Abstract
- An anaerobic, mesophilic, chemolithoautotrophic, and acetogenic bacterial strains ES2 and ES3 were isolated from sediment of Eulsukdo, a delta island in South Korea. The 16S rRNA gene sequence analysis revealed that strains ES2 and ES3 were most closely related to Acetobacterium fimetarium (96.8% and 97.0%, respectively) and each other showed 97.9% similarity. Both strains clustered in coherent branch and were phylogenetically located between the genera Acetobacterium and Eubacterium. Physiologically the two strains were mesophilic but showed difference in optimum pH and salinity for growth; those of ES2 were pH 7.8 and 0.5% NaCl and ES3 were pH 6.8 and 2.5% NaCl. The DNA G+C content of the strains ES2 and ES3 was 39.6-40.7 mol%. The genome size of the strains ES2 and ES3 was 3.76 Mbp and 3.39 Mbp, respectively. Both the strains ES2 and ES3 could grow with CO2/H2, CO, and formate as the sole sources of carbon and energy. Genomic evidence for the Wood-Ljungdahl pathway in both the strains reflects chemolithoautotrophic growth. Synteny analysis revealed that genome arrangement of two novel strains were close to Acetobacterium woodii than Eubacterium limosum.
