Abstract: The present invention relates to a Thermococcus onnurineus NA1 mutant having an increased ability to produce hydrogen from formate and a method of producing hydrogen the same. The Thermococcus onnurineus NA1 mutant according to the invention has an increased ability to produce hydrogen in a formate-containing medium compared to wild-type Thermococcus onnurineus NA1 and shows an increase in growth rate compared to the wild-type. The use of the mutant strain according to the invention can produce hydrogen with high efficiency from formate.
