Summary: This study evaluated the effectiveness of adding phosphate, lime, biochar, and biosolids to contaminated forest soil near an abandoned mine site in Brazil for immobilizing potential toxic elements (PTE). The results showed that phosphate decreased Pb desorption but increased Zn desorption; biochar and biosolids immobilized high amounts of Zn and Pb, but a high dose of biosolids increased Pb desorption. Field trials are needed to confirm the long-term immobilization efficiency of lime and other amendments.

Summary: Petroleum hydrocarbons are recognized as priority pollutants in the environment. This study aimed to develop methods for remediation of oil-contaminated soil using new generation sorbents based on organomineral biofertilizer and activated aluminum alloys. The efficiency of cleaning oil-contaminated soils with organomineral sorbents was evaluated, and reduction of oil concentration in soil samples was observed. Additionally, the impact of oil pollution on legume plants and the effects of the sorbents on plant growth were studied.

Summary: In this study, a combined experimental and DFT investigation was performed to study the UV-Vis spectra of o-methoxyaniline-terminated mono azo dyes. The excitation processes were determined using time-dependent DFT calculations and visualized through hole-electron analysis. Fragment-divided analysis was conducted to understand the contributions of different parts of the structures to the spectra. The effect of substituent electronegativity on electron densities and spectra was also investigated. Additionally, a linear model connecting the lambda(max) and W-1/2 to chemical shifts obtained from NMR spectroscopy was developed for the construction of a spectral library.

Summary: The study investigated the effect of successive application of cattle dung and/or dung beetle on the diversity and ecological guild of topsoil fungal assemblages. The results showed that the application of cattle dung significantly improved fungal diversity and ecological guild. However, the addition of dung beetle along with dung may lead to vertical displacement of organic matter and ecologically relevant fungal species to deeper soil depths.

Summary: The study investigated soil fungal diversity and community composition under long-term Cu contamination, revealing a significant positive correlation between soil fungal diversity and plant dry weight. Soil Cu concentration and shoot dry weight were found to be the strongest driving factors influencing fungal composition. Specific tolerant taxa under different Cu contamination gradients were illustrated by the study.

Summary: The study aimed to degrade total petroleum hydrocarbons (TPHs) from contaminated soil using batch microcosm reactors. Soil fungi isolated from the same polluted soil and ligninolytic fungal strains were applied in the treatment of soil-contaminated microcosms under aerobic conditions. Different fungal strains were used for bioaugmentation in mono or co-cultures. The results showed that six fungal isolates exhibited petroleum-degrading potential, with Paecilomyces formosus showing the highest TPH degradation rate of 97%.

Summary: In recent years, chromium contamination in agricultural land has become a growing concern, and various strategies have been used to remediate the damage caused. This study aimed to enhance the phytoremediation potential of Brassica campestris L. by applying a chromate tolerant endophytic fungus, Aspergillus niger CSR3. The results showed that the presence of the endophytic fungus stimulated the growth of B. campestris and increased its ability to accumulate chromate. Additionally, the plants associated with the endophyte had a stronger antioxidant system to cope with the chromate stress. These findings suggest that using hyperaccumulator plants and heavy metal tolerant endophytic fungi can be an efficient way to reclaim contaminated sites.

Summary: The aim of this research was to utilize plant growth promoting rhizobacteria for the sequestration and biotransformation of toxic forms of chromium and arsenic into non-toxic forms. The study found that the isolated rhizobacteria strains were able to tolerate high levels of chromate and arsenate, and convert them into least toxic forms. Additionally, they released stress-related metabolites and plant hormones, benefiting the soybean seedlings.

Summary: Green synthesis of silver nanoparticles (AgNPs) using Tribulus terrestris seed extract as the reducing and stabilizing agent was investigated for its anti-diabetic properties. The synthesized TT-AgNPs were characterized using FTIR, XRD, SEM, and UV-Vis spectroscopy. The spectroscopic analysis confirmed the development of TT-AgNPs, and SEM revealed their loose clustering and spherical structure. The in vitro assays demonstrated the high anti-diabetic activity of TT-AgNPs, and in vivo studies on streptozotocin-induced diabetic mice showed significant improvements in blood sugar levels and histological analysis of pancreatic and liver samples. These findings indicate the effective anti-diabetic properties of biosynthesized TT-AgNPs.

Summary: The metabolome of strawberries at harvest determines their storage capacity. Dynamics of volatile production during storage of strawberries grown under different drainage ratios were evaluated. Various non-target VOCs analysis showed that aldehydes content decreased over the storage period, while the esters and furanones increased as aroma compounds in strawberry ripening. The release of VOCs linked to fruit decay was delayed in the groups given relatively little water. Changes in firmness, total soluble solid content, anthocyanin content, and antioxidant activity supported the slower over-ripening tendency of the groups with less water. The study demonstrated that preharvest drainage changes during cultivation affected fruit quality during strawberry storage, and optimal drainage ratio could delay stress and senescence, ensuring strawberry yield. VOCs could be considered an early indicator for strawberry fruit shelf-life.

Summary: The aim of this study was to isolate endophytes from the roots of Rhazya stricta and evaluate their potential in improving the growth of drought-stressed sunflower seedlings. The isolated endophytic fungus was found to enhance the growth attributes of rice varieties and contribute to the improvement of sunflower growth under drought stress. The fungal strain was identified as Fusarium proliferatum and its beneficial effects were attributed to the regulation of phytohormones and stress-related metabolites.

Summary: Industrial effluents cause water pollution and impact aquatic and terrestrial life. This study isolated efficient fungal strains, identified as Aspergillus fumigatus (SN8c) and Aspergillus terreus (SN40b), from the aquatic environment. These isolates were chosen for their ability to efficiently decolorize and detoxify Remazol brilliant blue (RBB) dye, commonly used in various industries. Among 70 different fungal isolates screened, 19 demonstrated dye decolorization capabilities, with SN8c and SN40b showing the highest decolorization capabilities in liquid medium. The study showed the potential of these indigenous aquatic fungi to restore contaminated sites and support aquatic and terrestrial life.

Summary: The rhizobacterium Pantoea conspicua was found to promote the growth of sunflower seedlings under arsenate stress. Arsenate exposure compromised sunflower growth due to the accumulation of higher concentrations of arsenate and reactive oxygen species (ROS) in the seedlings' tissues. However, inoculation of the seedlings with P. conspicua alleviated arsenate stress by implementing a multilayered defence mechanism. P. conspicua removed 75.1% of the arsenate from the growth medium and helped the seedlings produce higher levels of antioxidants, resulting in improved growth and reduced oxidative damage.

Summary: This study investigated the effects of darkness and different light wavelengths on the metabolomics and anti-cancer activity of ginseng extracts. The results showed that dark treatment and blue-LED treatment increased the content of active compounds in ginseng extracts and promoted apoptosis of cancer cells and inhibition of the MAP kinase pathway. Therefore, dark treatment may effectively enhance the pharmacological potential of ginseng.
