Total amount of fishery output of Korea is approximately 3 million tons per year. Of the output, the production of fishes and seaweeds account for 75%. Every year, 28 percents (0.7 million tons) of wastes occur during the fishery process. Due to London convection, ocean disposal of fishery wastes has been strictly prohibited since 2012, treatment, which issues the recycle of fishery wastes. Fish waste contains proteins and lipids, and green seaweed is abundant in carbohydrates such as cellulose, pectin etc. To degrade these polymers simultaneously, 12 potential microorganisms were developed. By the antagonism test on nutrient broth agar plate, it was found that was no antagonism between them. To characterize the treatment of fishery waste, was operate in a 1L 5-neck flask (with 600ml of working volume) containing the mixed fishery waste of mackerel residues and green seaweed. The amount of inoculums was 12g of mixed microbes and the flask was incubated for 15 days at 40℃ and 100 rpm. With measurements of pH, DO, and ORP, the degradation of fishery waste was analyzed by the changes of concentrations of COD, TN, amino acid, and reducing sugars.
