Microbial Diversity of Hydrocarbon-Contaminated Soils of the Franz Josef Land Archipelago

We conducted an experiment to investigate the effects of 232Th on soil enzymes and microbial diversity in soils. Under each treatment, elevated 232Th obviously inhibited the activity of soil enzymes such as urease (UR), dehydrogenase (DH), catalase (CAT), phosphatase (PHO) and aryl sulfatase (AS). In each treatment, Proteobacteria was the most dominant flora followed by Actinobacteria and Acidobacteria. Pseudomonas sp. was the dominant strain. This study might provide the preliminary analysis of soil enzymes and microbial diversity in Th contaminated soils.

Operational Taxonomic Units

Sediment microbial fuel cells (SMFCs) are attractive devices to in situ power environmental monitoring sensors and bioremediate contaminated soils/sediments. Burial depth of the anode was verified to affect the performance of SMFCs. The present research evaluated the differences in microbial community structure of anodic biofilms located at different depth. It was demonstrated that both microbial diversity and community structure of anodic biofilms were influenced by the depth of anode location. Microbial diversity decreased with increased anodic depth. The number of the operational taxonomic units (OTUs) was determined as 1438 at the anode depth of 5 cm, which reduced to 1275 and 1005 at 10 cm and 15 cm, respectively. Cluster analysis revealed that microbial communities of 5 cm and 10 cm were clustered together, separated from the original sediment and 15 cm. Proteobacteria was the predominant phylum in all samples, followed by Bacteroidetes and Firmicutes. Beta-and Gamma-proteobacteria were the most abundant classes. A total of 23 OTUs showed high identity to 16S rRNA gene of exoelectrogens such as Geobacter and Pseudomonas. The present results provided insights into the effects of anode depth on the performance of SMFC from the perspectives of microbial community structure.
