“…Thus, CP lyase activity is induced under phosphate starvation, and microorganisms may use phosphonates as an alternative phosphorus source 77–79. This is in accordance with several studies in which it has been shown that glyphosate is utilised as a phosphorus source, but not as a carbon or nitrogen source, and that phosphate affects degradation of glyphosate negatively 70–73, 75, 80, 81. However, recently microorganisms capable of utilising phosphonates,including glyphosate, as a carbon or nitrogen source even in the presence of phosphate have been isolated, and it has been found that cleaving of the CP bond takes place even if phosphate is present 46, 78, 82–84…”

The very wide use of glyphosate to control weeds in agricultural, silvicultural and urban areas throughout the world requires that special attention be paid to its possible transport from terrestrial to aquatic environments. The aim of this review is to present and discuss the state of knowledge on sorption, degradation and leachability of glyphosate in soils. Difficulties of drawing clear and unambiguous conclusions because of strong soil dependency and limited conclusive investigations are pointed out. Nevertheless, the risk of ground and surface water pollution by glyphosate seems limited because of sorption onto variable-charge soil minerals, e.g. aluminium and iron oxides, and because of microbial degradation. Although sorption and degradation are affected by many factors that might be expected to affect glyphosate mobility in soils, glyphosate leaching seems mainly determined by soil structure and rainfall. Limited leaching has been observed in non-structured sandy soils, while subsurface leaching to drainage systems was observed in a structured soil with preferential flow in macropores, but only when high rainfall followed glyphosate application. Glyphosate in drainage water runs into surface waters but not necessarily to groundwater because it may be sorbed and degraded in deeper soil layers before reaching the groundwater. Although the transport of glyphosate from land to water environments seems very limited, knowledge about subsurface leaching and surface runoff of glyphosate as well as the importance of this transport as related to ground and surface water quality is scarce.

“…GLP-1, Geobacillus caldoxylosilyticus T20, and Pseudomonas sp. PG2982 were reported to consume glyphosate as a nutrient for their growth [ 75 , 76 , 77 , 78 , 79 ]. From the list of glyphosate-degrading microbes, including actinomycetes, bacteria, fungi, and microcytes, the bacteria hold the primary position [ 16 , 80 , 81 ].…”

Glyphosate is a non-specific organophosphate pesticide, which finds widespread application in shielding crops against the weeds. Its high solubility in hydrophilic solvents, especially water and high mobility allows the rapid leaching of the glyphosate into the soil leading to contamination of groundwater and accumulation into the plant tissues, therefore intricating the elimination of the herbicides. Despite the widespread application, only a few percentages of the total applied glyphosate serve the actual purpose, dispensing the rest in the environment, thus resulting in reduced crop yields, low quality agricultural products, deteriorating soil fertility, contributing to water pollution, and consequently threatening human and animal life. This review gives an insight into the toxicological effects of the herbicide glyphosate and current approaches to track and identify trace amounts of this agrochemical along with its biodegradability and possible remediating strategies. Efforts have also been made to summarize the biodegradation mechanisms and catabolic enzymes involved in glyphosate metabolism.

“…With respect to the regulation of phosphonate metabolism, it has been demonstrated for a variety of alkylphosphonate-degrading Gram-negative and Gram-positive bacteria that both transport of phosphonates and phosphonatase are inhibited/repressed in the presence of ortho-phosphate (Rosenberg & La Nauze 1967; Daughton et al 1979b;Lerbs et al 1990). Evidence that this pattern of regulation might not hold for all organisms was recently presented by Schowanek & Verstraete (1990b) who found that methylphosphonate was used simultaneously with ortho-phosphate during batch growth of their isolate MMM101a.…”

Microbial degradation of chelating agents used in detergents with special reference to nitrilotriacetic acid (NTA)

The extensive use of phosphate-based detergents and agricultural fertilizers is one of the main causes of the world-wide eutrophication of rivers and lakes. To ameliorate such problems partial or total substitution of phosphates in laundry detergents by synthetic, non-phosphorus containing complexing agents is practiced in several countries. The physiological, biochemical and ecological aspects of the microbial degradation of the complexing agents most frequently used, such as polyphosphates, aminopolycarboxylates (especially of nitrilotriacetic acid), and phosphonates are reviewed.
