Demonstration of an Integrated Process for Manure-Based Nitrogen Recovery Using the Biopolymer Cyanophycin

This paper demonstrates a process for recovering nitrogen from manure using cyanophycin produced by genetically modified E. coli, showing the potential for sustainable nitrogen recovery from agricultural waste.

Nitrous oxide production, mechanisms, and modeling from a denitrifying phosphorus removal bioreactor

This study investigates N2O production in a wastewater treatment reactor, identifies key microbial pathways, and models N2O generation using metagenomic data.

Biomass segregation between biofilm and flocs improves the control of nitrite-oxidizing bacteria in mainstream partial nitritation and anammox processes

The paper investigates how biomass segregation between biofilm and flocs affects nitrite-oxidizing bacteria control in hybrid PN/A systems, showing that low DO promotes NOB washout from flocs.
