 Rosobacter bacteria are key players in marine biofilms, where they play a crucial role in thiosulfate oxidation. These bacteria have evolved specialized mechanisms to oxidize thiosulfate under both aerobic and anaerobic conditions, which allows them to survive in these environments. Additionally, their ability to form biofilms and promote anaerobic respiration further enhances their importance in the marine environment.
