Summary: In this study, a novel bacterial strain, Bacillus altitudinis D47, with a high capacity to biodegrade dinitrotoluene sulfonates (DNTS) was isolated and identified from TNT red water-contaminated soil. The genome of B. altitudinis D47 was sequenced, and six nitroreductases (NRs) were retrieved. Transcriptomic analysis showed that the expression of five NRs was significantly upregulated in DNTS-treated B. altitudinis D47, and enzymatic activity assay validated their nitro reduction capability. The addition of B. altitudinis D47 alleviated the phytotoxicity of DNTS to alfalfa, suggesting its potential application in the bioremediation of TNT red water-contaminated soil.

Summary: The effect of dietary lead on the intestinal microbiome was studied by feeding mice diets amended with lead compounds. Changes in the microbiome, particularly in the cecal microbiomes, were observed in mice fed lead acetate or lead in reference soil. This was accompanied by increased abundance of functional genes associated with metal resistance. Understanding the relationship between microbiome composition, predicted functional genes, and lead concentration is important for selecting optimal treatment methods for contaminated sites.

Summary: This study examined the feasibility of deriving Soil Environment Criteria (SEC) using the bio-accessibility of pollutants. Soil samples from 33 locations at 12 mining/smelting sites in China were collected and analyzed for soil properties, chemical fraction distributions, and bioaccessibilities of cadmium (Cd), lead (Pb), and arsenic (As). The measured and predicted bioaccessibilities of these potentially hazardous trace elements (PHEs) were found to be feasible for deriving SEC. This research will contribute to the development of regional soil environmental standards for mining/smelting soils contaminated with Cd, Pb, and As based on bioaccessibility.

Summary: The study demonstrates the feasibility of using dry thermal techniques to decontaminate soils contaminated with Bacillus anthracis spores. Results showed that increasing temperature and relative humidity reduced the time required to achieve soil samples with no spores detected. The thermal inactivation of spores varied depending on the temperature and humidity conditions, with different depth and soil types impacting the effectiveness of the treatment.

Summary: This study artificially contaminated a pristine soil with 2-chlorodibenzo-p-dioxin (2-CDD) and divided it into three portions. Microcosms SSOC and SSCC were seeded with Bacillus sp. SS2 and a three-member bacterial consortium respectively, showing significant degradation of 2-CDD. The microbial composition complexity in the contaminated soil decreased, with Firmicutes being the dominant phylum.

Summary: House dust and residential soils can be significant sources of lead exposure for children. This study combines X-ray absorption spectroscopic fingerprinting and in vivo mouse relative bioavailability measurements to gain a better understanding of the determinants of house dust lead bioavailability. The results show that highly bioavailable lead species indicative of paint are major components in house dusts, with lead from paint likely driving measured bioavailability.

Summary: The study found that inoculating Bacillus methylotrophicus and adding rhamnolipid can effectively degrade TPH in petroleum-contaminated soil. After remediation, the abundance of indigenous petroleum-degrading bacteria increased significantly, and the interaction among microorganisms can promote non-specific oxidases to remove TPH in soil.

Summary: This study found that using Morchella mycelium to remediate lead-contaminated soil is more efficient than using hyperaccumulating plants. Mycelium can reduce lead content in plants and increase dry biomass, enhance enzyme activities in soil, and reduce the bioavailability of lead. Additionally, mycelium immobilizes lead by forming salt crystals through extracellular secretions, effectively fixing lead in the soil.

Summary: This study identified mercury-resistant bacteria (MRB) isolated from areas impacted by artisanal small-scale gold mining in Bengkulu Province, Indonesia, and analyzed their ability to transform Hg2+ to Hg-0. Two bacterial isolates showed high efficiency in degrading multiple metals, suggesting their potential in bioremediation of mercury and other toxic metals. This study is the first to report the structural and functional diversity of Hg-resistant bacteria in unexplored ASGM-impacted areas, highlighting their biotechnological potential as novel tools for the transformation and adsorption of mercury and other toxic metals.

Summary: This study investigated the impact of plant growth regulators (PGRs) on the production of Miscanthus x giganteus, a second-generation energy crop, on marginal post-military soil. The results showed that Charkor had a positive influence on the development of M. x giganteus, especially in the second year. The effects of Stimpo and Regoplant were less noticeable, but certain combinations of treatments showed satisfactory results. The study also detected the inter-influence of PGRs, soil, and year of growing on the production process.

Summary: The phytoremediation of industrial crops is a popular method for revitalizing land contaminated by trace elements (TEs). This study investigated the influence of plant growth-promoting bacteria (PGPB) on the phytoremediation of an industrial crop, M. x giganteus, in TEs-contaminated soil. Results showed that PGPB had low effects on biomass harvest, but significant effects on the uptake of individual TEs. The study provides insight into the factors influencing phytoremediation supported by PGPB.

Summary: This research investigated the effects of waste-derived Miscanthus biochars on soil properties and Spinacia oleracea L. growth. The results showed that the incorporation of biochar increased soil organic carbon, pH, K, and P2O5 content. However, increasing biochar dose did not necessarily improve yield or photosynthetic parameters. It is recommended to evaluate the effects of biochar on target crop development through preliminary trials before field-scale application.

Summary: Plant growth-promoting bacteria (PGPB) enhance plant growth and protect plants from biotic and abiotic stresses through mechanisms such as colonization of plant surfaces and the formation of protective biofilms. These biofilms offer benefits like resistance to environmental conditions, protection against pathogens, and improved nutrient acquisition, facilitating beneficial bacteria-plant interactions. PGPB biofilms can outcompete other microorganisms on plant surfaces and increase agricultural productivity and crop yields.

Summary: Seed priming methods can improve seed germination and seedling vigor, and also help plants withstand abiotic stress. Among these methods, biopriming stands out as it not only provides the aforementioned benefits but also manages biotic stress. Biopriming using beneficial microorganisms, especially plant growth-promoting bacteria, is an environmentally-friendly alternative to chemical fungicides and has been proven effective in various crops worldwide. In this study, bacterial strains were isolated from different sources and screened based on their solubilization ability of potassium, phosphorus, and production of the plant growth hormone indole acetic acid. The most efficient bacteria were identified and further examined for their additional plant growth-promoting properties. Carrot seed germination assays were conducted with the selected potent isolates, and several isolates showed positive effects on germination. The study emphasizes the role of auxins in seed germination and suggests that phosphate solubilization ability may also play a role.

Summary: The second generation biofuel crop Miscanthus x giganteus (Mxg) was studied as a potential candidate for remediation of petroleum hydro-carbons (PHs) contaminated soil. The study revealed inhibitory effects of diesel contamination on plant parameters, but the impact was lower than expected. Additionally, lower concentrations of PHs actually stimulated electron transport. The research confirmed the potential of Mxg for diesel contaminated soil phytomanagement, particularly in PHs concentrations up to 20 g & BULL;kg 1 where phytoremediation was proven effective.
