Unraveling the functional instability of bacterial consortia in crude oil degradation via integrated co-occurrence networks.

ABSTRACT:

Introduction

Soil ecosystems are threatened by crude oil contamination, requiring effective microbial remediation. However, our understanding of the key microbial taxa within the community, their interactions impacting crude oil degradation, and the stability of microbial functionality in oil degradation remain limited.

Methods

To better understand these key points, we enriched a crude oil-degrading bacterial consortium generation 1 (G1) from contaminated soil and conducted three successive transfer passages (G2, G3, and G4). Integrated Co-occurrence Networks method was used to analyze microbial species correlation with crude oil components across G1-G4.

Results and discussion

In this study, G1 achieved a total petroleum hydrocarbon (TPH) degradation rate of 32.29% wi
