We have developed several key technologies for biorefinery of brawn macroalgae with marine microbial resources. Anaerobic digestion has been widely used to treat organic matters including marine macroalgae to recover methane as a biofuel. However, high ash content in marine algae inhibits the digestion, resulting in a decrease in productivity of methane. We discovered that the marine sediments were an excellent marine microbial source for halophilic methane fermentation. The acclimated marine sediments could be applied to the continuous culture for biogas production from non-diluted raw brawn algae with the continuous stirred tank reactor, in which stable biogas production was achieved under saline conditions.
