A possibility of efficient extraction of 238U, 239Pu and 241Am by microorganisms from solutions with activity 520-3200 Bq/l has been shown on the example of microbial biosorbent (MBS). MBS presents water-resistant granules consisting of living microorganisms and nutrient substances. The ratio MBS:solution being equal to 1:100 and 1:20, microorganisms extracts 98.9 and 99.8% of 238U; 99.1 and 99.8% of 239Pu, 241Am, respectively. The worked out MBC granules may be utilized by burning with the 4-8 decrease of the volume. It is foreseen to use MBS in industrial processes of treatment of liquid radioactive waste (LRW) for uranium and transuranium elements.
以微生物生物吸附剂（MBS）为例，已表明微生物能够有效地从活度为520 - 3200 Bq/l的溶液中提取238U、239Pu和241Am。MBS是由活微生物和营养物质组成的防水颗粒。当MBS与溶液的比例分别为1:100和1:20时，微生物分别提取98.9%和99.8%的238U；99.1%和99.8%的239Pu、241Am。制备出的MBC颗粒可通过燃烧使其体积减少4 - 8倍后再利用。预计在处理液态放射性废物（LRW）中的铀和超铀元素的工业过程中使用MBS。
