Abstract
Today, studying the diversity of microbial communities associated with samples of highly mineralized oil industry waters is expanding our knowledge of the ecology of polyextremophilic microorganisms. During this work, samples of produced water and wastewater from the oil industry were thoroughly analyzed. The analyzed waters were characterized by very high concentrations of Na+, Ca2+, Mg2+, and Cl– ions. Furthermore, enriched and pure bacterial cultures from oilfield waters were obtained. Additionally, enriched cultures were analyzed using high-throughput sequencing of the bacterial 16S rRNA gene on the Illumina platform. Among the representatives of the studied bacterial communities, members of the genera Halomonas, Marinobacter, Modicisalibacter, Bacillus, Clostridium, Prauserella, and Rubrobacter were identified. They can be considered for various biotechnological applications.
