This book examines how soybean curd residue is an efficient nutrient for higher production of a lipopeptide antibiotic, iturin A in solid-state fermentation (SSF) of Bacillus subtilis. This cultured solid can also be applied to soil to control plant diseases. The high production of iturin A in SSF may be due to biofilm formation of B. subtilis on the surface of the soybean curd residue. In order to prove this speculation, B. subtilis was grown both in an artificial air membrane surface (AMS) reactor where a biofilm was formed on the membrane and by liquid submerged cultivation (SmF) in suspended culture by using the same nutrients.
