摘要

经过筛选,从受到有机卤素化合物污染的土壤样本中分离出了 7 个能够在以全氟羧酸为唯一碳源和能量源的营养培养基中生长的分离菌株。其中最活跃的菌株 MX-3 在含有全氟壬酸、全氟烯酸和全氟辛烷磺酸的培养基上生长时,在 14 天的培养过程中释放的氟离子浓度分别为 10.55、16.44 和 13.09 毫克/升。

ДЕФТОРИРОВАНИЕ МИКРООРГАНИЗМАМИ НОВЫХ ФТОРОРГАНИЧЕСКИХ ПОЛЛЮТАНТОВ
As a result of screening, seven isolates capable of growth in nutrient media with perfluorocarboxylic acids as the sole source of carbon and energy were isolated from soil samples contaminated with organohalogen compounds. The most active strain among them, MX-3, when growing on media with perfluoropelargonic, perfluoroenanthic acids andperfluorooctanesulfonate, releasedfluoride ions to concentrations of 10.55, 16.44 and 13.09 mg/l, respectively, over 14 days of cultivation.
