Distinct denitrification phenotypes in closely related bacteria: clues to understanding variations in nitrite accumulation among Stutzerimonas strains

Martin Menestreau, Daniel Aleksanteri Milligan, Louise B. Sennett, Linda Liberg Bergaust, Lars Reier Bakken, Gary Rowley, Morten Kjos, James P. Shapleigh, Åsa Frostegård

The paper identifies three nitrite accumulation phenotypes in Stutzerimonas strains and links them to differences in nitrate reduction and nitrite reductase genes.

Two Small Proteins Enable N2O Reduction in Acidic Environments

Xinhui Wang, Leying Meng, Hu Li, Yu Zhang, Minghou Li, Baoyu Xiang, Jing Zhu, Chen Li, Yang Chen, Siyu Yu, Xiaoyan Pang, Jianwen Wei, Menghui H. Zhang, Lars Reier Bakken, Åsa Frostegård, , Xiaojun Zhang

The paper identifies two proteins, NosP and NosQ, that enable N2O reduction in acidic environments by protecting the NosZ enzyme from low pH.

Optimizing Carbon Sources to Promote Soil Denitrifiers: Lessons for Incubations, Enrichments, and Bioaugmentation

Louise B. Sennett, Alicia Caro Pascual, Peter Dörsch, James P. Shapleigh, Åsa Frostegård

The paper evaluates twelve carbon sources to identify those that support denitrification while limiting competition from fermentation and DNRA in soil, finding that clover extract supports denitrification but also promotes competing pathways.
