Summary: Understanding the ecological roles of phosphate-solubilizing bacteria (PSB) is crucial for optimizing composting systems. A study using sequencing, gene quantitation, and statistical analyses found that the inoculation of PSB significantly increased phosphorus availability and altered bacterial community composition in compost. Different factors, such as phosphorus fractions, PSB abundance, phosphorus-cycling gene abundance, and bacterial community composition, contributed to phosphorus availability in different ways.

Summary: This study investigated the effects of different initial C/P ratios on phosphatase activity, key bacteria, and phosphorus availability in compost. The results showed that adjusting the initial C/P ratio could affect the activity of phosphatase and promote the production of available phosphorus, but it was also inhibited by the feedback of available phosphorus. This study demonstrated the feasibility of adjusting the initial C/P ratio of sludge composting and provided theoretical support for optimizing the application of sludge composting products with different initial C/P ratios.

Summary: In this study, we explored the ecological functions of phoD-harboring bacteria and differences in compost properties among four animal manure groups through small-scale composting and sequencing analysis. The results showed significant compositional differences, complex coexistence patterns, and strong environmental constraints in the phoD-harboring bacteria community of the pig manure group compared to other groups. The temperature-affected phoD-harboring bacterial community directly and indirectly influenced compost phosphorus availability, and the pig manure group had notably higher available phosphorus content in the final compost. These findings have important implications for guiding small-scale manure composting and utilizing compost as biological phosphorus fertilizer.

Summary: The release of dissolved legacy phosphorus from stream sediments is an unquantified vector of non-point nutrient loading in rural Southern Ontario watersheds. This study identified the most vulnerable fractions of phosphorus in sediments from sites of differing agricultural intensity, and revealed that labile and reducible Fe-P can serve as both sinks and sources of phosphorus depending on site conditions. Additionally, high ratios of TDP:SRP indicate that large reservoirs of dissolved P can become immobilized across sites.

Summary: Iron (Fe) speciation in marine sediments and suspended particulate matter (SPM) is commonly used to investigate the role of Fe minerals in marine biogeochemical cycling and to reconstruct paleo-redox conditions. Two commonly used methods for Fe speciation determination are sequential extraction and synchrotron radiation-based X-ray absorption near edge spectroscopy (XANES). This study compared Fe speciation obtained by these two methods and found that they yield comparable results for the approximate proportion of reactive Fe in the total Fe pool and the extent of pyrite formation. However, methodological issues complicate a direct comparison of specific mineral groups. The findings of this study have implications for the transferability of XANES-based Fe speciation to traditional studies on Fe biogeochemical cycling and paleo-redox conditions.

Summary: This paper investigates heavy metal pollution in agricultural fields near the largest landfill in Senegal by comparing total concentrations and speciation of heavy metals. The majority of heavy metals are bound to the residual fraction, making them less likely to be released into the environment. The metal pollution is more severe in certain sampling sites, and the exchangeable fraction in the soil suggests that some elements may be easily released. Some vegetables analyzed had high concentrations of certain heavy metals, but consuming them does not pose significant health risks except for cassava and cassava leaves.

Summary: Diverse phosphorus-containing materials (PCMs) have been widely used in the remediation of cadmium-contaminated soils, and their effects on soil cadmium availability (SCA) vary depending on their physicochemical characteristics and environmental conditions. A meta-analysis of literature published before August 2021 was conducted to investigate the impact of PCMs on SCA reduction under different conditions. The results showed that application rate is the most important factor contributing to SCA, followed by soil pH and duration. Medium P input has the potential to reactivate SCA, while PCM input can better deactivate SCA under alkaline soil conditions and high soil CEC values.

Summary: This study investigated the performance of a novel coagulant-aided biomass filtration for rapid pretreatment of biogas slurry, aiming to prevent severe fouling during subsequent membrane concentration and maximize resource recovery. The results showed that blending potassium aluminum sulfate (PAS) with cornstalk as filtration media increased the removal of suspended solids, organic matter, and nutrients. By using PAS-aided cornstalk filtration, membrane fouling could be significantly reduced, and water flux in the subsequent ultrafiltration process was doubled. Chitosan was also effective in coagulating biogas slurry, but its low dissolution allowed flushing to permeate when mixed with cornstalk, compromising the filtration performance. The spent PAS-aided cornstalk after biogas slurry pretreatment could be transformed into mature compost with high compostability and the ability to retain and remove heavy metals and antibiotics.
