A study was conducted to determine whether the supply of inorganic phosphorus in lake water was sufficient for the mineralization of p ‐nitrophenol (PNP) by a Flavobacterium sp. The bacterium grew following its inoculation into sterile lake water amended with only 20 or 200 ng PNP per ml, but depending on when the water sample was taken, either PNP was not mineralized or it was mineralized slowly. PNP at both concentrations was rapidly mineralized if 10 mM P was added. The degradation of 200 ng PNP per ml was most rapid if the lake water was amended with 10 mM P, it proceeded more slowly with 1 mM P and the initiation of mineralization was delayed to equal extents if the sterile water received 0.1 mM, 0.01 mM or no P. The possible significance of these findings to biodegradation in natural waters is discussed.
