Urban rivers are affected at different levels by the intensification of human activities, representing a serious threat to the maintenance of terrestrial life and sustainable urban development. Consequently, great efforts have been dedicated to the ecological restoration of urban rivers around the world, as a solution to recovering the environmental functionality of these environments. In this sense, the present work aimed to investigate the effectiveness of interventions carried out aimed at the recovery of urban rivers, through a systematic review of the literature between 2010 and 2022, using the search term "rivers recovery." The results showed that there have been notable advances in the implementation of river recovery programs in urban areas around the world between the years analyzed. The ecosystems studied were affected, for the most part, by the increase in the supply of nutrients from domestic and industrial effluents, in addition to having highly urbanized surroundings and with several changes in land use patterns. The preparation of this literature review made it possible to demonstrate that the effectiveness of river recovery is extremely complex, since river recovery projects are developed for different reasons, as well as being carried out in different ways according to the intended objective.

Reactive dyes used in the textile industry can be harmful to aquatic organisms. This study aimed to evaluate the potential cyto/genotoxic effects of the Novacron® Bold Deep Navy reactive dye on fish Astyanax lacustris before and after treatment through a vertical flow constructed wetland system (VFCW). Micronucleus test (MN), cellular morphological changes (CMC), and the comet assay were used to assess the effects of the dye in erythrocytes. During the experiment, A. lacustris specimens were exposed to sublethal concentrations (10, 20, 30, and 40 mg/L) of Novacron® Bold Deep Navy dye for 96 h. Results showed that the dye caused MN formation (27), DNA damage, and several types of CMC (3513) in all tested concentrations on A. lacustris. Notably, analyses were significant (p © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

Advances in polyhydroxyalkanoate (PHA) production from renewable waste materials using halophilic microorganisms: A comprehensive review

引用

Science of the Total Environment 2025年 963卷 178452页

Polyhydroxyalkanoates (PHAs) are biodegradable and biocompatible polymers that can replace conventional plastics in different sectors. However, PHA commercialization is hampered due to their high production cost resulting from the use of high purity substrates, their low conversion into PHAs by using conventional microbial chassis and the high downstream processing cost. Taking these challenges into account, researchers are focusing on the use of waste by-products as alternative low-cost feedstocks for fast-growing and contamination-resistant halophilic microorganisms (Bacteria, Archaea…). This is of great importance since these extremophiles can use low-cost substrates, produce high PHA content of copolymers or different PHA monomer compositions. They can present high potential for reducing the costs of PHA fermentation and recovery processes, making their use in commercial applications easier. However, little is known about the potential of halophiles in advancing the PHA production from renewable waste materials at lab-scale and their successful implementation at industrial-scale. This review presents actual advances in PHA production by halophilic pure/engineered species (e.g. Haloferax mediterranei, Halomonas spp.) and mixed microbial consortia (MMC) using organic waste streams. The development of optimal PHA production process involves robust genetic engineering strategies, advanced fermentation processes using mixed microbial consortia versus pure/engineered strains as well as algal biomass as feedstocks. © 2025 Elsevier B.V.

Fipronil (FP) is a neurotoxic insecticide widely used in agriculture for pest control, being bees non-target organisms for it. However, there are no data on the possible genotoxic effect of FP sub-lethal concentrations on the brain of bees. Through comet assay and routine morphological analysis, we aimed to analyze the genotoxicity of FP at two concentrations estimated in the field on the brain of foraging workers of Bombus atratus. B. atratus workers were collected in the field and transferred to the laboratory, where they were kept in a controlled environment (26 ºC;70% relative humidity) for 96 hours. Bioassays were performed by offering sucrose solution (70%) for the control and two different solution concentrations of FP for the experimental group, 2.5 ppb and 3.5 ppb respectively. Groups were fed ad libitum. After exposure, workers were crio-anesthezied (4ºC;20 min) and their brains were dissected and prepared for comet assay and morphological analysis. The technique comet assay showed that the concentration of 3.5 ppb FP presented a significant genotoxic effect on brain nucleus cells compared with the control. We did not find genotoxic effects on the brain nucleus cells for exposition at 2.5 ppb FP. Morphology showed changes of the mushroom bodies of the bees studied. In both concentrations, the basal region of the calyx presented signs loss of synapses;intercellular spaces between the inner compact and inner noncompact cells, and pyknotic nuclei. However, the concentration of 3.5 ppb induces disruption of the cell types of Kenyon cells of the glomeruli. This data may signal that the insecticide may affect the performance of the foraging workers of bumblebees. © 2023, The Authors. All rights reserved.

Two organic-inorganic hybrid zinc phosphites incorporating 1,2,4,5-tetrakis(imidazol-1-ylmethyl)benzene (TIMB) molecules were synthesized under hydro(solvo)thermal methods and structurally characterized by single-crystal X-ray diffraction (SCXD). Interestingly, the solvent ratio of water to dimethylformamide induced the formation of a new compound of Zn2(TIMB)0.5(HPO3)2·3H2O (1) and our previously reported structure of Zn2(TIMB)0.5(HPO3)2·H2O (2). Additionally, their dehydrated crystals (1a and 2a) were prepared through heat treatment at 150 °C. SCXD and powder X-ray diffraction showed that all four compounds share the same framework formula of Zn2(TIMB)0.5(HPO3)2 but exhibit a huge difference in their inorganic components and final structures. In 1 and 1a, the inorganic units formed two-dimensional zincophosphite layers, while in 2 and 2a, they formed one-dimensional chains. The inorganic parts of 1 (1a) and 2 (2a) were bridged with TIMB linkers, resulting in 3D structures with rectangular and tubular windows, respectively. Furthermore, 1 was coated on the screen-printed carbon electron as a hybrid material, displaying excellent performance while having a linear relationship with an R2 value of 0.99 within the concentration range of 10-10 to 10-6 mol/L for detecting tryptamine (Try) molecules. Moreover, the results showed that 1 exhibits an ultralow limit of detection of 5.43 × 10-11 mol/L and high specificity toward Try over histamine, ascorbic acid, uric acid, and glucose. The synthesis, structural diversity, stability, and sensing ability are also discussed. © 2023 American Chemical Society.

Journal of Geoscience and Environment Protection 2023年第5期11卷 1-16页

作者： Taís Silva Sousa Clezio Júnior Teixeira Viegas Helenilza Ferreira Albuquerque Cunha Alan Cavalcanti da Cunha Graduate Program in Environmental Sciences Federal University of Amapá Macapá Brazil Graduate Program in Tropical Biodiversity Federal University of Amapá Macapá Brazil Graduate Program in Biotechnology Federal University of Amapá Macapá Brazil

Drainage system is a poorly investigated basic sanitation and urban planning issue in the Amazon, which is often related to flooding processes and public health. The aim of the present research is to correlate Preliminary Risk of Flooding (PRF) to independent variables, based on the following methodology: 1) identifying and classifying risk areas by using the Geographic Information System (GIS) and 2) statistically correlating risk to sanitary and environmental variables. Results have shown that preliminary risk is correlated to, at least, seven sanitary and environmental variables, depending on flood influence area;and there are significant correlations observed in the rainy season interval [probability or significance (p) 0.05]. In conclusion, PRF is higher in the rainy season, but it is spatially influenced by the elevation of terrain, number of flooding points, drainage typology and environmental Salubrity Index (ESI) of neighborhoods, which directly affect the water quality in nearby groundwater wells (Total Coliforms, nitrate (NO₃) and ammonia (NH₃)). However, this influence can eventually significantly change in the dry season.

Leaves of the carnivorous sundew plants (Drosera spp.) secrete mucilage that hosts microorganisms, but whether this microbiota contributes to prey digestion is unclear. We identified the acidophilic fungus Acrodontium crateriforme as the dominant species in the mucilage microbial communities, thriving in multiple sundew species across the global range. The fungus grows and sporulates on sundew glands as its preferred acidic environment, and its presence in traps increased the prey digestion process. A. crateriforme has a reduced genome similar to other symbiotic fungi. During A. crateriforme–Drosera spatulata coexistence and digestion of prey insects, transcriptomes revealed significant gene co-option in both partners. Holobiont expression patterns during prey digestion further revealed synergistic effects in several gene families including fungal aspartic and sedolisin peptidases, facilitating prey digestion in leaves, as well as nutrient assimilation and jasmonate signalling pathway expression. This study establishes that botanical carnivory is defined by adaptations involving microbial partners and interspecies interactions. © The Author(s) 2024.
