Comparative study of <i>nosZ</i>I and <i>nosZ</i>II clade isolates: insights into their responses to environmental variables and soil fertilization types.

ABSTRACT:

Introduction

Soil nitrous oxide (N₂O) emissions are a major contributor to global warming and climate change. Microbial N₂O reduction via the nosZ gene-classified into clade I and clade II-is the only known biological sink for N₂O.

Methods

In this study, we isolated two N₂O-reducing bacterial strains: an Enterobacter sp. harboring nosZ clade I (nosZI) and a Pseudomonas sp. harboring nosZ clade II (nosZII). We evaluated their performance under different environmental conditions and their effects on N₂O emissions from agricultural soils subjected to varying fertilization strategies.

Results

Pure culture experiments revealed that growth and N₂O-reducing acti
