Summary: Algae-based wastewater treatment technologies have great potential for economic and environmental benefits, but have not yet been successfully applied in municipal wastewater treatment plants for nitrogen and phosphorus removal. This paper reviews the literature and analyzes the reliability and readiness level of five types of reactors. The study shows that reactors with higher control over technological parameters are more reliable, but algae harvesting and additional costs are barriers to their deployment.

Summary: Electrodialysis is a promising process for nutrient removal and recovery from wastewater, but limited knowledge exists regarding its application. Increasing voltage, membrane area, and number of cells can improve recovery rate, but ion mobility is influenced by various factors. Hybrid processes enhance efficiency, but costs and fouling remain challenges to be addressed.

Summary: Attached algal cultivation systems have the potential to improve productivity and efficiency, but there is a lack of understanding of algae-substrate interactions. This study presents a design for an indoor flow way photobioreactor and assesses the effects of key parameters on the attached cultivation of filamentous green algae. The results demonstrate that carefully designed indoor reactors offer advantages for studying algae-substrate interactions in terms of repeatability, flow uniformity, and cost-effectiveness.

Summary: The study found that green roofs may leach nutrients, with the leaching degree closely related to the initial nutrient content of the medium. Nutrient leaching from both laboratory and field observations decreases over time, primarily due to cumulative inflow, and the nutrient leaching is mainly sourced from the medium.

Summary: Filamentous macroalgae, specifically Oedogonium calcareum and O. pringsheimii, show potential for innovative treatment of municipal wastewater by effectively removing residual nutrients. Through on-site assessment, it was found that both species are ideal candidates for bioremediation due to their high productivity and superior performance in reducing dissolved inorganic nitrogen and dissolved reactive phosphorus concentrations in wastewater effluents. Further research is needed to confirm their suitability for long-term applications.

Summary: Microalgae cultivation is effective in reducing pathogens and purifying wastewater, but a comprehensive understanding of the risks is still needed. Different methods were used to explore microbial community and pathogen presence, showing that media and sampling locations have an impact on community structure and pathogenic loads. The main detected pathogens were Arcobacter and Elizabethkingia (mainly in wastewater), with a significant presence of Aeromonas in all samples. Raceways show potential as an effective biotreatment, with most retained pathogens being released in the outlet and only a small part settling in the biomass.

Summary: Uranium contamination is a widespread issue caused by natural and human activities. However, the molecular mechanisms underlying uranium resistance in bacteria are still not well understood. This study investigated the resistance mechanisms of Cupriavidus metallidurans NA4 to toxic uranium concentrations. Through the increased expression of a specific small periplasmic protein, PrsQ2, the bacteria were able to form periplasmic uranium-phosphate precipitates, thus improving their resistance to uranium.

However, due to antibiotic resistance, alternatives such as probiotics are being explored. This study compared the effects of different strains of Lactobacillus and Streptococcus salivarius on oral biofilms. It was found that certain Lactobacillus strains reduced the pathobiont A. actinomycetemcomitans, while S. salivarius strains were more effective against other pathobionts.

Summary: A sequential batch reactor (SBR) was used to produce a self-protected CaCO3-precipitating biomass powder (CPB) that can hydrolyze urea and reduce nitrate. The addition of CPB to mortar showed higher crack healing ratio compared to Bacillus sphaericus spores. CPB also revealed a corrosion inhibition effect equivalent to nitrite, making it a suitable bio-additive for crack closure and corrosion inhibition in cementitious composites.

Summary: A bacteria-based self-healing concrete was proposed for autonomous repair of micro-cracks, using vegetative cells of Bacillus sphaericus encapsulated in alkali activated lightweight aggregate (LWA) made from fly ash and Sidoarjo volcanic Mud (Lusi). The study showed that the healing performance of the bacteria decreased significantly when cracks were fabricated at a later age. Additionally, the fly ash-based LWA carrier exhibited excellent autogenous healing in young mortar.

Summary: In this study, the removal of N,N-Dimethylformamide (DMF) was evaluated using a lab-scale biofilter for 472 days under mesophilic and thermophilic conditions. The biofilter achieved an average removal efficiency of 99.7% at ambient temperature with an inlet load of 297g DMF/m3 h and an EBRT of 10.7 s. However, a decrease in EBRT and an increase in temperature led to a decrease in removal efficiency. Microbial analysis revealed that the dominant bacteria were Rhizobiaceae and Alcaligenaceae, but their abundance decreased with increasing temperature. Overall, biofiltration showed promise for removing DMF from waste gas streams.

Using this model, the researchers validated the multifaceted effects of L-arginine on the oral biofilm, including inhibiting the growth and incorporation of pathogenic species, reducing biofilm thickness and volume, and producing specific metabolic products. This drip flow reactor setup shows promising potential for studying the spatiotemporal behavior of a multispecies periodontal community.

Summary: We propose a photonic integrated circuit design that adds practicality and new functionalities to optical applications like optical microscopy. This design enables the generation of a far-field structured UV illumination pattern with a fringe period of 370 nm, a fringe visibility of 0.83, and a radiant intensity of 0.49 mW. By using single mode waveguides with low propagation losses, diffraction gratings, a beam splitter, a phase shifter, fluorescent gratings, and a collecting lens, the current PICs experimentally demonstrate the Moiré pattern at the heart of optical resolution enhancement and achieve a doubling of optical resolution in the direction of illumination.

Summary: As part of the circular bio-economy paradigm shift, waste management has shifted focus towards producing added-value compounds. The use of mixed culture bioprocesses for converting waste to platform chemicals has gained interest, but these processes often lack microbiological diversity and are prone to disturbances. To address this, flow cytometry was used to monitor a lactic acid chain elongation process for caproic acid production, allowing for qualitative and quantitative assessment. Specific community types were identified and correlated to functionality and genotypic diversity, and machine-learning algorithms showed high accuracy in predicting production rates.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
