Abstract: The present disclosure relates to a hydrolysate of a mixture of lignocellulosic biomass and seaweed biomass. By mixing seaweed biomass with lignocellulosic biomass and then preparing a hydrolysate, lignocellulosic biomass-derived acetic acid is consumed together with seaweed biomass-derived mannitol. As a result, high sugar productivity can be maintained while reducing fermentation inhibitors. Because the present disclosure can solve the problem of lignocellulosic biomass of decreased fermentation efficiency due to lignocellulose-derived fermentation inhibitors and the problem of seaweed biomass of very low productivity in spite of long fermentation time, the hydrolysate according to the present disclosure may be used to produce biofuels and biochemicals economically.

Abstract: The present disclosure relates to a method for separating sugars and acids with reduced energy consumption, including a step of diffusively dialyzing a first acid hydrolysate obtained by saccharifying biomass with an acid solution, thereby preparing a second acid hydrolysate wherein the concentration of the acid solution contained in the acid hydrolysate is decreased; and a step of electrolyzing the second acid hydrolysate, thereby separating sugars from the acid solution, which is advantageous in that less energy is consumed, the separated acid solution can be recycled directly without further treatment due to high concentration and loss of sugars can be minimized.

Abstract: The apparatus includes: a pretreatment tank where biomass and a first acid solution are stirred to extract sugar components from the biomass; a hydrolysis tank where water is added to the pretreated mixture transferred from the pretreatment tank such that the concentration of the acid is reduced and the sugar components are hydrolyzed to produce an acid hydrolyzate; a first sugar-acid separation tank where the acid hydrolyzate is separated into a second acid solution and a first hydrolyzate; a second sugar-acid separation tank where the first hydrolyzate is separated into a third acid solution and a second hydrolyzate; a fermentation tank where the second hydrolyzate is fermented to produce bioenergy; and an acid solution concentration tank where a mixture of the second acid solution transferred from the first sugar-acid separation tank and the third acid solution transferred from the second sugar-acid separation tank is concentrated to a higher level for reuse.
