This polymer is biodegradable via PHB depolymerases (PHBDs). Literature survey reveals that there are no comprehensive updates on PHBDs and in the current review, details regarding extracellular and intracellular forms of the enzyme are presented. Phylogenetically diverse PHBD-producing microorganisms are prevalent in a variety of natural and man-made habitats. These enzymes have been purified from different organisms and are seen to be active over a wide range of pH and temperatures. In general, extracellular PHBDs are made up of four constituents - signal peptide, catalytic domain [with a signature triad (serine, aspartate and histidine) and an oxyanion histidine], linker domain and substrate binding domain that enable degradation of PHB. Intracellular PHBDs have been mainly studied in bacterial genera such as Rhodobacter, Rhodospirillum, Ralstonia, Zoogloea, Pseudomonas, Sinorhizobium and Bacillus. Genes encoding them have been identified, characterized and cloned in other organisms. PHBD producers are envisioned to play a significant role in developing ecofriendly methods for removing PHB wastes thereby highlighting their practical relevance. Development of appropriate consortia including diverse PHBD producers and their introduction in waste disposal sites would enable treatment of PHB containing wastes. By using bioinformatics and synthetic biology-based approaches, further investigations on PHBDs from unexplored microorganisms can be undertaken and their role in the bioplastic waste management can be unraveled.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"380 ","pages":"124925"},"PeriodicalIF":8.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143708004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores the effectiveness of in-situ modification of commercial NF270 membranes using two monomers for the removal of 1H-benzotriazole (BTA). For the first time, this work investigates the physicochemical properties of commercial NF270 membranes grafted with these two monomers, 3-(trimethoxysilyl)propyl methacrylate and 2-(diethylamino)ethyl methacrylate, using different surface characterization techniques. The study also evaluates the performance of both unmodified and modified membranes in the rejection of BTA and compares the results with state-of-the-art monomers. The 2-(diethylamino)ethyl methacrylate-grafted membranes show a modest enhancement of 12 % in BTA rejection. In contrast, the 3-(trimethoxysilyl)propyl methacrylate-modified membranes exhibit a remarkable 107 % improvement in BTA rejection compared to the virgin NF270 membrane, achieving the highest increase in OMP removal among current state-of-the-art monomer-modified membranes reported in previous research. This approach effectively removes BTA primarily through the mechanisms of size exclusion and hydrophobic interactions.

We investigate the stage differences in the impact of digital government on carbon emissions from a life cycle perspective of digital government development through nonlinear modeling based on data from 159 countries from 2003 to 2022. Our research found that: (1) Digital government has a non-linear effect on carbon emissions in an inverted \"U\" shape of \"first promote and then inhibit\", with an inflection point value of 0.328. Digital government can significantly inhibit carbon emissions when it exceeds the inflection point value. Mechanism analysis shows that digital government has a suppressing effect on carbon emissions by improving government efficiency, government regulatory quality, and business environment. In addition, this inverted \"U\" relationship is more pronounced in developed countries and countries with outward-looking economies. (2) Among the components of digital government, information infrastructure and online services are the key drivers of this inverted \"U\" relationship. Threshold analysis shows that when the information infrastructure index exceeds 0.437 or the online service index exceeds 0.606, the digital government shows a significant inhibition of carbon emissions. (3) Moderation analysis shows that energy consumption structure, employment structure, and e-participation of residents negatively moderated the inverted U-shaped relationship between digital government and carbon emissions, and they flattened the original inverted U-shaped curve.

This gap is particularly pronounced in the arid and semiarid zones of China (ASZC), which are highly vulnerable to climate change and human disturbances. To address this issue, this study focuses on the ASZC as the research area and employs an integrated research framework to clarify the spatiotemporal dynamics of land use, NCPs and their interactions under three Sustainable Development Goals and Shared Socioeconomic Pathway (SDGs-SSPs) scenarios between 2030 and 2060. The results indicate that: (1) forest area is projected to expand, and grassland area slightly decrease in future scenarios; (2) high-density forest and grassland in the southeastern part of the ASZC have significantly increased the provision of NCPs; (3) trade-off between NCPs is primarily observed between the regulation of water quantity, location and timing (NCP6) and the formation, protection and decontamination of soils and sediments (NCP8). Furthermore, NCP bundles that were previously dominated by habitat creation and maintenance (NCP1)-regulation of climate (NCP4)-NCP6 have shifted to NCP1-NCP4 in and NCP1-NCP8 bundles across different SDGs-SSPs scenarios.

To address this, we conducted a two-year cotton (Gossypium hirsutum L.) field experiment under drip irrigation in arid northwestern China. The study assessed the effects of two EENFs (ESN and SuperU) and conventional urea, applied at 120 and 240 kg N ha^-1, on surface CH₄ uptake and profile diffusion. ESN is polymer-coated urea, and SuperU is a stabilized N fertilizer containing urease and nitrification inhibitors. ESN and SuperU were fully side-banded at pre-plant due to their low solubility and tendency to float, while urea, with its higher solubility, was applied via fertigation. We measured surface CH₄ uptake using static chambers and CH₄ concentrations at 5, 15, 30, and 60 cm soil depths using in-situ diffusive sampling. CH₄ diffusion rates were calculated using the concentration gradient method. Soil ammonium, (NH₄⁺) and nitrate (NO₃^-) nitrogen concentrations, moisture, and temperature were determined. The results showed that, compared to urea, applying ESN and SuperU reduced cumulative surface CH₄ uptake (30.1 %-42.7 %) and increased soil NH₄⁺ (30.1 %-33.5 %) and NO₃^- (20.6 %-46.0 %) concentration. Soil CH₄ concentration decreased with depth, with the highest CH₄ oxidation in the 15-30 cm layer. CH₄ concentrations in the 5-50 cm layer and diffusion rates in the 0-60 cm layer were positively and negatively correlated with soil moisture, respectively, but weakly influenced by N fertilizer treatment. Dry-wet alternation and low soil moisture limited the response of CH₄ concentration and diffusion to changes in mineral N. Additionally, weak correlations were found between surface CH₄ uptake rates and profile diffusion rates across all treatments. The reduced surface CH₄ uptake with ESN and SuperU was mainly due to increased NO₃^- concentrations.

For large-scale predictive mapping, very few practical implementations have attempted to clarify how well indicator models can be built from large covariate sets combined with spatial proxies. This paper summarizes the performance of the weighted indicator-based random forest model which was used to predict exceedance probabilities for several potentially toxic elements (PTEs) in Czech farmland. The method was implemented for data mining in the Czech high-density monitoring data which had to be firstly regressed to achieve analytical harmony, and the reliability of the regression-based harmonisation was used as the input weights for the final model. The indicator-based models were trained for each PTE (As, Be, Cd, Co, Cr, Cu, Hg, Ni, Pb, V, and Zn) with two different sets of indicators, reflecting the two-tier nature of the Czech safety guidelines, which differentiate between soil textures of topsoil. The two separate predictive outputs are combined into a single probability map using a pragmatic meta-model of linear weights derived from a soil texture map generated by a compositional spatial model. Through validation with data splitting, the accuracy of the models showed relatively high predictive power for the probability distributions, but with pronounced differences between PTEs as the root mean square error in terms of exceedance probabilities ranged from 11 % (V) to 32 % (Cd and Cr) for independent validation. In addition, models based on high-resolution auxiliary variables allowed a meaningful and quantitative identification of the most important natural and anthropogenic drivers for areas with an increased rate of non-compliance with the protection thresholds for cultivated soils. Variable importance calculations showed the dominant influence of spatially explicit covariates (represented by geographical distances to quantile-based groups of points), but still significant contributions from other predictors. Among the natural factors, lithological information came to the fore, mainly due to continuous response variables such as mineral exploration density or geophysical ancillary variables (from remotely sensed gravimetry and radiometry).
