Proteomics Faecalicatena sp. DSM22707, Glucose vs Sulfoquinovose

Sulfoquinovose (SQ) is a major organosulfonate in nature, and thus plays an important role in the biogeochemical sulfur and carbon cycles. We identified a bacterial anaerobic consortium, enriched from lake Konstanz, which degraded SQ to isethionate as intermediate and further into acetate and sulfide. By a metagenomic analysis we identified Faecalicatena sp. DSM22707 as major SQ-degrader in the consortium. Strain DSM22707 degraded SQ in pure culture into isethionate and small amounts of sulfolactate.
