Exploring the influence of deposit mineral composition on biofilm communities in oil and gas systems.

ABSTRACT:

Introduction

Inside oil and gas pipelines, native microbial communities and different solid compounds typically coexist and form mixed deposits. However, interactions between these deposits (primarily consisting of mineral phases) and microorganisms in oil and gas systems remain poorly understood. Here, we investigated the influence of magnetite (Fe₃O₄), troilite (FeS), and silica (SiO₂) on the microbial diversity, cell viability, biofilm formation, and EPS composition of an oil-recovered multispecies consortium.

Methods

An oilfield-recovered microbial consortium was grown for 2 weeks in separate bioreactors, each containing 10 g of commercially available magnetite (Fe₃O₄), troilite (FeS), or silica (SiO₂) at
