“…The Pst protein complex comprises four subunits, an ATP-binding protein (pstB), two transmembrane proteins (pstA and pstC), and a periplasmic PBP (pstS) (Luecke and Quiocho, 1990; Santos-Beneit et al., 2008). The periplasmic pstS PBP has recently attracted interest as a potential high-affinity, phosphate-specific P i adsorbent (Kuroda et al., 2000; Li et al., 2009; Yang et al., 2016, 2017).…”

Progress towards a more circular phosphorus economy necessitates development of innovative water treatment systems which can reversibly remove inorganic phosphate (P i ) to ultra-low levels (<100 μg L −1 ), and subsequently recover the P i for reuse. In this study, a novel approach using the high-affinity E. coli phosphate binding protein (PBP) as a reusable P i bio-adsorbent was investigated. PBP was expressed, extracted, purified and immobilized on NHS-activated Sepharose beads. The resultant PBP beads were saturated with P i and exposed to varying pH (pH 4.7 to 12.5) and temperatures (25–45 °C) to induce P i release. Increase in temperature from 25 to 45 °C and pH conditions between 4.7 and 8.5 released less than 20% of adsorbed P i . However, 62% and 86% of the adsorbed P i was released at pH 11.4 and 12.5, respectively. Kinetic experiments showed that P i desorption occurred nearly instantaneously (<5 min), regardless of pH conditions, which is advantageous for P i recovery. Additionally, no loss in P i adsorption or desorption capacity was observed when the PBP beads were exposed to 10 repeated cycles of adsorption/desorption using neutral and high pH (≥12.5) washes, respectively. The highest average P i adsorption using the PBP beads was 83 ± 5%, with 89 ± 4.1% average desorption using pH 12.5 washes over 10 wash cycles at room temperature. Thermal shift assay of the PBP showed that the protein was structurally stable after 10 cycles, with statistically similar melting temperatures between pH 4 and 12.5. These results indicate that immobilized high-affinity PBP has the potential to be an effective and reversible bio-adsorbent suitable for P i recovery from water/wastewater.

“…Agricultural runoff is defined as P leaching from farmlands through extensive fertilizer application [4], where the P concentration of 0.0001 g L –1 is considered high enough to cause eutrophication [30]. P loss in agricultural run‐off is estimated to be around 8 Mt a –1 worldwide [31]. It causes eutrophication of water bodies evident in toxic algae growth [2,32] up until to the development of death zones in lakes and oceans due to low or no oxygen availability [33].…”

Phosphorus (P) is a non‐renewable resource and is on the European Union's list of critical raw materials. It is predicted that the P consumption peak will occur in the next 10 to 20 years. Therefore, there is an urgent need to find accessible sources in the immediate environment, such as soil, and to use alternative resources of P such as waste streams. While enormous progress has been made in chemical P recovery technologies, most biological technologies for P recovery are still in the developmental stage and are not reaching industrial application. Nevertheless, biological P recovery could offer good solutions as these technologies can return P to the human P cycle in an environmentally friendly way. This mini‐review provides an overview of the latest approaches to make P available in soil and to recover P from plant residues, animal and human waste streams by exploiting the universal trait of P accumulation and P turnover in microorganisms and plants.

“…Algae (e.g. Chlorella ) , mussels ( Mytilus edulis ) and floating aquatic macrophytes like aquatic ferns ( Azolla spp. ) take up P (and N) during their growth and can then directly be either applied to fields or used for other applications like biogas production coupled with secondary P recovery.…”

“…The capacity of active P accumulation and storage as polyphosphates is a feature of many microorganisms. Usually, P is accumulated and stored under aerobic conditions and degraded and released as ortho ‐phosphate under anaerobic conditions to gain energy . The resulting process of enhanced biological P removal has been used in WWTPs worldwide since 1974 , with 15 to 23% of the WWTPs using mostly biological P removal and even more plants (21–36%) using biological P removal with chemical backup (data from Germany, United Kingdom and France) .…”

This Mini Review gives an overview of and respective references for the current situation regarding global phosphorus reserves and the legal situation for P recovery using Germany as the model. Apart from the well‐known pilot up to industrial/full scale recovery techniques, emerging chemical and bio‐based P recovery techniques are named without claiming to be all‐encompassing. Special attention is paid to the biological systems for P recovery that reveal ways for use of renewable resources as raw materials. A few chemically based recovery techniques like AirPrex®, (Ostara)PEARL™, AshDec®, and RecoPhos® have already been used to recover P at a rate and quality which allows for its sale as a fertilizer. Many chemically based processes are at the stage of investigation on a pilot or laboratory scale, e.g. P‐RoC, LeachPhos, and Mephrec®. All of the biologically based technologies like P‐Bac are still at an early stage of research and show promising results. Of all recovered materials struvite, calcium phosphate and biological bound phosphorous seem to have the best plant availability. Although there is no ultimate “one fits all” technology, potential P‐recovery plant operators can choose from a wide range of techniques which will best fit local raw material availability, economic and ecological situation.
