Abstract: An attempt has been made to utilize the silkworm pupal waste for mass cultivation of biopesticide bacterium, Bacillus thuringiensis. The mass production potential was tested in a semi solid state fermentation set-up and the dry pupal waste powder was analyzed for carbon, lipid, protein and pH before and after solid state fermentation, where viable spore count (VSC) was taken as a criteria for evaluating the efficiency of pupal waste medium. A very high VSC of 369x10⁹ was obtained in the present investigation.
