| Research Abstract |
Methanol-utilizing bacteria, methylotroph, are distributed widely into environment, however the source of methanol in environment have been unclear for a long time. It was recently reported that the plants released a large amounts of methanol into the environment by hydrolyzing pectin methyl ester in around cell wall with growing. And that is utilized by methylotrophic bacteria for carbon or energy source. Furthermore, that is utilized as a mediator for symbiosis between plants and methylotroph.
In this study, we tried to understand the symbiotic relationship between plants and methylotrophic bacteria. We studied some substances as symbiotic materials such as pyrroloquinoline quinone (PQQ), CO2 and metal ions (especially calcium and rare earth elements) for exchange between plants and methylotrophic bacteria.
