These substrates are sources of carbon and nitrogen that are essential components to culture media composition. Since 1970 our research group are studying both the submerged (1) and semisolid fermentations (2) and two patents (3,4) from the processes were developed. Corn steep liquor and sugar cane molasses were determined as the principal components of the culture media. This paper deals with the process, advantages and problems and the use of low cost raw material available in Brazil. The group intends to develop local technology to produce Bacillus thuringiensis, just to useagainst agricultural pests that are responsible to 40% of losses in field, harvested and stored products. These losses cause price increments in the final product and contribute to maximize hungry and poverty problems, in Brazil.  abiological control  aculture media  atoxicity  awastewater  aBacillus Thuringiensis  aAnticarsia gemmatallis  aBioinsecticide  aCrop protection  aEntomopathogenic bacterium  aFermentation process  aRaw material  aResidues  aSugar cane molasses1 aCAPALBO, D.
