Combined Impact of Canada Goldenrod Invasion and Soil Microplastic Contamination on Seed Germination and Root Development of Wheat: Evaluating the Legacy of Toxicity

Plants, Год журнала: 2025, Номер 14(2), С. 181 - 181

Опубликована: Янв. 10, 2025

The concurrent environmental challenges of invasive species and soil microplastic contamination increasingly affect agricultural ecosystems, yet their combined effects remain underexplored. This study investigates the interactive impact legacy Canada goldenrod (Solidago canadensis L.) invasion on wheat (Triticum aestivum seed germination root development. We measured growth parameters by utilizing a controlled potted experiment with four treatments (control, S. legacy, microplastics, treatment). results revealed that affected germination. different seedling properties generally followed an “individual treatment enhances, suppresses” pattern, except for biomass. Specifically, individual promoted However, significantly suppressed development, decreasing total length surface area 23.85% 31.86%, respectively. These findings demonstrate while may promote are detrimental, indicating complex interaction between these two stressors. highlights need integrated management strategies to mitigate impacts crop productivity ecosystem health.

Strategies for cost-optimized biocement production: a comprehensive review

World Journal of Microbiology and Biotechnology, Год журнала: 2025, Номер 41(2)

Опубликована: Фев. 1, 2025

Biocement is a promising alternative to conventional cement, offering advantages in sustainability and reducing carbon footprints. However, its widespread adoption has been hindered by the relatively high production costs. This review aims explore various strategies advancements biocement that can contribute cost reduction. Specifically, we discuss selection of low-cost microbial growth media for microbially induced carbonate precipitation (MICP), utilization plant extractives as enzyme substitutes enzyme-induced (EICP), substitution urea with urine source nitrogen, exploration affordable alternatives calcium ions, valorization ammonia/ammonium byproducts, other pathways. The these could significantly enhance biocement's scalability sustainability, paving way more eco-friendly cost-effective construction practices.

Effect and comparative analysis of urease inhibitor AHA and low pH method on MICP reinforcement of calcareous sand

Frontiers in Microbiology, Год журнала: 2025, Номер 16

Опубликована: Март 27, 2025

In order to alleviate the problem of grouting blockage caused by immediate action bacteria and chemical reagents in process MICP reinforcement sandy soil, this paper delays generation rate calcium carbonate adding urease inhibitor AHA cementing solution lowering pH bacterial solution. The mechanism two methods was explored, their effects were compared analyzed. results indicate that both method low can effectively delay improve effect under different mechanisms action. is best when content 0.1% or drops 5.5. Comparing methods, it found solidification on soil slightly higher than method. This because crystal size generated smaller Under similar content, size, more bonding points between its strength. Exploring urea hydrolysis catalyzed urease. acts binding ions after hydrolysis, as well inhibiting activity. have action, but achieve goal delaying formation.
