• The growth characteristics of the oxygen-resistant strain of hydrogen bacterium N34 in a 40% O2-culture were compared with those in a 4% O2-culture in order to clarify the mechanism of oxygen-resistance. Growth inhibition was observed with decreased CO2 tension indicating the inhibition of CO2-fixation. Cell growth in 40% O2-culture was associated with stimulated oxyhydrogen reaction. There was no significant difference in cell composition. Each of the efficiency of energy conversion and the yield coefficients, YH2 and YO2, in the 40% O2-culture was about half of that in the 4% O2-culture. The yield coefficient, YCO2, or the carbon recovery, however, was almost equal between the two kinds of cultures. The mechanism of oxygen-resistance was discussed.
