Abstract

A strain of the yeast Kluyveromyces fragilis was screened for its ability to utilize a range of synthetic and natural organophosphonate compounds as the sole source of phosphorus, nitrogen or carbon. Only 4-aminobutylphosphonate was utilized as sole nitrogen source with protein yields increasing proportionally with substrate concentrations up to 10 mM. No 4-aminobutylphosphonate metabolizing enzyme activity was detectable in cell-free extracts prepared from K. fragilis pregrown on 2.5 mM 4-aminobutylphosphonate. None of the organophosphonates tested served as a source of carbon or phosphorus for K. fragilis. (C) 2000 Federation of European Microbiological Societies. Published by Elsevier Science B.V.
