Summary: The cutaneous microbiome plays an important role in skin diseases, such as atopic dermatitis and psoriasis. Recent studies have shown an overlap in the production of ceramide-family lipids, which protect against symptoms. Environmental pollutants can suppress the production of ceramide-family lipids by health-associated skin bacteria, leading to dysbiosis in atopic dermatitis. A bacterium called Roseomonas mucosa has shown therapeutic potential in atopic dermatitis by modulating tumor necrosis factor signaling. It also demonstrates preclinical efficacy in the imiquimod mouse model of psoriasis. Furthermore, there is a strong association between disease rates of psoriasis and environmental factors such as carbon monoxide, nitrogen dioxide, and particulate matter.

Summary: Microorganisms have the ability to thrive in toxic environments by detoxifying xenobiotic compounds and utilizing carbon, phosphorus, sulfur, and nitrogen from available sources. Biotransformation is the most effective and useful metabolic process for degrading xenobiotic compounds. Recent advances in studying microorganisms, their genes, enzymes, and degradation mechanisms have led to the development of cutting-edge approaches to understand degradative processes and modify the core structure of xenobiotics.

Summary: Some pesticides, such as organochlorines, are highly persistent in the environment due to their stable chemical nature. Microbial degradation of these pesticides using enzymes can effectively reduce their toxicity. The biodegradation process can be manipulated through techniques like bioattenuation, bioaugmentation, and biostimulation to enhance degradation efficiency.

Summary: The efficient electrocatalytic degradation of environmental pollutants is achieved by synthesizing diamond fibers (DFs) with a large surface area and high peak current density as the electrode. DFs can effectively degrade organic pollutants in a short period of time due to their unique structure combining boron dopped diamond film and carbon fibers.

Summary: Microplastics (MPs) are pervasive pollutants in the environment, with increasing accumulation in aquatic, marine, and terrestrial ecosystems due to human activities. These MPs, which degrade slowly, pose a threat to biota by increasing the probability of biomagnification of persistent, bioaccumulative, and toxic substances. In order to remediate MP-pollutants, efficient strategies are needed to prevent the leaching of contaminants into water, soil, and eventually into humans. Microorganisms capable of degrading plastic polymers through enzymatic actions have been discovered, and metagenomics is an effective tool for exploring and characterizing these plastic-degrading microbial consortia and enzymes. Combined with metatranscriptomics and metabolomics, metagenomics can identify and select remediation-efficient microbes in their natural habitats. Advances in bioinformatics and sequencing tools enable rapid screening, mining, and prediction of genes involved in polymer degradation. This review provides a comprehensive summary of the growing threat of microplastics globally and emphasizes the role of metagenomics and computational biology in developing effective strategies for MP remediation.

Summary: Sulfonylurea herbicides are widely used in modern agriculture but have adverse effects on ecosystems and human health. Effective techniques, including biodegradation, have been explored to remove sulfonylurea residues from the environment. Microbial strains such as Talaromyces flavus LZM1 and Bacillus subtilis LXL-7 show high degradation capabilities. The molecular mechanisms of microbial degradation are not well studied, but enzymes such as hydrolase, oxidase, dehydrogenase, and esterase play important roles. This article provides a comprehensive discussion on the strains, pathways, and mechanisms of sulfonylurea biodegradation, as well as their toxic effects on aquatic and terrestrial animals, aiming to offer new ideas for remediation of sulfonylurea herbicide-polluted soil and sediments.

Summary: Glyphosate, a broad-spectrum herbicide, is widely distributed and poses a serious threat to human safety and ecology. Microbial degradation has emerged as a promising method for treating glyphosate due to its efficiency and environmental friendliness. Microorganisms can utilize glyphosate as a nutrient source and degrade it into harmless products by cleaving specific bonds. However, the enzymes and functional genes involved in glyphosate degradation and the resistance mechanisms of microorganisms to glyphosate are not well understood.

Summary: The experiment analyzed the impact of different doses of fly ash in soil on the growth performance, phenolics, flavonoids, and elemental uptake of Calendula officinalis. The results showed that low ratios of fly ash amendment to soil improved plant growth, while high fly ash doses tended to decrease growth parameters. A 40% concentration of fly ash did not contain toxic levels of elements and resulted in improved growth and yield. Additionally, increasing fly ash application up to 60% showed an increasing trend in phenolics and flavonoids in leaves.

Summary: This study investigated the impact of FA application on the growth performance and antioxidant defense activity of Calendula officinalis. The results showed that plant growth and metal tolerance increased with low dose FA (40%) amended soil, but decreased with higher FA application. Incorporating 40% FA in soil improved both soil properties and biochemical parameters in Calendula, but high FA applications caused a decline in these parameters. The study also revealed that Calendula exhibited increased antioxidant enzyme activity to combat heavy metal stress from FA. This research highlights the suitability of 40% FA-amended soil for growing Calendula and its potential as a metal tolerant species for phytoremediation of FA-amended soil.

Summary: In this study, a comparative analysis of the genes encoding different intolerant proteins (IP) in bread and durum wheat was performed using a transcriptomics approach. The results showed that bread wheat expressed a greater number of IP genes, most of which were upregulated. These IP genes belonged to thionin, serpin, ATI, gliadin, and glutenin categories. Durum wheat showed a higher amylose:amylopectin ratio compared to bread wheat. These findings support the hypothesis that tetraploid durum wheat is less intolerant and more suitable for consumption by the vulnerable population than hexaploid bread wheat.

Summary: The present study aimed to investigate the variation in the metal(loid)s composition, phytochemicals, enzymatic and nonenzymatic antioxidants activity of pot marigold grown in different treatments of soil and fly ash. The results revealed that a high accumulation of Fe, Cu, Ni, Co, Zn, and Cr with bioaccumulation factor (BAF > 1) was detected at 40% FA treatment. Furthermore, the phenolic and flavonoid content were increased by 35.44 and 160.13% respectively whereas, DPPH and ABTS activity (with low IC50) was decreased by 82.67 and 31.87% in ethanolic leaf extract at 60% FA application compared to the control.

Summary: Fly ash is a solid waste generated from coal combustion in thermal power plants, which is both harmful to the environment and beneficial for agricultural crops. Utilizing fly ash as a soil ameliorant enhances crop productivity by improving soil properties, but heavy metals present in fly ash can pose phytotoxicity to plants and induce oxidative stress. Understanding the antioxidative system of various plant species in response to heavy metal damage is crucial for determining the optimal concentration of fly ash for plant cultivation in agriculture.
