Analysis of the herbicide glyphosate and related organophosphonates in seawater [PDF]

open access: yes, 2020
Methods for the detection of polar organophosphonates like the herbicide glyphosate and its metabolite aminomethylphosphonic acid (AMPA) in seawater were developed within this thesis. These compounds are difficult to measure in saltwater because salt matrix ions hamper their enrichment and instrumental analysis. Matrix effects were successfully reduced

Organophosphonates revealed: new insights into the microbial metabolism of ancient molecules [PDF]

open access: yesNature Reviews Microbiology, 2013
Organophosphonates are ancient molecules that contain the chemically stable C–P bond, which is considered a relic of the reducing atmosphere on primitive earth.

Pore-Size Tunable Mesoporous Zirconium Organophosphonates with Chiral l-Proline for Enzyme Adsorption [PDF]

open access: yesInorganic Chemistry, 2007
Mesoporous zirconium organciphosphonates with a tunable mesopore (pore diameter: from 4.8 to 16.3 nm) were synthesized through co-condensation of ZrCl4 and 1-phosphomethylproline (H3PMP) with the aid of organic additives in the presence of an anionic ...

Organophosphonate Biofunctionalization of Diamond Electrodes

ACS Applied Materials & Interfaces, 2014
The modification of the diamond surface with organic molecules is a crucial aspect to be considered for any bioapplication of this material. There is great interest in broadening the range of linker molecules that can be covalently bound to the diamond surface.

Utilisation of structurally diverse organophosphonates by Streptomycetes

Applied Microbiology and Biotechnology, 2003
A group of streptomycete strains was found able to utilise a wide range of structurally diverse phosphonates as a sole phosphorus source. No relation could be observed between ability to synthesise compounds containing a direct carbon-to-phosphorus (C-P) bond and biodegradative potential towards phosphonates in the strains studied.

Fluorescent organophosphonates as inhibitors of microbial lipases

Chemistry and Physics of Lipids, 2003
Short- and long-chain 1-O-alkyl-2-acylaminodeoxyglycero- and alkoxy-alkylphosphonic acid p-nitrophenyl esters were synthesized as inhibitors for analytical and mechanistic studies on lipolytic enzymes. The respective compounds contain perylene or nitrobenzoxadiazole as reporter fluorophores covalently bound to the omega-ends of the respective 2 ...

Degradation of organophosphonates by Penicillium citrinum

Letters in Applied Microbiology, 1992
Utilization of organophosphonates as the sole source of phosphorus, carbon or nitrogen by a soil isolate of Penicillium citrinum was studied. Penicillium citrinum was found to utilize 2-aminoethylphosphonic and 2-oxoalkylphosphonic acids as the sole phosphorus source whereas 1-hydroxyalkylphosphonates as well as 1-aminoalkylphosphonates and their ...
