These five isolates were tested against twenty-three available antibiotics from, aminoglycosides, tetracyclines, quinolones, [beta]-lactams, monobactams, sulphonamides, macrolides, cephalosporins,
phosphonic acid and polypeptide classes of antimicrobials, showed increased resistance.
The priority components thus identified and their precursors are monodesmethyl isoproturon (MDIPU) from isoproturon (IPU), aminomethyl
phosphonic acid (AMPA) from glyphosate (GLYP), thifensulfuron acid (TSA) from thifensulfuron methyl (TSM) and N-(1,1-dimethylacetonyl)-3,5-dichlorobenzamide, also known as RH24580, from propyzamide (PROP) (Fig.
[28] intercalated halloysite with phenyl
phosphonic acid, leading to an enhanced fire behavior of PA6/halloysite nanocomposites.
Synthesis and structure-activity relationships of antibacterial phosphonopeptides incorporating (1-aminoethyl)
phosphonic acid and (aminomethyl)
phosphonic acid.

Through phosphorate biochemistry research, Zechel is striving to find ways to mimic the enzymes in bacteria that naturally break down glyphosate, a
phosphonic acid. Understanding the glyphosate-degrading pathway could allow for enhanced bioremediation of glyphosate-contaminated areas, possibly ameliorating the compound's unsavoury reputation.
The herbicide glyphosate, for being a
phosphonic acid, can act in the direct degradation of chlorophyll a, through demetallation, forming complex with the magnesium ion, and in the indirect degradation, through immobilization of magnesium and manganese, necessary for the formation of chlorophyll and photosynthesis, respectively (Bernards et al., 2005).
The results showed traces of sopropyl methyl
phosphonic acid, the metabolite of sarin, a banned nerve agent.
