NOVELTY - Producing (M1) a biogenic formylphosphonic acid (FPA) derivative comprising incubating hydroxymethylphosphonic acid (HMPA) derivative with one or more HMPA degrading microbes under conditions that allowed degradation of HMPA derivative to form a FPA derivative and collecting the FPA derivative, is new.    USE - (M1) is useful for producing biogenic FPA derivative which is subsequently used for producing a glyphosate. (M2) is useful for isolating a pure culture of HMPA degrading bacteria. (M3) is useful for bioremediating waste water or soil contaminated with the HMPA derivative. (M4) is useful for producing an aminophosphonate derivative, preferably a glyphosate derivative, where the condensation product is subsequently converted to form glyphosate derivative by hydrogenation, oxidation, carboxymethylation or their combination. Optionally, (M4) is useful for producing an aminophosphonate derivative such as hydroxyethylaminophosphonic acid or its salt or ester, where the conversion of the condensation product to form hydroxyethylaminophosphonic acid salt or its ester is by hydrogenation and the hydroxyethylaminophosphonic or its salt or ester is converted to glyphosate or its salt or ester by oxidation. Most preferably, (M4) is useful for producing glyphosate, which comprises or consists essentially of condensing biogenic FPA derivative and an nitrogen-containing compound such as glycine or alkanolamine (preferably ethanolamine) to form a condensation product and subsequent conversion of the condensation product to form a glyphosate (all claimed).    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) isolating (M2) a pure culture of hydroxymethylphosphonic acid (HMPA) degrading bacteria involves seeding a reactor with mixed microbial population, maintaining the reactor with HMPA as the sole carbon source in order to select HMPA degrading bacteria, and purifying the HMPA degrading bacteria;    (2) bioremediating (M3) waste water or soil contaminated with HMPA derivative by exposing waste water or soil to one or more HMPA degrading microbes under conditions that allow the degradation of HMPA derivative; and    (3) producing (M4) an aminophosphonate derivative by condensing a biogenic FPA derivative and a nitrogen-containing compound to form a condensation product, and subsequent conversion of the condensation product to form an aminophosphonate derivative.
