Abstract:
As a marine biomass species to be employed for biorefinery, our group selected kelp due to its large availability in Japan and oceans nearby. For utilization of kelp, hydrothermal pretreatment is effective for releasing organics and inorganics in liquid phase so that microorganism used in the following biochemical conversion can get easier access to its component. The components will be utilized for value-added oil production, methane fermentation, and biochemical metal recovery. However, effect of drying and salt on the behavior of organics and inorganics of the kelp during hydrothermal pretreatment has not been elucidated. Thus, kelp was treated hydrothermally with and without drying treatment and with and without salt. Organic compounds observed included mannitol, formic acid, acetic acid, propionic acid, furfural, and 5-hydroxymethylfurfural. Behavior of inorganic kelp component was also determined. Drying did not affect the behavior of kelp. Effect of salt was negligible for organic compounds, but inorganic component was affected by salt addition.
