Figure 3. Taxonomic distribution of prokaryotic 16S rRNA gene reads obtained from metagenomic data sets from two bulk sediment samples at the water-sediment interface (BS; 0-m soil samples 1a-c and 2a and b), two surrounding sediment samples (AS; 3-m soil samples 1a, 1b/1c, 2a, and 2b/2c) and two deposit layer samples (DL; samples 1a-c and 2a and b). All taxonomic groups have a relative abundance of ≥1%. “Other” includes all taxonomic groups with a relative abundance of <1%. Taxonomic identification is given up to order level.
Bacillus spp. are often abundant in soils amended with long-chain alkanes, polysaccharides and polycyclic aromatic hydrocarbons, indicating their potential role in organic matter degradation (Cerniglia 1993; Samanta, Singh and Jain 2002; Ghazali et al. 2004; Kim et al. 2009). Their high relative abundance observed in our study might be explained by their ability to form spores and the production of antimicrobial compounds and antifungal volatiles (Siala, Hill and Gray 1974; Yilmaz, Soran and Beyatli 2006; Zou et al. 2007).
