Research progress on ethanol production by brown seaweed

As the third-generation bioethanol, the biofuels from macroalgae biomass fermentation have received the widespread attention of reseachers. There are rich resources of brown seaweeds in China, the favorable conditions of bioconversion of brown algae into ethanol have been possessed. However, in order to realize industrial production, we need to obtain fine strain, which can efficiently ferment brown algae by means of isolation and gene engineering, optimize pretreatment and fermentation conditions. This article focused on research situations of resource profile, the raw material pretreatments, microorganisms fermenting different components of algae into ethanol, it also proposed the current problems and prospects for kelp biomass into ethanol by microbial fermentation.
