ABSTRACT
The present study attempts to investigate the microbial communities and their potential to oxidize ammonia and sulfur at different sites of Arctic Fjord by targeted metagenomics. The high throughput sequencing revealed archaeal Thaumarchaeota (79.3%), Crenarchaeota (10.9%), Euryarchaeota (5.4%), and Woesearchaeota (2.9%) across different depths. In contrast, the bacterial communities depict predominance of Proteobacteria (52.6%), which comprises of dominant genera viz. Sulfurovum (11.2%) and Sulfurimonas (6.3%). Characterizing the metabolic potential of microbial communities with prime focus on the ammonia and sulfur cycling revealed the presence of amoABC and narGHYZ/ nxrAB genes encoding key enzymes. The ammonia cycling coupled with an augmentation of members of Nitrosopumilus belonging to the phylum Thaumarcheaota suggests the vital role of archaeal communities. Similarly, the persistence of chemolithoautotrophic members of Sulfurovum and Sulfurimonas along with the anaerobic genera Desulfocapsa and Desulfobulbus harboring SOX (sulfur-oxidation) system indicates the modulatory role of bacterial communities in sulfur cycling.
