A possibility of microbiological cleaning of water and soil polluted with asymmetric dimethylhydrazine (ADMH), a highly toxic rocket fuel ingredient (RFI), was studied. Several isolates (bacteria, yeast, and micromycetes) capable of utilizing ADMH as the only source of nitrogen, carbon, and energy were isolated from RFI-polluted tundra soil. Acceleration of RFI biodegradation was achieved using a biosorbent that involved cells of the degrader strain immobilized on granulated activated carbon. Biological testing in Escherichia coli and cereals (wheat and barley) demonstrated that biodegradation significantly decreased the integral toxicity of solutions containing ADMH, suggesting its utility for microbiological cleaning of polluted territories.
研究了对被不对称二甲基肼（ADMH）污染的水和土壤进行微生物净化的可能性，ADMH是一种剧毒的火箭燃料成分（RFI）。从受RFI污染的苔原土壤中分离出了几种能够将ADMH作为唯一氮源、碳源和能源利用的分离物（细菌、酵母和微真菌）。使用一种生物吸附剂实现了RFI生物降解的加速，该生物吸附剂包含固定在颗粒活性炭上的降解菌株细胞。在大肠杆菌和谷物（小麦和大麦）中进行的生物测试表明，生物降解显著降低了含有ADMH的溶液的综合毒性，表明其可用于污染区域的微生物净化。
