[Research on the catabolism of phosphonic acids: biodegradation of the C-P bond by Pseudomonas aeruginosa].

3-Aminopropylphosphonic acid and 2-(beta-alanyl-amino)-ethylphosphonic acid can be used by Pseudomonas aeruginosa as a phosphorus source. Both compounds undergo a biodegradation through the cleavage of the C--P bond, without any modification upon the amino or amino-groups of the substrates.
