Abstract
Some strains of Rhizobium japonicum can use hydrogen as an energy source for growth under microaerophilic conditions. Mutant strains have been selected that use hydrogen in the presence of high partial pressures of oxygen. The mutants contain more hydrogenase than the parent strain, both as free-living cells and as bacteroids in nitrogen-fixing soybean root nodules.
摘要
有些根瘤菌（Rhizobium japonicum）菌株可以在微需氧条件下利用氢气作为生长的能源。已经选择了一些突变株，它们可以在高氧分压存在的情况下利用氢气。与亲株相比，突变株在固氮大豆根瘤中的自由生活细胞和类菌体中含有更多的氢化酶。
