Summary: Secondary mineralization is a promising method for remediating cadmium pollution in sediments. Phosphate can enhance the formation of stable secondary minerals and provide a new direction for Cd immobilization. The established syntrophic system of phosphate solubilizing bacteria (PSB) and dissimilatory iron reducing bacteria (DIRB) is a prospective bioremediation technology for Cd immobilization in sediments.

Summary: This research provides a new remediation system using phosphate solubilizing bacteria (PSBs) and biochar supported nano-hydroxyapatite (nHAP@BC) to enhance the immobilization efficiency of Cd in river sediment. The results show that the highest Cd2+ immobilization efficiency can reach 90% when using PSB cooperated with 5:1 nHAP@BC under certain conditions. XRD and FT-IR characterization results indicate that Cd may exist in the form of Cd-HAP containing CdPO4.

Summary: The study aimed to evaluate the phosphate-solubilizing efficiency of phosphate-solubilizing microorganisms (PSMs) using tricalcium phosphate (TCP) and Eppawala rock phosphate (ERP). A series of identified isolates were compared in phosphate solubilization using TCP and ERP as a P source. Twelve isolates with higher efficiency were selected for biofertilizer production. The pot trial with Capsicum annuum L. showed that the application of native PSMs as biofertilizer effectively increased plant height, leaf length, and width.

Summary: Rock phosphate is a natural source of phosphorus for agriculture, but its slow release can limit short-term availability to crops. P-solubilizing microorganisms were studied for their ability to improve P availability from rock phosphate. Genomic analysis of selected bacteria revealed genes related to P uptake and metabolism, showing potential for use as bioinoculants to improve rock phosphate solubilization and plant growth under field conditions.

Summary: Livestock systems in Colombia rely on forages growing on soils with high phosphorus retention, limiting phosphate fertilizer efficiency. Inoculation of plant growth-promoting bacteria (PGPB) like Rhizobium sp. T88 and Herbaspirillum sp. AP21 can enhance plant growth in P-deficient conditions through mechanisms related to P cycling. These selected strains showed the ability to solubilize and mineralize phosphate, with different genes related to P solubilization and mineralization, offering potential strategies for improving crop productivity.

Summary: In this study, a novel Mg-modified lignin biochar (MB) was prepared to improve the ability of phosphate-solubilizing bacteria (PSB) to dissolve FePO4. The results showed that the system with MB was more effective in increasing FePO4 dissolution and organic acid production. Characterization results revealed the formation of Fe(III)(2)Fe(II)(P2O7)(2) crystals on the surface of MB, which increased the solubility of Fe-P. This study provides a new method for the development of insoluble phosphate solubilization technology.

Summary: In this study, pig manure biochar (PMB) was used to assist phosphorus solubilizing bacteria (PSB) in exploring the mineralization protection and biofeedback mechanism of biochar on PSB under mixed stress of high concentrations of Pb and Cd. The results showed that PMB+PSB had higher removal rates of Pb2+ and Cd2+ compared to PSB alone. The non-bioavailable fraction of Cd2+ and acid-soluble fraction of Pb2+ in PMB+PSB were increased. The pore adsorption and precipitation of biochar reduced the exposure of PSB to Pb/Cd and stimulated the positive feedback effect of PSB.

Summary: Soil microorganisms play a crucial role in maintaining ecological balance, particularly through their involvement in nutrient cycles. Phosphate-solubilizing bacteria (PSB) are of particular importance in the rhizosphere and can be used as biofertilizers in agriculture. This study identified five species of PSB, including Pseudomonas fluorescens, P. putida, P. taiwanensis, Stenotrophomonas maltophilia, and Pantoea agglomerans, through genetic sequencing. The PSB isolates exhibited varying degrees of phosphate solubilization, with P. fluorescens showing the highest solubilization ability. Additionally, all five PSB species were capable of producing the growth-promoting hormone indole acetic acid (IAA), with P. fluorescens producing the highest quantity.

Summary: Traditional wastewater treatment has focused on removing contaminants for sanitation purposes, but the issues of climate change and depletion of natural resources require methods that also convert waste into chemicals and fuels. The synergistic coupling of microalgae and bacteria in biological treatments shows promise in removing various contaminants and generating biofuels. This review examines the use of algae and bacteria in wastewater treatment and valorization, with emphasis on cell-to-cell adhesion, wastewater properties, and techniques for algae harvesting and production of various valuable products such as biodiesel, bioethanol, biohydrogen, exopolysaccarides, biofertilizers, and animal feeds.

Summary: Soil acidification in managed ecosystems, such as agricultural lands, is primarily caused by the release of protons from the transformation reactions of carbon, nitrogen, and sulfur compounds. The use of liming materials can help neutralize these protons, reducing soil acidity and its negative impacts on the soil environment, food security, and human health. Biochar derived from organic residues has been recognized for its potential in addressing acidic soil through its alkaline nature and liming potential, leading to improved soil fertility and productivity.

Summary: Silver is a rare and precious metal found in minerals and released into the environment through weathering and mining activities. It also enters the environment through manufacturing and use of silver compounds. Silver nanoparticles have become a significant source of anthropogenic silver in the environment. Most silver in soil and water is sorbed to particles and precipitated as various compounds. Humans and animals can be exposed to silver through inhalation and consumption of contaminated food and water. Remediation of silver-contaminated soil and water can be achieved through immobilization and mobilization processes. This review provides an overview of the sources, geochemistry, health hazards, remediation practices, and regulatory mandates of silver contamination in complex environmental settings, and discusses knowledge gaps and research priorities.

Summary: The long-term and large-scale mining of rare earth minerals may result in the accumulation of rare earth elements (REEs) in the environment, posing potential health risks to residents. In this study, hair samples from residents of a mining area, a smelting area, and a reference area were collected and analyzed. The findings revealed significantly higher levels of 15 REEs in the hair of residents from the mining and smelting areas compared to the reference area. The study also suggested that age and location were more influential factors than sex in REE accumulation in residents' hair.

Summary: This study investigated the adsorption capacity of different biomass feedstocks for Pb(II) and the effect of magnetic modification on the adsorption capacity. Results showed that rice straw biochar had the highest adsorption capacity due to its rich mineral content and oxygen-containing functional groups. Magnetic modification improved the adsorption capacity of biochar by changing its surface properties. The study suggests that biochar could be a feasible and effective strategy for removing Pb(II) from wastewater.

Summary: The pollution of microplastics (MPs) is a global concern as they are now a significant part of the food chain. This article reviews the current scientific literature on MPs and their impact on various life forms. Negative effects of MPs on humans are primarily attributed to oxidative stress and immune disruption. MPs not only affect the soil's chemical and physical properties, leading to reduced soil health and productivity, but also harm soil microorganisms. MP-induced plant growth reduction occurs through three mechanisms: reduced root and shoot growth, decreased photosynthesis accompanied by increased reactive oxygen species production, and compromised nutrient uptake due to altered root growth. In order to mitigate these negative effects, different MP removal methods are discussed, including coagulation, membrane filtration, biochar, and biological degradation in soil and wastewater effluents. The use of ozone as an ultrafiltration technique shows promise for MP removal. The article concludes with recommendations for future research to further understand the negative effects of MPs on various life forms.
