Abstract
The composition and application of a single, chemically defined medium or growth and sporulation of Bacillus subtilis is described. At 37 degrees C cells grew with a doubling time of about 40 min; cultures attained near-maximal spore formation (70 to 80% by 12 h after the end of exponential growth and produced 1 X 10(9) to 2 X 10(9) heat-resistant free spores at 24 h. Dipicolinic acid production was completed between 7 and 11 h. Cells grown in the single, chemically defined medium excreted levels of serine and neutral proteases comparable to those excreted in nutrient broth medium.Entities:
