In this study, novel strains showing better protein degradation activity were isolated for the production of effective compost from garbages. Well growing bacteria with clear zone on the skim milk agar media were isolated . The strain was identified as Bacillus subtilis PNV-1 through various biochemical tests, Bergy's manual of determinative bacteriology and 165 rDNA partial sequence. The extracellular protease of the strain PNV-1 has its activity at broad pH and the optimal temperature was $50^{\circ}C$. Also, the strain PNV-1 was highly tolerant to high concentration of salt, red/black pepper and mustard.
