Summary: Cow manure has the potential to serve as a sustainable secondary fuel and phosphorus resource, reducing reliance on finite primary resources. However, the compositional challenges of high solids content, lack of soluble phosphorus, fine struvite particles, and high bicarbonate concentrations hinder efficient and sustainable utilization. Addition of calcium can increase methane production and conversion of struvite to calcium phosphate.

Summary: In this study, CaP granules were developed in the UASB reactor during 250 days of operation, leading to high VSS and methane production rates. Microbial community analysis revealed the proliferation of syntrophic bacteria Vittrophtis and diverse H-2-utilizing methanogens, resulting in a hydrogenotrophic dominant pathway in the UASB reactor.

Summary: Bone mineralization is a complex process involving the interplay between organic and inorganic components of bone tissues. This review focuses on the evolution of mineral precursors in the bone mineralization process and highlights the tight control organisms have over each step. The connection between biomineralization and biomaterial design strategies is discussed, along with the detailed implementation of mineral precursor-based biomaterials in various bone graft materials.

Summary: In this study, the recovery of phosphorus from pig manure was achieved by adding calcium during anaerobic treatment. The addition of calcium showed positive effects on treatment stability and efficiency, resulting in increased phosphorus removal and the formation of calcium phosphate granules. This study highlights the potential of calcium addition for enhancing pig manure treatment and enabling efficient phosphorus recovery.

Summary: A new type of bone repair material, gear-shaped granules (G-GRNs), was reported for rapid bone healing, which formed new bone and blood vessels at the rabbit femur defect sites. Compared with conventional carbonate apatite granules, G-GRNs showed advantages in bone percentage and absorption, providing a basis for the design and fabrication of synthetic bone grafts.

Summary: The simple CaP synthesized with cheap raw materials (CaCl2 center dot 2H(2)O and Na2HPO4 center dot 12H(2)O) can effectively enrich multi-phosphopeptides and identify phosphorylation sites, showing good specificity, high sensitivity, and stability. This facilitates the popularization and application of phosphoproteomics research.

Summary: In this study, carbon felt electrodes modified with manganese ore and magnetic ferroferric oxide were compared. The manganese ore-modified electrode showed a maximum voltage 1.7 times higher than the magnetic ferroferric oxide-modified electrode. The start-up time was reduced by 68%. The removal of chemical oxygen demand reached 91.2% and the enrichment in ammonia nitrogen was up to 68.0%.

Summary: Phosphorus recovery from water hyacinth shows potential for alleviating future P supply shortage. Thermal treatment of calcium and P-rich water hyacinth at different temperatures results in the formation of hydroxyapatite and other Ca-rich phases, which can be utilized as fertilizer for slow release of P in aqueous solutions and for soil neutralization to support crop growth.

Summary: This study demonstrated that increasing the pH in anaerobic reactors can promote the nucleation and mineralization of calcium phosphate, facilitating phosphorus removal. The presence of amino acids in wastewater, along with microbial communities including acetogens and methanogens, plays a crucial role in maintaining pH stability and protecting the stability of calcium phosphate minerals.

Summary: This study investigates the effects of natural organic matter (NOM) and hardness on the galvanic corrosion of lead in the presence of dissolved inorganic carbon (DIC) and pH. The results show that Suwannee River NOM significantly increases the release of dissolved lead in water samples, while hardness and DIC have no significant effect on lead release. The study also finds that the pH level plays a role in lead release, with higher pH levels resulting in lower lead release.

Summary: Phosphate removal from wastewater is a pressing issue due to its contribution to water eutrophication. This study explores the use of heat treatment on eggshell and palm fiber mixtures for phosphate removal, with the resulting samples showing improved adsorption performance. The removal process of phosphate is primarily controlled by chemical adsorption, with the formation of apatite through ligand exchange and precipitation mechanisms.

Summary: Cow manure is an important secondary source of phosphorus. In this study, calcium phosphate granulation was achieved during cow manure treatment using an up-flow anaerobic sludge blanket (UASB) reactor and an acidifying continuously stirred tank reactor (CSTR). The efficiency of phosphorus removal reached 83% in the UASB reactor.
