Oleidesulfovibrio alaskensis G20 is a gram-negative, mesophilic, sulfate-reducing bacterium known for its biofilm-forming and bio-corroding characteristics. A total of 173 new gene annotations have been identified, encoding electron transportation proteins, among others. These genes are likely involved in extracellular electron transfer and interspecies interactions, highlighting microbial adaptations for extreme anaerobic environments.
Raya et al. (2026) studied this question.
