Title:
HIGH CONCENTRATION THERMOCOCCUS ONNURINEUS 480T STRAIN, AND HYDROGEN PRODUCING METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/008786
Kind Code:
A1
Abstract:
The present invention relates to a Thermococcus onnurineus 480T (deposit number: KCTC13046BP) strain, and a hydrogen producing method comprising: a step (a) of supplying carbon monoxide to the strain in claim 1 and culturing the same; and (b) obtaining a high concentration of the cells from the culture thereof. According to the present invention, the strain adapted to 100% carbon monoxide, and compared to those of a conventional 156T, the growth rate increased by 5.5% and the biomass increased by approximately 55%, and thus the hydrogen production capacity increased by approximately 30%, and the rate of conversion of carbon monoxide to hydrogen increased by 54%. Therefore, the strain has significantly superior properties compared to those of a conventional strain.
