Summary: This study aims to uncover the roles of biofilm in reducing N2O emission in a nitrifying IFAS system, using advanced technologies such as N2O microsensor and site-preference analysis. The biofilm was found to reduce N2O emission by inhibiting nitrite accumulation and promoting endogenous denitrification. It also reduced N2O emission by decreasing the dissolved oxygen level. The presence of biofilm in the IFAS system resulted in significantly lower N2O emissions compared to the solo sludge flocs, and this can be attributed to the high microbial diversity and unique enzyme composition of the biofilm.

Summary: This study aims to reduce excess sludge production in the biological activated sludge process by upgrading the MBBR process to an integrated fixed film-activated sludge (IFAS) process. Two scenarios were tested, with the first scenario reducing sludge production and the second scenario eliminating sludge generation completely. The results showed that operating the system as an IFAS process with complete solid retention time (SRT) can eliminate sludge production, although it may result in higher NO3 effluent concentration.

Summary: This paper presents the first long-term high-resolution study on N2O emissions in a vineyard, showing that organic fertilization results in emission peaks followed by a decrease in N2O fluxes. The study also found that emission factors varied depending on treatment and soil TOC content, and the corrected emission factors were lower than the IPCC reference value for fertilizer application emissions.

Summary: This study investigates the removal of sulfonamides in water treatment processes using fixed-film activated sludge membrane bioreactors (IFAS-MBRs). The results show that sulfonamides significantly inhibit the removal of COD and NH4+-N, but the average removal efficiencies of the tested sulfonamides are all over 94%. The study also identifies the degradation mechanisms of sulfonamides and characterizes the microbial community involved in their degradation.

Summary: This study analyzed the impact of hydroxylamine (NH2OH) on the production of NO and N2O by nitrifying bacteria in activated sludge reactors. The results showed that the presence of NH2OH was positively correlated with dissolved oxygen levels and led to an imbalance in NH4+ oxidation, resulting in increased NO and N2O production under high DO conditions. Furthermore, the coexistence of NO2- and NH2OH in the reactor contributed to a significant generation of NO and N2O through both biotic/abiotic hybrid pathways and heterotrophic denitrification pathway.

Summary: Volatile fatty acids (VFAs), produced through acidogenic digestion of sewage sludge, play a significant role in achieving carbon neutrality in wastewater treatment plants. However, there is limited research on VFAs production from sludge fermenters with membrane. In this study, VFAs from a pilot plant equipped with a membrane bioreactor and fed with real sewage sludge were monitored, and the optimal operation conditions were determined by investigating the effect of headspace volume (HdV).

Summary: Fire frequency in fire-dominated ecosystems may increase due to global warming, land-use change, and human pressures. This study examines the effects of changes in fire frequency and other fire history characteristics on soil C and N dynamics and microbial groups in Pinus pinaster forests in central Spain. The results show clear differences between unburned and burned stands, with the time elapsed since the last fire being the most important factor governing soil nutrient dynamics and microbial groups. Recovery to pre-fire values takes 30-40 years, and increased wildfire frequency only affects total C and nitrification rate inconsistently. The time interval between the last two fires is not a significant factor. The results suggest the strong recovery capacity of this ecosystem even under increased fire frequency.

Summary: The study evaluated the physical-chemical properties of NH4+ adsorption from aqueous solution by two zeolitic mixtures, one treated with NaCl and one untreated. The zeolitic mixture richer in mordenite and with high specific surface area adsorbed more NH4+ than the one richer in clinoptilolite and heulandite with a lower specific surface area. NaCl treatment increased the amount of NH4+ adsorbed by the zeolitic mixtures. The results suggest that modulation of NaCl treatment of zeolitic mixtures can be applied to obtain new materials for water remediation from NH4+ contamination.

Summary: This study compared the classical chloroform fumigation-incubation (CFI) and fumigation-extraction (CFE) methods with a physical method based on N-2 or CO2 high pressurization (N2HP or CO2HP) for microbial cell lysis in two different soils. The results showed that CO2HP was more efficient than the CFE method for causing microbial cell lysis, and the CO2 pressure value and duration were important factors for increasing extractable organic C. However, CO2HP may have caused the release of non-living organic C.

Summary: The development and use of new and renewable energy sources are urgently needed as the global energy crisis is approaching due to rapid population growth and overexploitation of fossil fuels. This study developed a novel technology to efficiently produce renewable liquid bioenergy from discarded wastes, by transforming sewage sludge into high-value medium chain fatty acids (MCFA). The use of free nitrous acid (FNA) pretreatment significantly increased the yield of MCFA in the anaerobic sludge fermentation process. However, direct addition of FNA inhibited the generation of total products due to its toxicity on live cells in the sludge. The study also investigated the mechanism of MCFA promotion by FNA pretreatment and found that it increased MCFA production rate by converting refractory materials into rapidly bioavailable substrates and favoring the growth of microorganisms related to MCFA production.

Summary: Weed control in urban and peri-urban orange orchards is challenging due to restrictions. Mulching with black plastic geotextile fabric is an alternative to tillage and herbicides. This study assessed the impact of long-term soil mulching on soil fertility, microbial community, and orange yield. Mulching increased soil organic C, cation exchange capacity, microbial biomass C, and promoted the establishment of a more efficient microbial community. The use of black plastic geotextile fabric improved soil fertility and increased orange yield.

This work aims to provide experimental data on PHA productivity and purity, considering process parameters for industrial scale-up. The results showed that the highest PHA content was obtained using the highest organic load during accumulation tests, and the adopted extraction protocol demonstrated high efficiency and purity.

The results showed that decreasing the organic loading rate improved the removal of organic matter but reduced PHA production. Additionally, the emissions of N2O were evaluated during the process. The study also achieved a PHA production of 24% w/w.

Summary: This study investigated the variations in immunoglobulin G (IgG) content, composition, mineral content, and fatty acid composition in the colostrum of Valle del Belice ewes, and evaluated the effect of lambing season. Results showed that the IgG content and Brix mean values were 40.35 g/L and 21.02%, respectively. The lambing season significantly influenced pH and somatic cell count, with higher values in winter. Palmitic, oleic, myristic, and stearic acids were the most common fatty acids in summer and winter seasons. Winter season increased the values of polyunsaturated fatty acids. Additionally, lambing season determined different mineral composition levels in colostrum, particularly copper and manganese.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
