Summary: Mycoremediation with halophilic Aspergillus sydowii showed significant removal of PAHs in a hypersaline environment, mainly through biotransformation. Transcriptomic analysis revealed that A. sydowii grown in hypersaline conditions upregulated numerous genes related to PAHs metabolism, while the activity of traditional enzymes like lignin modifying enzymes remained unchanged. The significant upregulation of the chloroperoxidase gene may be associated with fungal detoxification processes.

Summary: This study focuses on the development of economically feasible strategies for the enhanced remediation of anthracene and its conversion into biofuels. By using specific strains and metabolites, the strategies developed showed higher production of surface-active metabolites and a maximum biodegradation rate. The conversion of anthracene into phthalic acid was confirmed, and the lipid produced by the strain showed improved fuel quality. The spent wash was found to be non-toxic and usable for ferti-irrigation.

Summary: This study evaluated the biodegradation of Chemical Oxygen Demand (COD) from bilge water using a sequencing batch reactor (SBR) combined with Bacillus licheniformis strain S2. Response surface methodology (RSM) was used to optimize the influencing variables of temperature, pH level, and inoculum concentration on the SBR system. The results showed efficient COD removal at optimal operating conditions with a high R-2 value in the biodegradation kinetics of COD.

Summary: The GTL process generates acidic wastewater with high COD content due to organic pollutants. Biological treatment using specific bacterial strains like Alcaligenes faecalis, Stenotrophomonas sp., and Ochrobactrum sp. can effectively reduce the organic pollutants in the wastewater, with mixed cultures showing tolerance to varying COD levels.

Summary: An investigation was conducted to understand the interaction of two polyaromatic hydrocarbon semi-volatile organic compounds, naphthalene (NAP) and benzo[ghi]perylene (BghiP), with different surfaces and media. Various techniques including confocal fluorescence microscope and infrared microscope were used to detect the concentration, time, and temperature-dependent changes of NAP and BghiP on surfaces. The study also estimated the sorption of NAP and BghiP on different surfaces and performed molecular dynamic simulations to understand their behavior on dust surfaces.

Summary: In this study, the degradation efficiency of mixed PAHs, especially anthracene, pyrene, and benzo(a)pyrene, was enhanced by using a biosurfactant and iron nanoparticles. The biosurfactant increased the bioavailability of PAHs in the aqueous environment, promoting bacterial settlement and growth. Iron nanoparticles increased bacterial biomass and PAHs adsorption, facilitating PAHs utilization by the bacterial consortia.

Summary: A series of difluoroborate fluorescent dyes with intramolecular charge transfer were synthesized and their properties were studied using both experimental and computational approaches. The size of the polyaromatic hydrocarbon side chains affects the photophysical properties of the dyes, especially their fluorescence quantum yield. Interestingly, corannulene, which is typically considered to lower the emission brightness, exhibited the highest fluorescence quantum yield in the series. Additionally, weak H/F or H/H intramolecular repulsions impacted the properties of BF2-carrying fluorophores.

Summary: The Great Salt Lake contains two high salinity arms, where biodegradation of petroleum hydrocarbons is extensive but slower than in fresh- and sea-water. Less volatile hydrocarbons in weathered crude oil are degraded less extensively and slowly compared to sea or fresh-water. The diversity of substrates subject to degradation suggests that biodegradation is the ultimate fate of petroleum hydrocarbons entering the lake. However, the biodegradation rate is slower in this environment, and increasing it may be possible through nutrient supplementation with organic nitrogen.

Summary: This study examined the performance of an integrated photocatalysis and MBBR system in treating synthetic wastewater containing SMX. It was found that the integrated system could remove over 80.5% of SMX and 67.7-80.7% of COD. The introduction of photocatalysis had no impact on COD removal and significantly enhanced SMX removal. High-throughput analysis indicated that microbial community greatly altered due to photocatalytic oxidation stress. Microorganisms maintained metabolic activity, possibly due to the protection of carriers and microbial self-preservation.

Summary: This study systematically investigates possible reaction pathways leading to the formation of five-membered rings, focusing on the formation of acenaphthene and acenaphthylene from different sites on naphthalene and phenanthrene. The relative importance of new reaction pathways is explored based on experimental data, providing a more complete description of cross-linking in soot models and the formation of embedded five-membered rings.

Summary: This manuscript reports the synthesis of 2-Ar-5-(4-(4-Ar'-1H-1,2,3-triazol-1-yl)phenyl)-1,3,4-oxadiazoles as PAH-based aza-analogues of POPOP by Cu-catalyzed click reaction. The photophysical properties of the obtained products were investigated, and their sensory response to nitroanalytes was evaluated. Dramatic fluorescence quenching by nitroanalytes was observed in the case of pyrenyl-1-substituted aza-POPOP.

Summary: A special reactor with high active surface-to-volume ratio was used for investigating organic pollutants degradation in gasfield produced water through photoelectrocatalysis. After a simple evaporation process to reduce TDS, the distilled wastewater was treated again by photoelectrocatalysis, with a significant decrease in COD removal efficiency to 81%.

Summary: The only current treatment for celiac disease is a strict gluten-free diet, but there is a need for non-dietary alternatives to prevent damage from dietary transgressions. Recent therapies for CD focus on degrading gluten, regulating the immune response, and inducing immunological tolerance, with promising results seen in some phase III and II clinical trials.

Summary: This study aims to translate, culturally adapt, validate, and apply the Spanish version of the Coeliac Disease Questionnaire (CDQ) to a representative sample of Spanish teenagers and adults with coeliac disease (CD). The results show that the newly Spanish CDQ is an appropriate tool to assess the quality of life (QoL) of CD patients, with satisfactory internal consistency and test-retest reliability. The study also highlights the importance of identifying affected scales to address actions and support patients with chronic diseases such as CD.

Summary: Most gluten analysis methods are not effective for detecting hydrolyzed gluten proteins in certain foods and beverages. However, a method using G12/A1 moAbs can detect the immunogenic peptides that are responsible for the immune response in celiac disease. A specific and sensitive method based on G12/A1 LFIA was developed to detect gluten immunogenic peptides in beers labeled gluten-free or with low gluten content. The study found that some beers, despite being labeled gluten-free or low gluten, still contained immunogenic peptides that could cause symptoms and damage in celiac disease patients.
