<unk> obacilli are homofermentative, i.e. hexoses are metabolised by glycolysis to<unk> ate as major end product, or heterofermentative, i.e. hexoses are metabolised by the Phosphoketolase pathway to<unk> ate, CO2 and acetate or ethanol as major end products. Most<unk> obacilli are aerotolerant and some species respire if heme and menaquinone are present in the growth medium. Aerotolerance of<unk> obacilli is manganese-dependent and has been explored (and explained) in<unk> iplantibacillus plantarum (previously<unk>  plantarum).<unk> obacilli generally do not require iron for growth. The<unk> obacillaceae are the only family of the<unk> ic acid bacteria (LAB) that includes homofermentative and heterofermentative organisms; in the<unk> obacillaceae, homofermentative or heterofermentative metabolism is shared by all strains of a genus.<unk>  species are all homofermentative, do not express pyruvate formate lyase, and most species do not ferment pentoses. In L. crispatus, pentose metabolism is strain specific and acquired by lateral gene transfer.
