Abstract
Highly polluted waters profoundly promoted microbial activities and vice versa. Although microbial community structures and bioprocesses in polluted environments have been fully investigated, they are rarely uncovered in abandoned and highly polluted aquatic environment, especially in a seasonally frozen area. East Lake had been polluted by surrounding paper mills and dairy plants from the 1960s to the early 2000s. Under low biodegradability (BOD/COD ratio<0.2) and alkalic (pH > 9) conditions, a unique microbiome was discovered in East lake. Proteobacteria was the largest taxonomic group in the microbial community, covering almost half of the top-100 genera. Among them, seven genera are sulfate-reducing bacteria, including Desulfuromusa, Desulfuromonas, Desulfobulbus, Desulfocapsa, Desulfurivibrio, Desulfatiglans, and Desulfomicrobium. Functional analysis revealed abundant predicted functional genes for the respiration of sulfur compounds and sulfate respiration. Great vertical variations were found to both microbial community structures and predicted functions. This work provides unique evidence for future microbiome studies of nutrient-rich, alkalic, and seasonally frozen water habitats.
