Leather industry discharges enormous amount of chrome containing leather solid wasted which creates a major disposal problem. Tanned leather solid waste is a complex of hard-to-degrade proteins and chromium. The biotechnological sector allows us to use the waste materials as bacterial substrate for enzyme production. The present work covers potential application in the potato bio-growth as fertilizer. The hydrolysate results from bacterial conversion of leather components. Bacteria was isolated from the composting of leather and incubated into a minimal media for 120 hours at 35°C. In the optimization process maximum proteinase production was 1.223 U/ml. The results obtained suggested that leather debris containing amino-acids and proteins andcan be applied as organic nitrogen soil input.
