Growth of Escherichia coli on some organophosphonic acids

Canadian Journal of Microbiology, 1969
Escherichia coli (ATCC No. 8739) can use a variety of alkyl and aminoalkylphosphonic acids as a source of phosphorus during growth. Chloromethylphosphonate, phenylphosphonate, hydroxymethylphosphonate, and 2-aminoethylphosphonate will act as a source of phosphorus during growth in the absence of inorganic phosphate.

Hydrogen bonding in mixed ligand copper organophosphonates

Chemical Physics Letters, 2003
The hydrogen bond linking phenylphosphonic acid dimers in a copper organophosphonate supramolecular complex is investigated using ab initio and density functional theory calculations. Both one- and two-proton structures were modelled and the calculated binding energy values indicated the one-proton model to be more favourable.

Review: Organophosphonates: occurrence, synthesis and biodegradation by microorganisms

World Journal of Microbiology and Biotechnology, 1998
The organophosphonates are biogenic and xenobiotic compounds characterized by the presence of a stable carbon to phosphorus (C-P) bond. The C-P bond imparts upon these molecules a relative resistance to (bio)degradation and fears have been expressed over their environmental recalcitrance and possible ecotoxicity, as more than 20×103 tonnes of these ...

Bacterial Transformation of Glyphosate and Related Organophosphonates

Amino(poly)phosphonates (A(P)Ps) are widely used in agriculture, industry, and household products for their herbicidal properties. Glyphosate, a non-selective herbicide, and its main metabolite AMPA are the most prominent examples, while others like ATMP and DTPMP are used for their chelating and scale-inhibiting properties in water treatment and ...

Nanoparticle Metal Oxides for Chlorocarbon and Organophosphonate Remediation

2007
The nanotechnology revolution has affected many areas of science, including chemistry and chemical engineering. Although nanotechnology advances in electronics or in the manufacturing of nanomachines are rather recent developments, nanoscale chemical structures are much older.
