Abstract
A pseudomonad was isolated from the fluoroacetate-producing plant Dichapetalum cymosum (Hook) Engl. and identified as Pseudomonas cepacia. We established that this isolate was capable of growing in fluoroacetate-enriched solutions without any reduction in growth rate. Our isolate of P. cepacia was capable of defluorinating 2.69 mg of fluoroacetate per 10(9) cells per h. Fluoroacetate was degraded to CO2 at a rate of 23.53 ng/10(9) cells per h.
摘要
从产生氟乙酸的植物簇花草（Dichapetalum cymosum (Hook) Engl.）中分离出一株假单胞菌，并鉴定为洋葱伯克霍尔德菌（Pseudomonas cepacia）。我们确定该分离株能够在富含氟乙酸的溶液中生长，且生长速率没有任何降低。我们分离的洋葱伯克霍尔德菌每10⁹个细胞每小时能够使2.69毫克氟乙酸脱氟。氟乙酸以每10⁹个细胞每小时23.53纳克的速率降解为二氧化碳。
