Carbon-phosphorus bond cleavage activity was investigated in cell-free extracts of Enterobacter aerogenes ATCC 15038 (IFO 12010) and Pseudomonas sp. 4ASW, strains known to utilize a range of phosphonates as sole phosphorus source. In vitro phosphonatase activity was detected in extracts of both organisms; however extensive analysis failed to detect any organic product from phosphonates other than phosphonoacetal dehyde. Non-specific liberation of phosphate was observed in Pseudomonas sp. 4ASW, associated with a single fraction of FPLC-purified extract, and is believed to result from the activity of cellular phosphatases.
