Environmental performance of biological nutrient removal processes from a life cycle perspective

Bioresource Technology, 2013
The goal of the present study is to assess different alternatives for a wastewater treatment plant module with capacity to remove nutrients biologically, taking into account present Argentine regulations for effluent discharge. A computational modeling tool (GPS-X) was employed to simulate the behavior of the different alternatives, and Life Cycle ...

ADP‐ribosylation: An emerging regulator of the epigenome

Molecular Oncology, EarlyView.
ADP‐ribosylation has emerged as a dynamic epigenetic signaling mechanism that modifies histones and chromatin‐associated proteins. Through coordinated PARylation and MARylation, it integrates with other histone modifications to regulate chromatin structure, transcription factor activity, and gene expression, influencing genome function and disease ...

Comparative Evaluation of Anode Materials for Electrochemical Treatment of Anaerobic Digestate: Ammonia, Phosphorus, COD and Turbidity Removal

Energies
This study assessed the performance of five anode materials (Fe, stainless steel (SS), Al, Zn, and Ti/RuO2–IrO2) in terms of the removal of ammonia, phosphorus, and turbidity from anaerobic digestate using a single-cell hybrid electrocoagulation (EC ...

Kinetic start-up performance of two large treatment plants for nutrient removal

Water Science and Technology, 2001
In 1987 an action plan was passed in the Danish Parliament demanding a considerable reduction of the discharge of nutrients to the aquatic environment in Denmark. Consequently, the two largest wastewater treatment plants in the Copenhagen area had to be upgraded to include nutrient removal.

Bridging the gap: a genetically validated avian chorioallantoic membrane platform for investigation of spontaneous circulating tumor cells

Molecular Oncology, EarlyView.
We established the avian chorioallantoic membrane (CAM) assay as a scalable in vivo model for studying circulating tumor cells (CTCs). Human gastrointestinal tumors spontaneously released genetically validated CTCs that were detected across multiple platforms, demonstrating that the CAM model provides an accessible tool for investigating early cancer ...

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Start-up of a nutrient removal system using Scenedesmus vacuolatus and Chlorella vulgaris biofilms

Bioresources and Bioprocessing, 2019
Microalgal biofilm-based technologies are of strong interest due to their high biomass concentrations and ability to remove nutrients from wastewater, utilize CO2 and produce secondary valuable products. This study investigated the biomass production and
