Phosphorus applications in agriculture can lead to significant environmental impacts, necessitating a revolution current agricultural practices. This study explores the potential of hydroxyapatite nanoparticles (nHAPs) synthesized from poultry bones as P fertilizers. nHAPs were produced at 300 °C (nHAP300) and 700 (nHAP700), their effectiveness was evaluated. An vitro solubilization test with Pseudomonas alloputida evaluated bacterium's ability solubilize nanoparticles, assessing dissolved organic acids produced. Additionally, soil leaching measured losses bioavailable compared conventional fertilizer, triple superphosphate (TSP). nHAP300 displayed heterogeneous sizes, while nHAP700 approximately 100 nm size, content 8.8% 19.4%, respectively. successfully solubilized both types demonstrating higher solubility than nHAP300. The TSP treatment resulted (6.35 mg) nHAP treatments (nHAP300 0.32 mg; 0.28 mg), indicating for recycling waste. Our findings indicate that are more efficient release but less prone Utilizing these enables phosphorus recovery waste holds sustainable applications.

Optimizing Bioaugmentation for Pharmaceutical Stabilization of Sewage Sludge: A Study on Short-Term Composting Under Real Conditions

Journal of Fungi, Journal Year: 2025, Volume and Issue: 11(1), P. 67 - 67

Published: Jan. 16, 2025

A significant concentration of pharmaceuticals has been detected within composted sewage sludge. Their uncomplete removal and lack monitoring during composting neglects their potentially toxic effects when used as a soil organic amendment. Previously, we successfully implemented bioaugmentation–composting system focused on toxicity pharmaceuticals’ reduction. This method, however, comprised long inoculant-acclimatization period, making it an unprofitable technology. Hence, this work aimed to explore shorter yet effective process by simultaneously implementing the inoculation native microbial consortium fungus Penicillium oxalicum XD 3.1 in piles sludge olive prunings. All were subjected frequent inoculation, windrow turning, physicochemical biological parameters. Additionally, both bioaugmentation stability degradation evaluated through different analysis rates calculations. One hundred days earlier than previous attempts, treatments achieved adequate conditions, maintained core populations while improving degrading diversity, around 70–72% pharmaceutical remotion. Nevertheless, only produced favorable results ideal for amendments (acute microtoxicity phytotoxicity). Thus, but equally stable with P. was here.
