Heavy metals are commonly present in polluted soil mining areas. In this study, we investigated 10 sites of farmland the heavy metal tailing dam collapse area (TDCA) with dominant phyla Acidobacteriota, Proteobacteria, Bacteroidetes, and Planctomycetes. The is a composite contamination multiple metals, Cd, Pb Zn being most severely contaminated, levels Hg Cu exceeding screening values at some sites. Shannon, Chao1 ACE indices revealed high microbial diversity but low relative abundance microorganisms TDCA1 TDCA3 results redundancy analysis (RDA) showed that (Max = 4.31 mg/kg) 100 were important factors affecting community TDCA compared to other metals. Correlation communities RB41 (Acidobacteria) was more resistant concentrations Pb, pollution. genera UTCFX1 (Chloroflxi) norank_TRA3-20 had strong tolerance Hg. significantly negatively correlated norank_WD2101_soil_group (P < 0.05). Therefore these can be used as indicators for monitoring potential contamination. predict changes ecosystem maintain its ecological balance health.

Phosphorus solubilizing microorganisms: potential promoters of agricultural and environmental engineering

Frontiers in Bioengineering and Biotechnology, Год журнала: 2023, Номер 11

Опубликована: Май 12, 2023

Phosphate solubilizing microorganisms (PSMs) are known as bacteria or fungi that make insoluble phosphorus in soil available to plants. To date, beneficial microbes, studies on PSMs indicated they have potential applications agriculture, environmental engineering, bioremediation, and biotechnology. Currently high cost competition from local microbe the most important factors hindering commercialization application for instance biofertilizer, conditioner remediation agent, etc. There several technical strategies can be engaged approach solutions of these issues, mass production, advance preparation, genetic On other hand, further needed improve efficiency effectiveness phosphates, promoting plant growth, preferably. Hopefully, going developed into ecofriendly tools sustainable environment protection management future.

Ecological and sustainable implications of phosphorous-solubilizing microorganisms in soil

Deleted Journal, Год журнала: 2024, Номер 6(2)

Опубликована: Янв. 26, 2024

Abstract Phosphorus (P) is a macronutrient that plants need to grow. However, most of the soil’s phosphorus still insoluble, making it difficult for absorb. This creates barrier ecologically responsible farming methods and calls innovative approaches solubilization. Solublizing microorganisms improve availability phosphorous in soil. The term “phosphorus-solubilizing microorganisms” (PSMs) describes various fungi or bacteria divide into more soluble forms. It shows how PSMs interact with their processes solubilize phosphorus. Soil pH, temperature, nutrient are only few parameters affecting its activity. investigated potential increase plant absorption use, thereby boosting agricultural yield usage efficiency. use effects on environment also evaluated. By using PSMs, farmers may less chemical fertilizers contribute runoff eutrophication waterways. Furthermore, soil structure, decrease losses, cycling, all which health long-term viability systems. Phosphorus-solubilizing have enormous promise environmentally land management. Better availability, greater output, pollution, better possible outcomes PSMs. further study required determine best application strategies, formulations, choices Incorporating operations can potentially environmental sustainability resilience. article will explore addressing critical challenges, including erosion, runoff, sustainable practices, resource conservation.

Cupriavidus B-7 immobilized biochar: an effective solution for Cd accumulation alleviation and growth promotion in pakchoi (Brassica Chinensis L.)

Biochar, Год журнала: 2024, Номер 6(1)

Abstract Cd contamination, especially in farmland soil, can pose serious threats to human health as well ecological security. Stabilization is an important strategy for agricultural soil remediation. In this study, a Cd-resistant strain ( Cupriavidus B-7) was isolated and loaded onto cow manure (CDB), rice straw (RSB) pine wood biochar (PB) investigate its effects on stabilization by 60-day pot experiment. Results indicated that the B-7-loaded (labelled CDBB, PBB RSBB) reduced CaCl 2 -extractable 43.06–59.78%, which significantly superior individual applications of B-7 biochar. Likewise, physicochemical properties, urease, catalase phosphatase activities were improved, indicating improved health. Consequently, dry weights pakchoi’s shoot root increased 938.9–1230.9% 149.1–281.2%, respectively, applying RSBB. Meanwhile, accumulation pakchoi shoots decreased 38.06–50.75%. Notably, RSBB exhibited optimal performance growth promotion alleviation. The structural equation model synergistic effect between B-7. Our research provides some new insights into development strategies green sustainable remediation Cd-contaminated soil. Graphical

A critical review of the interactions between rhizosphere and biochar during the remediation of metal(loid) contaminated soils

Biochar, Год журнала: 2023, Номер 5(1)

Abstract Biochar has a large specific surface area, well-developed pore structure, abundant functional groups, and superior nutrient supply capacity, which is widely available environmentally friendly with its advantages in waste resource utilization, heavy metal(loid) remediation, carbon storage. This review focuses on the interactions between biochar (including raw biochar, (modified/ engineered/ designer biochar), composite biochar) rhizosphere during remediation of soil contaminated metal(loid)s (Pb, As, Cd, Hg, Co, Cu, Ni, Zn, Cr, etc.) effects these microbial communities root exudates (enzymes low-molecular-weight organic acids (LMWOAs)). In terms microorganisms, affects composition, diversity, structure through nutrients, provision colonization sites, immobilization metal(loid)s, introduction exogenous microorganisms. With regard to exudates, provides electron transfer support microorganisms regulates secretion enzymes resist oxidative stress stimulated by ameliorates acidification caused LMWOAs, promotes activity enzymes. The roles mechanisms soils are discussed, as well challenges metal(loid)-contaminated soils, issues that need be addressed future research foreseen. Graphical
