Macroalgae bioethanol production has been carried out using marine biomass such as sea tangle (Laminaria japonica), sea mustard (Undaria pinnatifida) etc. Seaweeds, macroalgae grow faster than land plant and contain large amount of carbohydrate [1]. Macroalgae can be classified to red, brown and green algaes and contains 53~70%, 30~67% [2] and 48~55% of carbohydrate, respectively. However, the carbohydrate compositions of macroalgae are too complex and variable to degrade to reducing sugar. Therefore, proper saccharification process is required for the ethanol production. Physical, chemical and biological pretreatment and saccharification processes should be developed. Also, the ethanol fermentation process should be developed using proper yeasts. After the evaluation of saccharification and ethanol production processes, simultaneous saccharification and fermentation (SSF) process will be developed for the reduction of processes for cost reduction. The general evaluation on this area for marine bioethanol production and R&D status will be discussed in this topic.
