| Research Abstract |
While methane production was not observed in the control Wakasa bay sediment (Japan) without substrate addition, methane production was drastically enhanced by adding trimethylamine (TMA), significantly increased by adding dimethyl sulfide (DMS) and slightly increased by acetate. After incubation with TMA, relative abundance of Methanococcoides-affiliated clones was drastically increased. Methylotrophic methanogens might have an important role for methane production cycle in coastal marine sediments. Following the addition of 11 different types of microalgal cells to coastal marine Maizuru Bay sediment, the highest methane production was recognized from sediment containing the dinoflagellate Heterocapsa circularisquama. These results indicate that the Maizuru Bay coastal marine sediment has potential for methanogenic activity and that microalgal cell addition to coastal sediments leads to methane fermentation.
