“…It embraces strong adhesive attributes and has the capacity to develop non-odorous, semi-opaque, and oxygen-proof films [125,174]. Pullulan exhibits applications in the bioremediation of industrial waste streams [29], biosorption of heavy metals [67,175,176], harmful dyes [177][178][179], antibiotics [180,181], and other pollutants [182] in water due to its robust adhesive attributes. The use of synthetic polymers for food packaging has increased over time due to their mechanical and thermal attributes, but the decomposition of these polymers leads to the production of harmful gases [183].…”

Industrial evolution and agricultural expansion, explained by continuing population growth, have rendered enormous problems for the world throughout the past few decades, primarily because of waste generation. To reduce environmental impact and dependence on fossil fuels, scientists have explored replacing synthetic polymers with environmentally friendly and sustainable alternatives in many emergent applications. In this regard, microbial biopolymers have gained special attention. Many biopolymers originating from various strains of bacteria, fungi, and algae have been reported and their possible applications have increased rapidly. This review focuses on the wide range of microbial biopolymers, their characteristics, and factors influencing their production. The present study also describes the environmental applications of microbial biopolymers. The use of these biopolymers is very attractive as a value-added and sustainable approach to wastewater treatment. By acting as adsorbents, coagulants, and flocculants as well as filters in membrane processes, microbial biopolymers shine as promising solutions beyond conventional methods. They can be integrated into various stages of the treatment process, further enhancing the efficiency of wastewater treatment methods. Microbial biopolymer applications in bioremediation and soil stabilization are also reviewed. Several studies have demonstrated the strong potential of biopolymers in soil improvement due to their ability to minimize permeability, eliminate heavy metals, stabilize soil, and limit erosion. Challenges related to scaling up and the downstream processing of microbial biopolymers, as well as its future perspectives in environmental applications, are also discussed.

“…The coating reduced the toxicity on bacteria and crustaceans, although it increased the bioaccumulation in the latter organism, for which respiration levels also appeared altered. However, no adverse effects were noted for NP concentrations up to 200 mg per liter [218]. Ceria NPs were also studied for their effects on river biofilm communities and were showed to exert selection pressure that ultimately altered the composition of the microbial community [219].…”

Nanostructured Ceria: Biomolecular Templates and (Bio)applications

et al. 2021

Ceria (CeO2) nanostructures are well-known in catalysis for energy and environmental preservation and remediation. Recently, they have also been gaining momentum for biological applications in virtue of their unique redox properties that make them antioxidant or pro-oxidant, depending on the experimental conditions and ceria nanomorphology. In particular, interest has grown in the use of biotemplates to exert control over ceria morphology and reactivity. However, only a handful of reports exist on the use of specific biomolecules to template ceria nucleation and growth into defined nanostructures. This review focusses on the latest advancements in the area of biomolecular templates for ceria nanostructures and existing opportunities for their (bio)applications.

“…Literature shows that, D. magna is one of the most commonly used bio-models for aquatic toxicology tests due to its high sensitivity to environmental changes and chemicals, its large size compared to other species, and its ease of use in vivo (Gaiser et al 2009). Several previous studies reported the use of different nanoparticles types (ZnO, CuO, CeO 2 and AgNPs) to assess their toxic effects on D. magna physiology and behaviour (Fan et al 2017, Dai et al 2020, Milenković et al 2021, Galhano et al 2022, Ribeiro Santos-Rasera et al 2022.…”

Developmental effects of a binary mixture of nanoparticles (NPs) composed of Titanium dioxide (TiO2) and iron oxide (Fe2O3) were identified in Daphnia magna using a chronic toxicity test. Survival, growth, reproduction, and age at first brood were measured throughout 21 days of exposure. Results from this study demonstrated that mixture exposure to NPs (TiO2 and Fe2O3) significantly affects the development of D. magna to maturation and disturbs the reproductive performance in a dose-dependent manner and beginning from the lower dose. Mortality recorded in control group (1 ± 0.365) was significantly lower than in experimental groups (6.94 ± 0.193, 7.19 ± 0.188, 7.62 ± 0.125, 7.62 ± 0.155 individual, in C1, C2, C3, and C4, respectively). Moreover, swimming performances (F4, 35 = 112.9, df = 4, p<0.0001) and heart rate (F4, 25 = 19.37, df = 4, p<0.0001) were also affected. In conclusion, the interaction of binary mixtures can exacerbate toxicological effects that have significant implications for appropriately assessing the ecotoxicological effects of emerging pollutants. Further investigation and the results reported in the present study will be useful in environmental policies.
