“…These results suggest that the methanolic and aqueous extract of Anogeissus latifolia DC leaves exhibits the anti-inflammatory property in the acute phase of inflammation but the anti-inflammatory activity is more significant in methanolic extract than aqueous extract and the mechanism of action may be associated with inhibition of the some of the inflammatory mediators like histamine, serotonin, bradykinins, and prostaglandins. Glutamic oxaloacetic transaminases (GOT) is a mitochondrial enzyme present in the highest amount in heart muscle, skeletal muscle, liver, brain, and kidney, whereas glutamic pyruvic transaminase (GPT) is a cytosolic enzyme primarily present in the liver [24]. Upon damage to the tissues, an appreciable amount of these enzymes escapes into the bloodstream and this is bringing out a sharp rise in the serum concentration of these enzymes.…”

Objective: To evaluate and compare anti-oxidant and anti-inflammatory activity of methanolic and aqueous extract of Anogeissus latifolia leaves Methods: The in vitro antioxidant activity was investigated using nitric oxide radical inhibition activity assay, hydroxyl radical scavenging activity assay, DPPH free radical scavenging assay, and reducing power assay. The in vitro anti-inflammatory activity was investigated using erythrocyte membrane stabilization, inhibition of protein denaturation, and proteinase inhibitory activity the in vivo anti-inflammatory activity was investigated using carrageenan-induced rat paw edema. The biochemical parameters were evaluated in the blood, which included the determination of serum glutamic oxaloacetic transaminase and serum glutamic pyruvic transaminase values and in the liver, which includes the estimation of lipid peroxidation, reduced glutathione, and superoxide dismutase. Results: The methanolic extract caused a significant dose depended on the reduction of inflammation when compared with the aqueous extract of Anogeissus latifolia. The anti-inflammatory activity of all groups was found to be comparable to the standard indomethacin group. The maximum percent inhibition in paw edema was found in methanolic extract of Anogeisuss latifolia at a dose of 500 mg/kg was 53.33%, with significant anti-inflammatory activity p<0.001. Conclusion: The leaf extract of Anogeissus latifolia possesses anti-oxidant and anti-inflammatory activity. The therapeutic effect of Anogeisuss latifolia extracts will encourage its use in the treatment of inflammation.

Toxic wastes like heavy metals and dyes are released into the environment as a direct result of industrialization and technological progress. The biosorption of contaminants utilizes a variety of biomaterials. Biosorbents can adsorb toxic pollutants on their surface through various mechanisms like complexation, precipitation, etc. The quantity of sorption sites that are accessible on the surface of the biosorbent affects its effectiveness. Biosorption’s low cost, high efficiency, lack of nutrient requirements, and ability to regenerate the biosorbent are its main advantages over other treatment methods. Optimization of environmental conditions like temperature, pH, nutrient availability, and other factors is a prerequisite to achieving optimal biosorbent performance. Recent strategies include nanomaterials, genetic engineering, and biofilm-based remediation for various types of pollutants. The removal of hazardous dyes and heavy metals from wastewater using biosorbents is a strategy that is both efficient and sustainable. This review provides a perspective on the existing literature and brings it up-to-date by including the latest research and findings in the field.

“…Therefore, there is a dire need to adopt certain alternate sustainable, cost-effective, and eco-friendly measures to improve K + concentration in saline-sodic soils (Wang et al, 2020 ). In this regard, rhizosphere engineering through the use of microbes serves as a fundamental constituent of phytoremediation technology (Deb et al, 2020 ). Plant growth-promoting rhizobacteria (PGPR) inhabiting stressful environments retain the potential to minimize stress through the release of primary and secondary metabolites (Egamberdieva et al, 2019 ).…”

Sodium-induced potassium (K+) deficiency is more prevalent in salt-affected soils. Plants experience K+ starvation thus cytosolic K+/Na+ ratio is lowered, which is a prerequisite for their survival. K+ enrichment in crops can be acquired via K-solubilizing bacteria as a sustainable green agriculture approach. This study was conducted to explore potent K-solubilizing bacteria from the rhizosphere of wheat, rice, and native flora grown in salt-affected soils in two distinct regions of Pakistan. The aim of this work was to evaluate the contribution of microbial consortiums to the improvement of K+ assimilation and cytosolic K+/Na+ ratios in rice crops under saline-sodic conditions. Among 250 bacterial isolates, 9 were selected based on their salt (11% NaCl) and alkali (9) tolerance and K-solubilization indices (1.57–5.67). These bacterial strains were characterized for their plant growth-promoting traits and identified based on 16S rRNA gene sequencing. A consortium of five strains, namely, Enterobacter hormaechei, Citrobacter braakii, Pseudomonas putida, Erwinia iniecta, and Pantoea agglomerans, was used as a bio-inoculant to evaluate its role in K+ assimilation, cytosolic K+/Na+ ratio, and subsequent yield enhancement in rice grown under saline-sodic conditions. The impact of applied consortium on rice was assessed under variable salt levels (Control, 40, 80, and 120 mM) in a pot experiment and under natural saline-sodic conditions in the field. Plant agronomical parameters were significantly higher in the bacterial consortium-treated plants, with a concomitant increase in K+-uptake in root and shoot (0.56 and 0.35 mg g−1 dry wt.) of the salt-tolerant rice variety Shaheen. The root K+/Na+ ratio was significantly improved (200% in 40 mM and 126% in 80 mM NaCl) and in the shoot (99% in 40 mM and 131% in 80 mM) too. A similar significant increase was also observed in the salt-susceptible variety Kainat. Moreover, grain yield (30.39 g/1,000 grains wt.) and biomass (8.75 g) of the rice variety Shaheen, grown in field conditions, were also improved. It can be concluded that K-solubilizing bacteria can be used as bio-inoculants, contributing to growth and yield increment via enhanced K-assimilation and cytosolic K+/Na+ ratio in rice crops under salt stress.
