Influence of temperature change on the immobilization of soil Pb and Zn by hydrochar: Roles of soil microbial modulation

Yitong Dan et al.

Summary: A 60-day soil incubation experiment was conducted to study the effect of ambient temperature (5, 25, and 35 degrees C) on the immobilization of Pb and Zn by chitosan-magnetic sawdust hydrochar (CMSH) and magnetic chitosan hydrochar (MCH). The results showed that higher temperature led to decreased DTPA available state content and increased stable state Pb and Zn content. The microbial community analysis revealed that elevated temperature favored metal-stable phyla and inhibited the growth of certain bacterial groups.

Enhancing phytoremediation of soils polluted with heavy metals

Maria Gavrilescu

Summary: Environmental pollution with heavy metals adversely affects soil quality and crop yields. Phytoremediation, using plants as hyperaccumulators, provides an environmentally friendly solution, but it is not without its drawbacks. Plant toxicity and low bioavailability of heavy metals in soil are major challenges. Various techniques have been proposed to enhance and expedite phytoremediation by increasing plant tolerance to heavy metal toxicity and promoting heavy metal extraction and transport.

Review of soil heavy metal pollution in China: Spatial distribution, primary sources, and remediation alternatives

Yufeng Wu et al.

Summary: With the development of economy, soil heavy metal pollution has become more severe, leading to degradation of soil resources and deterioration of ecosystems. This study focuses on the analysis of heavy metal pollution in Guangxi, Fujian, Liaoning, and Yunnan provinces in China. The results show that heavy metal concentrations increase from north to south, with the highest pollution in Northeast China and excessive levels in Central, Southwest, and South China. Mineral exploitation and industrial production are the primary causes in severely polluted provinces, while sewage irrigation and irrational fertilizer use contribute to pollution in agricultural areas. Urban development, transportation, and household refuse are also potential driving factors. Remediation methods involving physical-chemical, chemical-biological, and physical-biological technologies are widely applied, with a focus on combining phytoremediation and microbial remediation techniques for their environmental friendliness. Overall, this study provides valuable information on spatial distribution, sources, and remediation alternatives for soil heavy metal pollution, contributing to the protection of soil resources and land utilization.

The Influence of Iron Application on the Growth and Cadmium Stress Tolerance of Poplar

Mingwan Li et al.

Summary: There is a complex interaction between cadmium (Cd) and iron (Fe) in soil. This study investigated the effects of Fe application on the growth, Cd accumulation, and antioxidant capacity of poplar under Cd exposure. The results showed that high-dose Fe could alleviate the suppression of Cd on poplar growth and enhance Cd transport to aboveground tissues and SOD activity in roots and leaves, thus reducing Cd-induced oxidative stress. This study provides valuable information for the remediation of Cd-contaminated soils using poplar.

Summary: Pathogen suppression and induced systemic resistance are alternative strategies for sustainable agriculture, and Actinobacteria have been widely used as biocontrol agents. Actinobacteria not only produce substances and enzymes that antagonize pests, but also stimulate plant growth. They can also induce systemic resistance against pathogens, but the mechanisms are still unclear.

Two plant growth-promoting bacterial Bacillus strains possess different mechanisms in affecting cadmium uptake and detoxification of Solanum nigrum L.

Yaowei Chi et al.

Summary: Two plant growth-promoting bacteria were found to influence the uptake and detoxification of cadmium in Solanum nigrum by regulating phytohormones secretion, alleviating oxidative stress, and promoting plant growth. One strain significantly increased the absorption and accumulation of cadmium, while the other strain had no significant effect on total cadmium uptake. The expression of antioxidant enzyme genes and heavy metal transport genes were regulated by the bacteria, affecting the detoxification of cadmium in the plants.

All together now: regulation of the iron deficiency response

Nabila Riaz et al.

Summary: Iron is an essential micronutrient for plants and animals, with deficiency leading to anemia in humans. Plants heavily rely on plant-based foods as their primary source of iron, but these foods are often poor sources of dietary iron. Understanding how plants adapt to iron deficiency is crucial for optimizing iron uptake and ensuring optimal plant growth.

Improvement of alfalfa resistance against Cd stress through rhizobia and arbuscular mycorrhiza fungi co-inoculation in Cd-contaminated soil

Xia Wang et al.

Summary: This study showed that co-inoculation of rhizobia and arbuscular mycorrhiza fungi significantly improved alfalfa resistance to Cd stress, with changes in rhizosphere microbial community structure and increased bacterial diversity. The improved resistance was mainly attributed to the enhancement of antioxidant enzyme activities, along with mitigation of Cd-induced lipid peroxidation and reactive oxygen species stress. The enrichment of certain key bacterial taxa induced by co-inoculation enhanced alfalfa' ability to uptake rhizosphere nutrients and reduce carbon release into soil, providing insights into microbe-induced phytomanagement.

Summary: Nitrogen fixing symbiosis between rhizobia and legumes plays a crucial role in providing nitrogen to agricultural and natural environments. Inoculation of symbiotic strains can significantly impact the microbial community in the rhizoplane+endosphere of legume roots, while the rhizospheric soil remains relatively unchanged. The success of an inoculated symbiont depends on its ability to compete with other soil bacteria for colonization of the roots.
