Improving sunflower growth and arsenic bioremediation in polluted environments: Insights from ecotoxicology and sustainable mitigation approaches.

The issue of arsenic (As) contamination in the environment has become a critical concern, impacting both human health and ecological equilibrium. Addressing this challenge requires a comprehensive strategy encompassing water treatment technologies, regulatory measures for industrial effluents, and the implementation of sustainable agricultural practices. In this study, diverse strategies were explored to enhance As accumulation in the presence of while safeguarding the host from the toxic effects of arsenate exposure.

and improved antioxidant system of soybean under chromate stress.

Ecologists around the world are giving great attention to the metal pollution of agronomic soil. Recently, several techniques have been employed to remediate heavy metals, but the use of microorganisms is cheap, less time-consuming, and easily available. In the current study, the endophytic strains, Cp1 and Cp2 were isolated from sterilized 1-5 cm long root and leaf segments of using Hagem media.

Phytohormones producing rhizobacteria alleviate heavy metals stress in soybean through multilayered response.

of the current research was to use plant growth promoting rhizobacteria for sequestration and biotransformation of the toxic form of Cr and As into non-toxic form. Remediating these contaminants using microbes is a common technique and rhizo-microbiota not only relieves metal stress but also acts as biofertilizers. Role of plant growth-promoting rhizobacterial (PGPR) strains Acinetobacter beijerinckii (C5) and Raoultella planticola (C9) in counteracting chromium and arsenic stress in soybean seedlings was assessed.

Enhancement of chromate phytoremediation and soil reclamation potential of Brassica campestris L. by Aspergillus niger.

In the past decades, chromium contamination of agricultural land has become an emerging concern. For land reclamation, several strategies including bioremediation have been used. Owing the potential of hyperaccumulators, the current project aims to enhance the phytoremediation potential of Brassica campestris L.

Biological Synthesis of Silver Nanoparticles by (L.) Herit: From Antimicrobial to Biomedical Applications.

The current study sought to synthesize silver nanoparticles (AgNPs) from (L.) leaf and bulb extracts in order to determine their biological significance and use the toxic plants for human health benefits. The formation of silver nanoparticles was detected by a change in color from whitish to brown for bulb-AgNPs and from light green to dark brown for leaf-AgNPs.

Hybridization of green synthesized silver nanoparticles with poly(ethylene glycol) methacrylate and their biomedical applications.

In the present research, a rapid, simple and efficient green method is used for the incorporation of silver nanoparticles (AgNPs) into poly(ethylene glycol) methacrylate (PEGMA) to create biocatalysts with excellent properties for pharmaceutical purpose. In the first phase, capped AgNPs (Ca-AgNPs) were prepared using green synthetic approach and in the second phase capped AgNPs were hybridized with poly(ethylene glycol) methacrylate to form PEGMA-AgNPs. Both the virgin (naked or uncapped) and polymer-capped materials were characterized spectroscopically and their results were compared.

Phytohormones Producing P1 Mitigates Chromate Stress in Sunflower by Provoking Host Antioxidant Response.

Different physical and chemical techniques are used for the decontamination of Cr contaminated sites. The techniques are expensive, laborious, and time-consuming. However, remediation of Cr by microbes is viable, efficient, and cost-effective.

Pseudocitrobacter anthropi reduces heavy metal uptake and improves phytohormones and antioxidant system in Glycine max L.

Heavy metal contamination due to anthropogenic activities is a great threat to modern humanity. A novel and natural technique of bioremediation using microbes for detoxification of heavy metals while improving plants' growth is the call of the day. In this study, exposing soybean plants to different concentrations (i.

Heavy metal tolerant endophytic fungi Aspergillus welwitschiae improves growth, ceasing metal uptake and strengthening antioxidant system in Glycine max L.

In modern agricultural practice, heavy metal (HM) contamination is one of the main abiotic stress threatening sustainable agriculture, crop productivity, and disturb natural soil microbiota. Different reclamation techniques are used to restore the contaminated site; however, they are either costly or unable to remove contaminant when concentration is very low. In such circumstances, bioremediation is used as a novel technique involving microbes for soil restoration.

Comparative assessment of chromate bioremediation potential of Pantoea conspicua and Aspergillus niger.

The recent work aims at the use of Pantoea conspicua (MT5) and Aspergillus niger (CRS3) to assess their bioremediation potential and growth restoration of Helianthus annuus L. under chromate (Cr) stress. The growth of the P.

Activity guided isolation and mechanistic approach towards analgesic potential of Chenopodium mediated through opioidergic pathway.

The current study is focused towards screening for its phytochemicals, phenolic and flavonoid contents of different species of Chenopodium. The plants were also screened for corroborating the traditional use of medicinal plants locally used for pain by determining the extract and their fractions for the in-vivo analgesic activity by using the modern scientific system. Among chloroform fractions, a high level of total phenolic contents was found in chloroform fraction of Chenopodium ambrosioides (ChAm-Chf) with 57.

One of the main problems of the industrialized world is the accumulation of chromium (Cr) in soil, which is a serious threat to the crops. Complete removal of Cr from the contaminated soils poses a great challenge. However, this issue can be minimised by using plant growth promoting microbes as a bioremediation tool.

Home area network for optimizing telehealth services--empirical simulation analysis.

Telehealth applications such as Video-over-IP and remote sensor monitoring are rapidly growing in utilisation and it has now expanded to the patient's homes. These Telehealth applications are, however highly delay sensitive and require high quality (and bandwidth priority) in order to provide satisfactory performances. However, at the patient's home area network (HAN) environment, typically there is no Internet traffic management system which highly affects the quality of these applications.
