The biological sink of atmospheric H2 is more sensitive to spatial variation of microbial diversity than N2O and CO2 emissions in an agroecosystem

X. Baril, A.-A. Durand, N. Srei, S. Lamothe, C. Provost, C. Martineau, C. Guertin, K. E. Dunfield, P. Constant

The study examines how microbial diversity affects H2, N2O, and CO2 fluxes in agroecosystems, finding H2 flux is most sensitive to spatial microbial diversity variation.

Denitrifying metabolism of the methylotrophic marine bacterium Methylophaga nitratireducenticrescens strain JAM1

F. Mauffrey, A. Cucaita, P. Constant, R. Villemur

This study shows Methylophaga nitratireducenticrescens JAM1 can reduce nitrate to nitrite, nitric oxide to nitrous oxide, and nitrous oxide to nitrogen gas under anoxic conditions, using these compounds as sole electron acceptors for growth.
