“…The bacterial extraction was performed using the gram-negative bacterial strain Acidithiobacillus thiooxidans (AT; DSM 9463) provided by Leibniz-Institut DSMZ (Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH). The AT strain was cultivated in a medium consisting of (all reagents of analytical grade, Merck, Germany) 2 g (NH 4 ) 2 SO 4 , 0.25 g MgSO 4 ∙ 7H 2 O, 0.1 g K 2 HPO 4 , 0.1 g KCl, and 1% (w/v) elemental sulfur per 1 dm 3 of ultrapure water (Millipore, Milli-Q), with pH adjusted to 2.5 using 10 M H 2 SO 4 (Potysz et al 2020 ). The biotic experiments were conducted in Erlenmeyer flasks, where portions of SDC were mixed with 50 cm 3 of fresh medium, 2% (w/v) of elemental S, and 2% (v/v) of bacterial inoculum.…”

The enormous amount of spent catalysts generated worldwide may pose a risk to the environment because of their high load of metals, including vanadium. The latter may be mobilized and released to the environment if managed improperly. Moreover, the catalysts could be considered as secondary resources rather than waste. This study aimed at the efficient extraction of vanadium from spent desulfurization catalyst (SDC) from a sulfuric acid production plant. The raw SDC and the post-extraction residues were characterized in terms of their chemical and phase composition. The metal mobility from the materials was examined with both single-step and multi-step extractions. The environmental risk assessment was performed using sequential extraction. The study revealed that both tested methods (citric acid leaching and bioleaching with Acidithiobacillus thiooxidans) enable the extraction of nearly 96% of V from SDC with a simultaneous reduction of metal mobility. However, the bacterial treatment was found more suitable. The leached residue was mostly (> 90%) composed of SiO2, which makes it a potential candidate for application in construction (e.g., concrete mixtures) after additional examinations. The study highlights the need to develop a metal extraction process for SDC in a way that metal-free residue could be a final product.

“…Fungi and actinomycetes, which live in black soil, degrade SOM into inorganic nutrients and organic acids. Microbial activity in complex microbial inoculants promotes and causes soil property changes by forming chelating compounds, mineral acids, secondary minerals, and polymers, releasing anions or cations, and changing pH uctuations (Potysz et al, 2020). Plants absorb inorganic nutrients, whereas mineral particles decompose organic acids.…”

Aim Traditionally, increased crop yield has been supported by applying a large amount of chemical fertilizer. However, using excessive chemical fertilizers on soils diminishes soil fertility and crop yield while contaminating the ecological environment. Method To replace the fertilizer, microbial inoculants, and maize straws were introduced to the soil as environmental fertilizers in this study. During soybean cultivation, their effects on physicochemical properties, enzyme activity, and microbial community structure in the soil were investigated. Compared to fertilization alone, adding microbial inoculants mixed with maize straw (CSF) during soybean cultivation boosted agronomic traits such as soybean fresh weight, plant height, and stem thickness. Result This increased the physicochemical parameters of the soil, such as pH, available Potassium (AP), and water content, affecting the soil bacterial population. Bacteria abundance and diversity significantly increased, with acidobacter, Proteobacteria, Candidatus_ Solibacte, and Sphingomonas dominating. Redundancy analysis revealed that pH and AP were environmental factors that influenced microbial community structure. CSF boosted microbial diversity and community structure while increasing soybean yield from 3.91–5.46%. Conclusion In conclusion, soil improvement using maize straw and composite compound inoculants produced better outcomes. Our findings offer theoretical and experimental references for soil erosion.

“…Numerous studies have con rmed that soil microorganisms are closely related to soil structure, nutrient content, and organic matter, making them important indicators of soil fertility (Chen et al, 2018b). Microbial activities also promote the weathering of black soil and changes in soil properties through the formation of inorganic acids, compounds, polymers and secondary minerals, the release of cations or anions, and changes in pH (Potysz et al, 2020). Therefore, promoting soil weight reduction and e ciency through the use of appropriate organic and inorganic fertilizers not only reduces pollution but also improves soil acidi cation and collapse caused by long-term use of chemical fertilizers, playing a crucial role in maintaining soil fertility and stability in soil ecosystems (Pei-Pei et al, 2018).…”

Applying a large number of chemical fertilizers to the black soil will not only reduce the black soil fertility and crop yield, but also pollution of the soil environment. Through the field experiment of soybean growth, the objective of this study was to investigated the effects of added compound microbial agent on the improvement of black soil and found effective measures for the prevention and control of soil erosion in the black soil region of Northeast China. Through treatment on soybeans, the bacterial community structure in the soil can be influenced, with the most common bacterial phyla being Proteobacteria, Actinobacteria. Soil available phosphorus, available potassium, and ammonium nitrogen show a significant positive correlation with soybean yield, while pH shows a significant negative correlation with soybean yield. This suggests that moderate application of phosphorus and potassium fertilizers can contribute to an increase in soybean yield, while a decrease in soil pH can have a detrimental effect on soybean yield. Additionally, inoculation with rhizobium can impact the diversity of soil microbial communities, with soil pH and organic carbon having the greatest influence on bacterial community structure. In conclusion, the compound microbial inoculum has a good effect on black soil improvement, which can provide some theoretical and experimental reference for black soil erosion control.
