Abstract
Under laboratory conditions it has been found that most strains of Aerobacillus polymyxa split off variants that differ substantially in: colony formation; appearance of wheat mashes after fermentation; filterability of these mashes; and their ability to produce 2,3-butanediol and ethanol. It has been impossible to demonstrate a close correlation between particular colony types and their usefulness for commercial 2,3-butanediol production. By selection it has been possible to obtain strains that are excellent both from the standpoint of mash filterability and product yield. Preservation of cultures in lyophile tubes prevents further variation during storage.Keywords
