Summary: This research investigates the biokinetic behavior of bacterial species in an UASB-MBR system treating urban wastewater with emerging contaminants using respirometric techniques. The results show that a decrease in organic loading rate leads to the disintegration of floc structure, dispersed growth, and weak interfloccular bonds. However, no toxicity or inhibition caused by the presence of emerging contaminants is observed.

Summary: Diagnosis of male infertility is usually based on medical history and semen analysis, but the latter rarely provides information on the causes of infertility. This study suggests that analysis of sperm mitochondrial function and ROS production could be a useful addition to routine semen analysis. Experiment results showed that mitochondrial function is related to sperm motility and morphology. Evaluating mitochondrial function, ROS production, and antioxidant capacity can complement routine semen analysis.

Summary: Despite being important in marine aquaculture, little is known about the physiological effects of hydrogen sulfide (H2S) on Atlantic salmon. Recent mass mortalities in recirculating aquaculture systems have highlighted the need for understanding tolerance thresholds and metabolic responses to this toxic gas.

Summary: The study found that deficiencies of different minerals resulted in distinct changes in PSI and PSII parameters in sunflower leaves, such as an increase or decrease in oxidized P700. Specific responses of parameters to each mineral deficiency allowed for diagnosis of the deficiency and identification of which mineral affected photosynthesis.

Summary: The hypoxic constraint on peak oxygen uptake was characterized in rainbow trout using different testing protocols and statistical models. The best-fit model was selected based on statistical criteria and the model's prediction of key hypoxic performance points. A curvilinear model with five strategically selected oxygen tensions was found to best describe the hypoxic performance of rainbow trout, with PAAS-50 as a promising metric for comparing hypoxic constraints across fish species.

Summary: This paper introduces a method for building a cucumber photosynthetic rate prediction model of whole growth periods, which is optimized using Support Vector Regression algorithm. The photosynthetic rate under different environmental conditions during the whole growth period was obtained and used as inputs to build the prediction model. Compared with other methods, the optimized Support Vector Regression model shows higher accuracy and better modeling results.

Summary: Pollutants in water pose serious threats to human health and the aquatic environment. Researchers use the photosynthetic inhibition method to detect the toxicity in water, specifically utilizing chlorophyll fluorescence parameters. However, the current indicators have limited sensitivity and can only detect a restricted range of substances. This paper proposes a method to construct a comprehensive toxicity effect performance index based on the fluorescence curve of algae. The results show that this method can detect a wider range of pollutants with improved sensitivity and stability.

Summary: The study found a mass dependence in the relationship between field metabolic rates and dynamic body acceleration, requiring coefficient corrections to account for estimation errors in differently sized individuals. Additionally, caution must be taken when applying predictive models developed on one size class to individuals of different sizes due to strong scale dependence in the relationship between metabolic rates and body acceleration.

Summary: The study found that cardiac responses of gilthead seabream to hypoxia and warming differed between swimming freely in a tank and being confined to individual respirometers, with spontaneous activity contributing to heart rate differences. Additionally, there was a significant linear relationship between heart rate and oxygen uptake rates, suggesting that respirometry techniques may bias metabolic trait estimates in some fishes.

Summary: This study evaluated the acute toxic effects of leachates from two landfills on bacterium Aliivibrio fischeri and activated sludge microorganisms. Reductions in leachate toxicity were observed after removal of ammonia and humic substances, indicating organic compounds were the primary pollutants responsible for the toxicity. A. fischeri showed greater sensitivity to pollutants compared to activated sludge microorganisms, but a strong correlation between their toxicity responses was observed, suggesting the use of respirometry assay to determine leachate toxicity.

Summary: Compared to suspended microalgae cultivation, attached microalgae cultivation for wastewater treatment has the advantages of low biomass recovery costs and high robustness. A quantified model was built to study the photosynthetic capacity of attached microalgae biofilm along its depth using dissolved oxygen microelectrode. The results showed that the photosynthetic rate decreased gradually with depth, but at a slower rate compared to the suspended system. In addition, the photosynthetic rate of attached microalgae biofilm had a high potential for growth with increasing light intensity.

Summary: This study compared the metabolic rates of two Australian native plant species during cryopreservation and found a significant reduction in metabolic rates, even in tissues that regenerated after cryopreservation. The response to cryopreservation stresses varied among different species. Measuring the metabolic rate of shoot tips provides important information for cellular energy production and shoot health after exposure to cryoprotective treatments.

Summary: This study demonstrates that tunable diatom micro/nanostructures can be produced by adjusting the solids retention time (SRT) of membrane bioreactors (MBRs). As the SRT increases, the porosity of diatoms decreases and the silicon content increases. The surface area and pore numbers of diatoms decrease linearly with SRT. Additionally, the efficiency of nitrate and phosphorus removal by diatoms changes with SRT.

Summary: This study compared the overall treatment performance and methanogenic populations in AnMBRs treating low strength wastewater containing simple and complex carbohydrates at decreasing HRTs. The results showed that decreasing HRTs improved the effluent quality and methane yield in AnMBR-A, while the effect on AnMBR-G was smaller and the methanogenic population decreased. The study also found that decreasing HRTs were mainly limited by slow biochemical reactions.

Summary: A mechanistic model was developed to assess the removal efficiency of pollutants in a wetland system, particularly in oil sands process-affected water (OSPW). The model simulated wetland mechanisms of chemical removal and showed that sustained wetland treatment is feasible. It is a helpful tool to evaluate the feasibility of treatment systems and to assess trade-offs in wetland design and operation.

Summary: This study examined the long-term phosphorus retention in Stormwater Treatment Areas (STAs) and identified the factors influencing their performance. The results showed that the operational performance of STAs improved over time. There were notable differences among individual STAs, with the co-precipitation of phosphorus with calcium playing a critical role in one of the STAs. This highlights the complexity of phosphorus removal in STAs and the need for site-specific management strategies.

Summary: The biogeochemical response to different flow conditions within two parallel flow-ways in Everglades Stormwater Treatment Area (STA)-2 was studied. It was found that there was a gradual decrease in the total phosphorus (TP) concentration from inflow to outflow for both emergent aquatic vegetation (EAV) and submerged aquatic vegetation (SAV) dominated systems, with EAV showing a higher reduction rate. Significant increase in TP concentration was observed in the SAV system under no flow condition, possibly due to the production of particulate phosphorus (PP) through various mechanisms.
