| Outline of Final Research Achievements |
The intimate relationship between methane-oxidizing bacteria (methanotrophs) and methanol-oxidizing bacteria (methylotrophs) has been known for a long time. The co-existence with methylotrophs has been always explained in terms of cross-feeding. However, the real nature of the relationship remains unknown. In this study, we have isolated novel marine mwethanotroph, Methylocaldum marinum S8, and novel methylotroph, Methyloceanibacter caenitepidi Gela4, that syntrophically grow with M. marinum S8. We also determined complete genomes of the two strains in order to infer their interrelationship.
