title: Effects of Phosphate in Medium on Protein Secretion in a Protein-Producing Bacterium, Bacillus brevis 47.
abstract: Bacillus brevis 47 secreted up to 1 mg of protein per ml in a chemically defined medium, depending on phosphate concentration. The composition of exoproteins was altered quantitatively by the concentration of external phosphate. Morphologically, B. brevis 47 showed a distinct three-layered cell wall structure and shed the outer two layers during growth.
