Abstract
We studied the biodegradation of compounds containing phosphorus-to-carbon bonds by using a wild-type strain of Penicillium notatum. The substrate specificity of this strain was studied, and we found that it is able to utilize structurally diverse organophosphonates as sole sources of phosphorus. This ability seems to be inducible, as indicated by the presence of a lag phase during growth. A popular herbicide, glyphosate, inhibited fungal growth, but it was also degraded by the fungus if it was applied in sublethal doses. This indicates that P. notatum may play an important role in biodegradation of organophosphonates. The strain which we used did not metabolize any of the phosphonates which we tested when they were used as sole carbon or nitrogen sources.

Abstract
Among a collection of 18 fungal strains representing eight genera, only two strains (Penicillium oxalicum and P. minioluteum) were capable of growth on phosphonoacetic acid as sole phosphorous source. Enrichment liquid cultures in minimal medium with the compound as the only P-source selected four isolates, that were also identified as Penicillium spp. Phosphonoacetate metabolism did not lead to extracellular release of inorganic phosphate. In all cases phosphonoacetate hydrolase activity was detected in partially purified extracts, and a protein of the expected molecular mass reacted with polyclonal antibodies raised against the enzyme from P. oxalicum. There was no relation between phosphonoacetate hydrolase specific activity and growth rate or yield. Phosphonoacetic acid was the inducer of the hydrolase, independently of the concurrent availability of inorganic phosphate. Notwithstanding this, the utilization of the phosphonate was significantly inhibited in the presence of phosphate, suggesting an interference of the latter with phosphonoacetic acid uptake.

Abstract
The enzyme responsible for the hydrolysis of phosphonoacetic acid, a non-biogenic C-P compound, was purified to electrophoretic homogeneity from a wild-type strain of Penicillium oxalicum. A 50-fold enrichment was obtained by a combination of anion exchange, hydrophobic interaction and MonoQ-fast protein liquid chromatography, with a yield of one-third of the initial activity. A characterization of the protein showed both similarities and differences with respect to the well-characterized bacterial counterpart. The fungal phosphonoacetate hydrolase is a 43-kDa monomeric protein showing low affinity toward its substrate and high sensitivity to even mildly acidic pH values. Enzyme activity neither required nor was stimulated by the presence of divalent cations. Polyclonal antibodies were raised in mouse against the purified protein, allowing the study of enzyme induction as a function of the phosphate status of the cell. Peptide mass mapping led to the determination of about 20% of the primary structure. Despite the biochemical differences, amino acid alignment showed a high degree of similarity of the fungal hydrolase with the few sequences available to date for the bacterial enzyme. The possible physiological role of a phosphonoacetate hydrolase is discussed.

Abstract
A series of aminomethylene-bisphosphonic acid derivatives, previously synthesized and shown to be endowed with herbicidal properties, were evaluated as potential inhibitors of plant glutamine synthetase. The cytosolic form of the enzyme was partially purified from rice cultured cells and assayed in the presence of millimolar concentrations of the compounds by means of three different assay methods, respectively measuring the hemibiosynthetic, the transferase, and the full biosynthetic reactions. Several compounds were found to exert a remarkable inhibition, with I(50) values similar to those obtained under the same conditions with a well-established inhibitor of glutamine synthetase, the herbicide phosphinothricin. Contrary to the reference compound, enzyme kinetics accounted for a reversible inhibition mechanism. The biological activity of the most active derivatives was further characterized by measuring free glutamine levels in cell suspension rice cultures following treatment with the inhibitors. Results confirmed their ability to interfere in vivo with nitrogen metabolism. A preliminary analysis of structure-activity relationship allowed it to be hypothesized that steric rather than electronic factors are responsible for the inhibitory potential of these compounds.

Abstract
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. Streptomyces morookaensis DSM 40565 could degrade 2-amino-4-phosphonobutyrate as a sole nitrogen and phosphorus source in a stereoselective-like manner. This result suggests the existence of a new metabolic pathway for C-P bond breakage.

Abstract
Aminophosphonic acids were almost unknown in 1959 but today they are the subject of more than 6000 papers. Their negligible mammalian toxicity, and the fact that they very efficiently mimic aminocarboxylic acids makes them extremely important antimetabolites, which compete with their carboxylic counterparts for the active sites of enzymes and other cell receptors. Although biological importance of these compounds was recognized over 50 years ago they still represent promising and somewhat undiscovered class of potential drugs.

Abstract
A Penicillium chrysogenum strain was isolated for its ability to grow in minimal medium containing the herbicide glyphosate as the only nitrogen source. The presence of concentrations up to 25 mM progressively stimulated the fungal growth rate, which was negligible in media lacking reduced nitrogen. However, glyphosate utilization never exceeded 1 mmol g-1 mycelial dry mass, and below a threshold concentration both herbicide uptake and fungal growth were subject to a lag phase, suggesting that the herbicide may enter the cell by either simple passive diffusion or inducible carriers. Amino acids, possible products of glyphosate breakdown, as well as ammonia, were found to replace the herbicide in restoring mycelial growth. Cells were devoid of detectable nitrate reductase activity, thus the isolate seems to be impaired in its ability to convert nitrate to ammonium. In vitro activity of 5-enol-pyruvyl-shikimate-3-phosphate synthase, the target site of glyphosate action, was highly sensitive to the herbicide. Fungal growth rate was considerably lower when the herbicide was also the only phosphorus source, whereas glyphosate utilization was substantially unaffected, suggesting an unusual route for its degradation. Herbicide metabolism was strongly reduced when other sources of organic nitrogen were made available.

Abstract
The effect of N-2-(6-methyl-pyridyl)-aminomethylene bisphosphonic acid (M-pyr-AMBPA), a compound previously shown to exhibit herbicidal properties on whole plants and to inhibit in vitro activity of the first enzyme in the shikimate pathway, 3-deoxy-d-arabino-heptulosonate-7-phosphate (DAHP) synthase, was investigated on Nicotiana plumbaginifolia suspension cultured cells and compared to that of the herbicide glyphosate. The addition of M-pyr-AMBPA from 10(-4) to 10(-3) M was found to cause a severe cell growth reduction. Kinetic analysis of partially purified DAHP synthase accounted for non-competitive inhibition type with respect to both phospho-enol-pyruvate and erythrose-4-phosphate, with K(I) values of 0.43 and 0.62 mM, respectively. Amino acid pool measurements of cells grown in the presence of sublethal doses of M-pyr-AMBPA pointed to an actual reduction of free aromatic amino acids, showing that DAHP synthase inhibition takes place in vivo, and suggesting that the interference of this aminophosphonate with plant aromatic biosynthesis may account for a large part of its phytotoxicity. However, exogenous supply of a mixture of phenylalanine, tyrosine and tryptophan failed to achieve full reversal of cell growth inhibition, yet the occurrence of other target(s) cannot be ruled out.

Abstract
Wild-type Streptomyces sp. strains, able to utilise both naturally occurring and synthetic organophosphonates, were isolated. High levels of inorganic phosphate were necessary for their growth in complete medium as well as in medium, supplemented with phosphonates as the sole carbon or nitrogen source. Isolate StA expressed detectable enzymatic activity against 2-aminoethylphosphonate in vivo. Streptomycete StC had a surprising ability to degrade N-phosphonomethylglycine (glyphosate) in a phosphate-independent manner via C-P bond cleavage accompanied by sarcosine formation.

Abstract
The ability of a wide variety of soil-borne fungal strains to degrade four structurally different compounds containing P-C bonds, namely the naturally occurring amino acid ciliatine, the popular herbicide glyphosate, phosphonoacetic acid and 2-amino-3-phosphonopropionic acid, was studied in order to show that soil fungi may play an important role in the biodegradation of organophosphonates. Most of the strains appeared to utilize ciliatine as the sole source of phosphorus for growth. Only a limited number of strains were able to grow on the other phosphonates used in this work. The strains of Trichoderma harzianum, Scopulariopsis sp. and Aspergillus niger chosen for more detailed study show the ability to degrade ciliatine, glyphosate and also amino(3-methoxyphenyl)methylphosphonic acid effectively.
