Methods of hydrogen production by Thermococcus Onnurineus and Recirculation Culture Medium

摘要

The present invention relates to a method for producing biohydrogen using a Thermococcus onnurinus strain and a recycling medium, and more specifically, culturing the Thermococcus onnurinus NA1 strain in a culture medium, and the Thermococcus in the culture medium produced in the culture. It relates to a method for producing biohydrogen comprising the step of recirculating by administering a recycle liquid from which the Onnurinus NA1 strain has been removed to the culture medium. The biohydrogen production method of the present invention has the advantage of being able to efficiently and economically produce hydrogen gas by increasing the cell viability of the strains of the genus Thermococcus by recycling the culture filtrate from which the strains of genus Thermococcus present in the waste fluid are removed, and increasing the productivity of hydrogen. .
