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.

The hydrogen of the phosphonic acid donated a nonclassic carbon H-bond to Phe182, Cys215, Ser216, Ala217, Gly218, and Arg221.
Mohapatra and coworkers modified the surfaces of magnetite nanoparticles with 2-carboxyethyl phosphonic acid and carboxylic acid [72].
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.
