We present the genome sequence of Desulfovibrio africanus strain PCS, an anaerobic sulfate-reducing bacterium. This bacterium can reduce metals and is predicted to produce methylmercury.
Area of Science:
- Microbiology
- Genomics
- Environmental Science
Background:
- Desulfovibrio africanus strain PCS is an anaerobic sulfate-reducing bacterium (SRB).
- SRBs play crucial roles in biogeochemical cycles.
- This strain was isolated from Paleta Creek sediment, San Diego, CA.
Purpose of the Study:
- To present the complete genome sequence of Desulfovibrio africanus strain PCS.
- To provide genomic insights into the metabolic capabilities of this SRB.
- To facilitate further research on its environmental significance.
Main Methods:
- Isolation and cultivation of Desulfovibrio africanus strain PCS.
- Whole-genome sequencing and assembly.
- Bioinformatic analysis of the genome sequence.
Main Results:
- The genome sequence of Desulfovibrio africanus strain PCS is now available.
- The genome reveals the bacterium's capacity for metal reduction (Fe(III) and Cr(VI)).
- Genomic analysis predicts the production of methylmercury by strain PCS.
Conclusions:
- The genome sequence provides a valuable resource for studying Desulfovibrio africanus PCS.
- Understanding its metabolic pathways can inform bioremediation strategies.
- Further research is warranted to confirm methylmercury production and its ecological impact.
