Comments p.2 left column 2nd paragraph:"An important class of industrial production hosts are the gram-positive bacilli as efficient secretors of enzymes and producers of antibiotics, purine nucleotides or vitamins. The industrially and scientifically most relevant representative of this group is B. subtilis, which is used extensively for enzyme and biochemicals production [ref 5], in particular for the large-scale production of vitamin B2, riboflavin [refs 6-8]. While B. subtilis fulfills most of the industrially desirable host criteria, it does not have a particularly low maintenance energy coefficient (0.44 mmol g^-1 h^-1 [primary source 9]) when compared to, for example, B. licheniformis (0.24 mmol g^-1 h^-1 [primary source 10]) or Klebsiella aerogenes (0.3 mmol g^-1 h^-1 [primary source 11]).
