Removal of Ibuprofen in Water by Bioaugmentation with CSW11 Isolated from Sewage Sludge-Assessment of Biodegradation Pathway Based on Metabolite Formation and Genomic Analysis.

Ibuprofen (IBP) is one of the most consumed drugs in the world. It is only partially removed in wastewater treatment plants (WWTPs), being present in effluent wastewater and sewage sludge, causing the widespread introduction of IBP as an emergent xenobiotic in different environmental compartments. This study describes the use of CSW11, recently described as an IBP degrader, through bioaugmentation processes for the removal of IBP from water under different conditions (additional carbon sources, various concentrations of glucose and IBP).

Bacterial bioaugmentation for paracetamol removal from water and sewage sludge. Genomic approaches to elucidate biodegradation pathway.

Wastewater treatment plants (WWTPs) are recognized as significant contributors of paracetamol (APAP) into the environment due to their limited ability to degrade it. This study used a bioaugmentation strategy with Pseudomonas extremaustralis CSW01 and Stutzerimonas stutzeri CSW02 to achieve APAP biodegradation in solution in wide ranges of temperature (10-40 °C) and pH (5-9), reaching DT values < 1.5 h to degrade 500 mg L APAP.

An undergraduate service-learning project to teach immunology concepts while increasing healthcare equity by enhancing access to stem cell donors among underrepresented populations.

Active learning has been shown to increase STEM student engagement and decrease the achievement gap among underrepresented students. As a parallel to the lack of equity in STEM education, BIPOC patients who require a life-saving hematopoietic cell transplantation (HCT) are much less likely-sometimes less than half as likely-than individuals of White-European descent to find a suitable donor when using the National Marrow Donation Program (NMDP). The Be the Match (BtM) Registry has made significant improvements in the likelihood of matching underrepresented patients, but the disparity persists.

An In Situ Evaluation of Different CAM Plants as Plant Microbial Fuel Cells for Energy Recovery in the Atacama Desert.

Excess energy derived from photosynthesis can be used in plant microbial fuel cell (PMFC) systems as a sustainable alternative for the generation of electricity. In this study, the in situ performance of CAM (Crassulacean acid metabolism) plants in Calama, in the Atacama Desert, was evaluated for energy recovery using PMFCs with stainless steel AISI 316L and Cu as electrodes. The plant species evaluated included , , , , , and .

Ibuprofen-enhanced biodegradation in solution and sewage sludge by a mineralizing microbial consortium. Shift in associated bacterial communities.

Ibuprofen (IBP) is a widely used drug of environmental concern as emerging contaminant due to its low elimination rates by wastewater treatment plants (WWTPs), leading to the contamination of the environment, where IBP is introduced mainly from wastewater discharge and sewage sludge used as fertilizer. This study describes the application of a consortium from sewage sludge and acclimated with ibuprofen (consortium C7) to accelerate its biodegradation both in solution and sewage sludge. 500 mg L IBP was degraded in solution in 28 h, and 66% mineralized in 3 days.
