In this study, we use seaweed industrial wastes as raw materials, research the comprehensive utilization of wastes for the purpose of solving environment pollution, explore the way of seaweed industrial wastes efficiently transforming into fuel ethanol to increase economic benefit. The raw material was handled by the simple crushing processing, using the cellobiose mixed with cellulose enzyme as the hydrolysis enzyme, to research each index of fermentation zymolysing in this study. Compare the Simultaneous Saccharificafion and Fermentation with the Separate Hydrolysateand Fermentation to decide the optimal fermentation seaweed processing waste method.While marine-derived resource, Laminaria japonica is a type of brown algae which could be used for the production of iodine, mannitol, and alginate. The utilization of seaweeds which could be looked as an energy resource to produce biogas has been studied. Floating residue (FR), the surplusage which is massively produced in the alginate extracting process, has large amounts of cellulosic materials. The technical feasibility of FR utilization as a resource of renewable energy was investigated in this paper.There is a little research about comprehensive utilization of seaweed industrial into fuel ethanol. The current bioethanol transformations are mainly using terrestrial plants as raw materials, the use of marine biology as raw materials are not the focus point. Compared the traditional terrestrial plants with Marine biological, no matter in raw material supply point, or in value point, marine biological have incomparable advantage. In addition, if that the seaweed industrial wastes transforming into fuel ethanol can become ture, it will help to solve global energy problem and increase the seaweed industry economic value, and reduce environmental pollution and other related problems.In this experiment, firstly the yeast was researched by the fermentation during the yeast's screening. Because of the different yeast fermentation temperature and different ability to ferment, the best yeast needs to be selected. In the same fermentation conditions the best temperature of each yeast's fermentation was got through the ethanol's output in using glucose, and then The condition of each yeast using the simple sugars in their optimal temperature was studied, I found that S. cerevisiae H-2 yeast's optimal fermentation temperature is fourty, S. cerevisiae H-3 yeast's optimal fermentation temperature is fourty-two, S. cerevisiae B-1 yeast's optimal fermentation temperature is thirty-six, S. cerevisiae H-1 yeast's optimal fermentation temperature is twenty-eight, S. cerevisiae B-3 yeast's optimal fermentation temperature is thirty-six.In the exploration of glycolysis and zymolysing, the zymolysing's temperature was investigated, cellulose enzyme's quantity, quantity of Inoculation amount, nutrients'influence of seaweed industrial wastes'enzyme, cellulose cellobiose composite enzyme's effection to yeast fermentation, and the 50 degree celsius's condition which was determined is cellulose cellobiose composite enzyme optimal enzyme solution temperature, cellulose cellobiose composite enzyme has some efficiency for ethanol's production, but the impact is not a lot, 10% yeast inoculation amount is the optimum inoculation quantity.In the comperation of Simultaneous Saccharificafion and Fermentation with the Separate Hydrolysateand Fermentation, we decide the efficiency of Simultaneous Saccharificafion and Fermentation through the comperation of ethanol's outputs. The results show that: After the synchronous saccharification and fermentation, seaweed industrial wastes could be convertinto ethanol, with thirteen percent of coversion.
