。用氨基酸自动分析仪对钒酵母中的15种氨基酸含量进行分析表明,钒对啤酒酵母氨基酸的合成有一定的影响。
The aim of this study is to prepare the vanadium-rich yeast according to its ability enriching inorganic vanadium and determine the content of the vanadium. The results showed： the content of the organic vanadium was 474.9 μg/g. The absorption peak of vanadium-rich yeast was 311 nm by using ultraviolet and several changes examined by infrared spectrometry. After analyzing of 15 kinds of amino acid, it was found that the vanadium have some influence on amino acid＇s synthesis of yeast.
