Assessment of the Microbial Communities in Soil Contaminated with Petroleum Using Next-Generation Sequencing Tools

Microbial communities are known to play a principal role in petroleum degradation. This study tries determine the composition of bacteria selected crude oil-contaminated soil from Tabasco and Tamaulipas states, Mexico. We determined microbial populations living under these conditions. evaluated structure diversity bacterial contaminated samples. The most abundant phylum is proteobacteria. Next Generation Sequencing (NGS) analysis sampled soils both states revealed that this has relative abundance among identified phyla. heatmap represented percentage each genus within sample clustered four samples into two groups. Moreover, allowed us identify many genera alkaline Tamaulipas, such as Skermanella sp., Azospirillum sp. Unclassified species Rhodospirillaceae family higher abundance. Meanwhile, acidic Tabasco, we Thalassospira, members Sphingomonadaceae Alphaproteobacteria class with Alpha showed low (Shannon Simpson index); Chao observed Regions. These results suggest may possess ability degrade petroleum, further studies future should elucidate their
