| Outline of Final Research Achievements |
An aerobic and heterotrophic bacterium Sphingobium japonicum UT26 shows oligotrophic growth phenotype, i.e., growth on minimal salt medium without the supply of any carbon source accompanying with the CO2-fixation, by the over expression of the adhX gene. Protein product of adhX showed alcohol dehydrogenase activity, and its activity had equilateral correlation with the oligotrophic phenotype. Furthermore, it was strongly suggested that the adhX-dependent oligotrophic phenotype is one of the bacterial fundamental mechanisms for adaptation to oligotrophic conditions.
