| 摘 要： | 黑曲霉可发酵麦麸生产阿拉伯木聚糖酶和阿魏酸酯酶。发酵后的固体残渣质地柔软,比表面积大。为了加强综合利用能力,研究了其对重金属离子汞的清除作用。结果表明,样品颗粒越小,pH越高,越有利于对汞的吸附,最大吸附量为033g/g(麦麸),最小残留率为02%。

| Abstract: | Wheat bran can be fermented by A. niger to produce Arabic xylanase and ferulic acid esterase. The solid fermentation residues are soft and have large specific surfaces. To improve its comprehensive usage, scavenging effect of Hg by those wheat bran fermentation byproduct is studied. It is indicated that the smaller size of the tested smaples and the higher pH, the higher scavenging rate. The maximum absorption amount is 0.33?g/L wheat bran, and the lowest residue rate is 0.2%. |
