“…The C-P lyase ( phnGHIJLKM ) breaks the C-P bond within a wide array of phosphonate substrates resulting in a hydrocarbon and inorganic phosphate [74]. The inorganic phosphate may be used within the bacterial cell or released aiding in accretion through increased ion concentration [75]. However, phosphonates within an environment can prevent precipitation of calcite by binding to crystal growth sites [76] and the degradation of these compounds within the stromatolite formations may prevent chemical inhibition of stromatolite growth.…”

13Stromatolites are complex microbial mats that form lithified layers and ancient forms are 14 the oldest evidence of life on earth, dating back over 3.4 billion years. Their emergence 15 aligns with the oxygenation of the Earth's atmosphere and insight into these ancient 16 structures would shed light on the earliest days of Earth. Modern stromatolites are 17 relatively rare but may provide clues about the function and evolution of their ancient 18 counterparts. Previous studies have assessed microbial diversity and overall functional 19 potential but not at a genome-resolved level. In this study, we focus on peritidal 20 stromatolites occurring at Cape Recife and Schoenmakerskop on the southeastern 21 South African coastline. We identify functional gene sets in bacterial species conserved 22 across two geographically distinct stromatolite formations and show that these bacteria 23 may promote carbonate precipitation through the reduction of sulfur and nitrogenous 24 compounds and produce calcium ions that are predicted to play an important role in 25 promoting lithified mats. We propose that abundance of extracellular alkaline 26 phosphatases, in combination with the absence of transport regulatory enzymes, may 27 lead to the precipitation of phosphatic deposits within these stromatolites. We conclude 28 that the cumulative effect of several conserved bacterial species drives accretion in 29 these two stromatolite formations. 30 31 3

“…Indications for the lower elimination of PBTC, as compared to polyphosphonates, have already been derived from laboratory tests investigating the adsorption of phosphonates on activated sludge. Reichert [7] and Metzner and Nägerl [34] determined maximum PBTC adsorption rates of 50%, while aminophosphonates were found to adsorb to a higher extent [35]. In laboratory tests, PBTC even showed a slight tendency towards desorption (about 30%) from digested sludge under anaerobic conditions [7], implying a possible accumulation of PBTC in the WWTP.…”

Ten times at intervals of 1–2 months, individual treatment stages of two wastewater treatment plants (WWTPs) were analyzed for the five quantitatively most widely used phosphonates. The total dissolved concentration of the investigated phosphonates in the influents was between 131 µg/L and 384 µg/L. The nitrogen-free phosphonates 2-phosphonobutane-1,2,4-tricarboxylic acid (PBTC) and 1-hydroxyethylidene(1,1-diphosphonic acid) (HEDP) accounted for an average proportion of 83–85%. Diethylenetriaminepenta(methylene phosphonic acid) (DTPMP) contributed with 13–14%, whereas aminotris(methylphosphonic acid) (ATMP) (≤15 µg/L) and ethylenediaminetetra(methylene phosphonic acid) (EDTMP) (≤11 µg/L) contents detected in the WWTP influents were comparatively low. The application of new analytical methods allowed the quantification of phosphonates in the solid fraction of the WWTP influents for the first time. High loads of phosphonates were determined (223–2555 mg/kg), indicating that 20%–80% of the phosphonates are present in the adsorbed state. The removal of total dissolved phosphonate by secondary clarification was between 69.7% and 92.4% (medians: 90.7% and 87.7%). In both WWTPs, HEDP (medians: 89.2% and 86.4%) was slightly better eliminated than PBTC (medians: 87.2% and 82.5%). In the sand filtration stage of a WWTP, the average removal was not further improved. In contrast, an additional removal of dissolved phosphonates could be achieved by activated carbon treatment (median: 96.4%). The proportion of phosphonate-P in the dissolved unreactive phosphorus fraction was consistently between 10% and 40% throughout all treatment stages.

“…In contrast to the depletion of phosphate deposits, several anthropogenic activities that release P have caused problems to the aquatic environment, and water quality degradation places water security at risk. Eutrophication, one of the most prevalent water quality problems in the world, is mainly caused by an excess of P. This problem leads to environmental, social, and economic losses (Mozeto et al 2012;Koreivienė et al 2014;Mozeto et al 2014;Pang et al 2017;Papiol 2017;Sinha et al 2017;Anttila et al 2018;Bender et al 2018;Rott et al 2018;Yang et al 2018;Wu et al 2019).…”

A wide range of anthropogenic activities have caused various problems to the aquatic environment, leading to economic, social, and environmental losses. The use of materials for the recovery of water quality is very important due to the water scarcity scenario present in different parts of the world. The use of sawdust as an organic adsorbent for P removal in eutrophic environments attempts to address both water quality preservation and possible application of the organic adsorbent as fertilizer for agricultural practices. This use will result in important contributions to the water and food security. In this work, we performed laboratory experiments to study P adsorption and to evaluate possible adsorption of metals and emerging contaminants by sawdust. The experiments were carried out in 36 microcosms (glass jars), using 50% of the flasks as treatments (containing bags with sawdust) and the rest of the flasks as control (water and sediment without sawdust). For future application of sawdust as a fertilizer it is important to be aware of the presence of possible pathogenic microorganisms, thus the presence of helminth eggs was determined in the sawdust. The results showed the tendency of P adsorption by the biosorbent; maximum adsorption occurred at 214 d (41 μg P g–1), after the P desorption occurred. No helminth eggs or emerging contaminants and toxic metal were detected in the sawdust after its use as biosorbent, providing an important subsidy regarding the use of the biosorbent as soil fertilizer.
