title: Comparative growth analysis of the facultative anaerobes Bacillus subtilis, Bacillus licheniformis, and Escherichia coli.
abstract: Bacillus subtilis anaerobic respiration and fermentative growth capabilities were compared to two other facultative anaerobes, Bacillus licheniformis and Escherichia coli. In glycerol defined medium, B. subtilis grew with nitrate, but not nitrite or fumarate, while B. licheniformis grew with nitrate or fumarate, but not nitrite. Growth of E. coli occurred in glycerol defined medium with either nitrate, nitrite, or fumarate. In order to grow by fermentation, B. subtilis required both glucose and pyruvate, while B. licheniformis and E. coli were capable of using either glucose or pyruvate.
