Essential role of flavohemoglobin in long-term anaerobic survival of Bacillus subtilis.
A Bacillus subtilis culture incubated anaerobically in nitrate-containing medium lost viability during the first 3 days but recovered thereafter. A flavohemoglobin mutant showed very poor survival under these conditions unless the cells were prevented from carrying out nitrate respiration.
