Abstract: An aerobic mesophilic Gram-negative rod-shaped bacterium isolated from fermenting bean processing effluent (BPE) and identified as Stenotrophomonas acidaminiphila strain BPE4, produced an extracellular protease on skimmed-milk minimal medium. Time-course of enzyme production revealed peak productivity at 12 h but enzyme concentration gradually increased till 36 h beyond which both concentration and productivity gradually decreased. Evaluation of the influences of major nutritional sources on enzyme concentration revealed significant (P
