鞘铁菌（Siderocopsa）除锰和固定化

Mn￣(2+)-Removal by Immobilized Siderocapsa

在模拟地下水滤池和滤料的条件下，对二种鞘铁菌进行了除锰和固定化实验．结果表明，鞘铁菌有很强的除锰能力，在该菌大量繁殖时除锰率与菌数显示正相关；鞘铁菌菌体及其代谢产物参与形成滤料表面除锰的“活性滤膜”，用戊二醛交联法固定菌体于滤料中，可加速活性滤膜的形成和提高除锰率；在活性滤膜中还存在着非生物的除锰．

Two species of Siderocapsa were immobilized.The Mn2+removal activity of the immobilized bacteria was measured using artifitial groundwater.It is shown that the increase of the activity iscorrespondent to the multiplication of the bacteria.The cells and the metabolic products of the bacteria participate in the formation of the active membrane filter.Bacteria,when cross-linked on the filtersupport by glutaraldehyde,can promote the maturation of the active membrane filter.Furthermore,non-biological factors can also be observed.
