Metabolism of phosphonoacetate as the sole carbon and phosphorus source by an environmental bacterial isolate.
A gram-negative bacterium isolated from activated sludge was able to utilize up to 25 mM phosphonoacetate as the sole carbon and phosphorus source, with simultaneous excretion of virtually equimolar levels of phosphate. 2-Aminoethylphosphonate was similarly utilized with equivalent growth rates and cellular yields, while 3-aminopropyl-, 4-aminobutyl-, methyl-, ethyl-, and phenylphosphonates served only as phosphorus sources.
