Our results are discussed in light of recent data on Pseudomonas aeruginosa amidinohydrolases. In addition, 2-GEPh proved to be a valuable source of phosphorus; the phosphorus group of its higher homologue 3-guanidopropylphosphonic acid was also used, but the linear bacterial growth curve reflected a limited rate of phosphate release.
