Abstract

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 phosphonoacetaldehyde. 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.
