The objective of this study was to demonstrate that industrial wastewater sludge, class II, originary of alimenticeous industry, could be used as a sole raw material to sustain growth of Bacillus subtilis. The growth of one strain of Bacillus subtilis (AP-3), antagonist of phytopathogens, was evaluated in culture media based in diluitions with differents concentrations of sludge obtained in biologicals treatments of wastewater. The sludge showed concentration of organic components in 76,5% that contributed for growth and survival of B. subtilis. The dose of sludge (20% p/v) evaluated was satisfactory para growth of bacteria. Nutrient enrichement did not increased growth of B. subtilis in media with sludge. Culture media based in industrial sludge evaluated would be indicated with of big potential for use large scale
