Abstract:
... Ocean acidification and plastic pollution are considered as potential planetary boundary threats for which crossing certain thresholds could be very harmful for the world's societies and ecosystems well-being. Surface oceans have acidified around 0.1 units since the Industrial Revolution, and the amount of plastic reaching the ocean in 2018 was quantified to 13 million metric tonnes. Currently, bo ...

Abstract:
... Environmental acidification impairs microorganism diversity and their functions on substance transformation. Rhodococcus is a ubiquitously distributed genus for contaminant detoxification in the environment, and it can also adapt a certain range of pH. This work interpreted the acid responses from both phenotype and metabolism in strain Rhodococcus biphenylivorans TG9ᵀ (TG9) induced at pH 3. The p ...

Abstract:
... Synergism between different types of polysaccharides is important to imparting textural preferences and decreasing product costs. In this study, Nicandra physalodes (Linn.) Gaertn. pectin (NPGP) was found to synergistically interact with sodium alginate (SA) under an acidification process by glucono-δ-lactone (GDL) addition. This synergistic interaction led to the formation of much stronger NPGP/S ...

Abstract:
... With an increasing production and use of engineered nanoparticles (ENPs), inevitably grows their release into the environment. This makes it important to determine in what quantitates they occur in aquatic systems like seawater. However, even when using the most sensitive ICP-MS technique, quantification of very low seawater concentrations of ENPs is still concept rather than the fact. To approach ...

Abstract:
... Many lactose-free dairy products are produced using commercial lactase, but not without problems such as the sweetish taste due to the presence of free glucose and galactose. The aim of the present study was to obtain a lactose-free version of direct-acidified mozzarella without using the enzyme, but removing lactose by curd washing and pressing. The best results were obtained with double curd was ...
... Biotreatment of high load hydrogen sulfide (H₂S) can lead to rapid acidification of a bioreactor, which greatly challenges the application of bio-desulfurization technology. In this study, the bio-desulfurization performance was improved by enriching acidophilic mixotrophic sulfur-oxidizing bacteria (SOB) by adding organics under extremely acidic conditions (pH < 1.0). A biotrickling filter (BTF) ...
... Effect of soluble soybean polysaccharides (SSPS) and acidic condition on the bread staling of crumb and crust were evaluated in bread characteristics, water migration, starch retrogradation, and flavor. Bread characteristic analysis showed SSPS and acidic conditions significantly improved bread quality during storage, maintaining crumb softness. The staling rate of the synergistic group under SSPS ...
... The impact of antibiotics on the environmental protection and sludge treatment fields has been widely studied. The recovery of hydrogen from waste activated sludge (WAS) has become an issue of great interest. Nevertheless, few studies have focused on the impact of antibiotics present in WAS on hydrogen production during dark anaerobic fermentation. To explore the mechanisms, sulfamethoxazole (SMX) ...

Abstract:
... Ca-Fe-Si material (CIS), a novel composite material rich in calcium, iron, manganese and silicon showed marvelous immobilization properties for heavy metal(loid)s in soils. To elucidate the acid stability of Cd fixed by CIS (CIS-Cd) and the underlying immobilization mechanisms, the acid dissolution characteristics of CIS-Cd were investigated by using acid titration method and X-ray diffraction (XR ...

This article proposes a framework for ex-ante life cycle assessment (LCA) of biopolymers at low TRL, including: (i) scale-up; (ii) scenarios for processes and modelling choices; (iii) comparison with a fossil-based polymer, considering material substitution factors. The framework was applied to analyse a mango kernel starch (MKS) film and compare it with low-density polyethylene (LDPE). Mango seed ...

Abstract:
... Recalcitrant and toxicological membrane-making wastewater displays negative impacts on environment, and this is difficult to treat efficiently using conventional hydrolytic acidification. In this study, a novel electro-assisted biological reactor with micro-aerobic cathode (EABR-MAC) was developed to improve the biodegradation and ammonification of N, N-dimethylformamide (DMF) in membrane-making w ...

Abstract:
... Excessive N fertilization causes the deterioration of soil microbiome. It is therefore imperative to explore the response of the microbial community in excessively N-fertilized soil to reduce subsequent N supply (RCN) and organic fertilization (OF). Hence, this study used an excessively N-fertilized plot to conduct field experiment of wheat and maize rotation over four years to assess the effects ...

Abstract:
... This study investigates the environmental impacts of using two different power groups in a fixed-wing Unmanned Aerial Vehicle (UAV). The first power group consists of a conventional electric motor, a lithium polymer battery and a propeller. The second power group is the hybrid power group formed by adding the Proton Exchange Membrane (PEM) fuel cell. The life cycle assessment (LCA) method is appli ...
... Climate change leads to an increase in water acidification and temperature, two environmental factors that can change fish appetite and metabolism, affecting fish population in both wild and aquaculture facilities. Therefore, our study tested if climate change affects gene expression levels of two appetite-regulating peptides – Neuropeptide Y (NPY) and Cholecystokinin (CCK) – in the brain of tamba ...

Abstract:
... Aquaculture is growing to meet the increasing demand for aquaculture products but is not free of environmental impacts. One solution is to improve how feed are formulated, limiting the environmental impact of fish production. Multiobjective (MO) formulation, which aims for a compromise between lower cost and lower environmental impacts, appears to be a promising solution to reduce the environmenta ...

Abstract:
... Studies on the impact of ocean acidification on marine organisms involve exposing organisms to future acidification scenarios, which has limited relevance for coastal calcifiers living in a mosaic of habitats. Identification of tipping points beyond which detrimental effects are observed is a widely generalizable proxy of acidification susceptibility at the population level. This approach is limit ...

Abstract:
... Gregarious behaviours are common in animals and provide various benefits such as food acquisition and protection against predators. Many gregarious tropical species are shifting poleward under current ocean warming, creating novel species and social interactions with local temperate taxa. However, how the dynamics of these novel shoals might be altered by future ocean warming and acidification rem ...

Abstract:
... Coastal systems experience diel fluctuation of pCO₂ and cadmium (Cd) pollution; nevertheless, the effect of fluctuating pCO₂ on Cd biotoxicity is poorly known. In this study, we initially performed the isotopically enriched organism bioassay to label Tigriopus japonicus with ¹¹³Cd (5 μg/L) to determine the Cd accumulation rate constant (kₐccᵤ) under ambient (400 μatm) and steadily (1000 μatm) and ...

Abstract:
... Climate change stressors (e.g., warming and ocean acidification) are an imminent challenge to the physiological performance of marine organisms. Several studies spanning the last decade have reported widespread effects of warming and acidification on marine fishes, especially teleosts, but more work is needed to elucidate the responses in marine elasmobranchs, i.e., sharks and rays. Dispersal capa ...
