Development of an oxygen resistant hydrogen bacterium during plate cultivation under high oxygen tension

, : Development of an oxygen resistant hydrogen bacterium during plate cultivation under high oxygen tension. Agricultural & Biological Chemistry 48(1): 165-170

An O2-resistant hydrogen bacterium developed during an autotrophic plate culture under 40% O2. When O2 sensitive strain N34 was incubated under an atmosphere of 50% H2 + 40% O2 + 10% CO2, small white colonies (SW) first formed, and then, large yellow colonies (LY) developed from some of the SW. The LY counts increased gradually. The hydrogenase activity of SW was 1/5 that of LY. The growth lag period of a liquid culture under 40% O2 inoculated with SW was more than 100 h, while it was almost 0 with LY, indicating that SW were O2-sensitive and LY O2-resistant. When a single SW was transferred to a fresh plate culture under 40% O2 at first SW and then LY were formed again. LY were always formed under 40% O2 when a single LY was transferred. SW were apparently formed from O2-sensitive strain N34 whose growth was inhibited under 40% O2 and O2-resistant LY were formed as a result of adaptation of SW to high O2 tension.
